Lôn Eifion is the section which runs for 20 km (12 mi) from Caernarfon to Bryncir along most of the former Caernarfon to Afon Wen line. This line was that of

274-534: A navy and some form of coast guard . Coasts, especially those with beaches and warm water, attract tourists often leading to the development of seaside resort communities. In many island nations such as those of the Mediterranean , South Pacific Ocean and Caribbean , tourism is central to the economy . Coasts offer recreational activities such as swimming, fishing, surfing, boating, and sunbathing . Growth management and coastal management can be

411-419: A Labour dominance of Welsh politics that continued into the 21st century. After economic growth in the first two decades of the 20th century, Wales's staple industries endured a prolonged slump from the early 1920s to the late 1930s, leading to widespread unemployment and poverty. For the first time in centuries, the population of Wales went into decline; unemployment reduced only with the production demands of

548-421: A Welsh constituency at Westminster. Yet by 1906, industrial dissension and political militancy had begun to undermine Liberal consensus in the southern coalfields. In 1916, David Lloyd George became the first Welshman to become Prime Minister of Britain. In December 1918, Lloyd George was re-elected as the head of a Conservative-dominated coalition government, and his poor handling of the 1919 coal miners' strike

685-478: A challenge for coastal local authorities who often struggle to provide the infrastructure required by new residents, and poor management practices of construction often leave these communities and infrastructure vulnerable to processes like coastal erosion and sea level rise . In many of these communities, management practices such as beach nourishment or when the coastal infrastructure is no longer financially sustainable, managed retreat to remove communities from

822-732: A feat with neither precedent nor successor." Owain Gwynedd (1100–1170) of the Aberffraw line was the first Welsh ruler to use the title princeps Wallensium (prince of the Welsh), a title of substance given his victory on the Berwyn range , according to Davies. During this time, between 1053 and 1063, Wales lacked any internal strife and was at peace. Within four years of the Battle of Hastings (1066), England had been completely subjugated by

959-689: A legal unit in its own right, although it remains part of the single jurisdiction of England and Wales . The Senedd has the authority to draft and approve laws outside of the UK Parliamentary system to meet the specific needs of Wales. Under powers approved by a referendum held in March 2011, it is empowered to pass primary legislation, at the time referred to as an Act of the National Assembly for Wales but now known as an Act of Senedd Cymru in relation to twenty subjects listed in

1096-655: A much higher capacity for carbon sequestration than many terrestrial ecosystems , and as such can play a critical role in the near-future to help mitigate climate change effects by uptake of atmospheric anthropogenic carbon dioxide . However, the economic importance of coasts makes many of these communities vulnerable to climate change , which causes increases in extreme weather and sea level rise, as well as related issues like coastal erosion , saltwater intrusion , and coastal flooding . Other coastal issues, such as marine pollution , marine debris , coastal development, and marine ecosystem destruction, further complicate

1233-653: A proper name to the coast of the Ligurian Sea , in the form riviera ligure , then shortened to riviera . Historically, the Ligurian Riviera extended from Capo Corvo (Punta Bianca) south of Genoa , north and west into what is now French territory past Monaco and sometimes as far as Marseilles . Today, this coast is divided into the Italian Riviera and the French Riviera , although

1370-435: A provider of sediment for coastlines of tropical islands. Like the ocean which shapes them, coasts are a dynamic environment with constant change. The Earth 's natural processes, particularly sea level rises , waves and various weather phenomena, have resulted in the erosion , accretion and reshaping of coasts as well as flooding and creation of continental shelves and drowned river valleys ( rias ). More and more of

1507-464: A series of castles: Beaumaris , Caernarfon , Harlech and Conwy . His son, the future Edward II , was born at Caernarfon in 1284. He became the first English prince of Wales in 1301, which at the time provided an income from northwest Wales known as the Principality of Wales . After the failed revolt in 1294–1295 of Madog ap Llywelyn – who styled himself Prince of Wales in

1644-456: A shoreline configuration. Swash is the shoreward flow after the break, backwash is the water flow back down the beach. The relative strength of flow in the swash and backwash determines what size grains are deposited or eroded. This is dependent on how the wave breaks and the slope of the shore. Depending on the form of the breaking wave, its energy can carry granular material up the beach and deposit it, or erode it by carrying more material down

1781-425: A slightly different way in discussions of legal and economic boundaries (see territorial waters and international waters ) or when considering the geography of coastal landforms or the ecological systems operating through the continental shelf ( marine coastal ecosystems ). The research on coastal waters often divides into these separate areas too. The dynamic fluid nature of the ocean means that all components of

1918-620: A system of government with a separate executive, the Welsh Government, drawn from and accountable to the legislature, the National Assembly. Following a successful referendum in 2011, the National Assembly was empowered to make laws, known as Acts of the Assembly, on all matters in devolved subject areas, without requiring the UK Parliament's approval of legislative competence. It also gained powers to raise taxes. In May 2020,

2055-533: A varying degree and (since 2011) Welsh is the only official ( de jure ) language in any part of Great Britain. Wales is a country that is part of the sovereign state of the United Kingdom. ISO 3166-2:GB formerly defined Wales as a principality, with England and Scotland defined as countries and Northern Ireland as a province. However, this definition was raised in the Welsh Assembly in 2010 and

2192-589: A victory for the Celtic Britons at Badon Hill against the Saxons, which was attributed to Arthur by Nennius . Having lost much of what is now the West Midlands to Mercia in the 6th and early 7th centuries, a resurgent late-7th-century Powys checked Mercian advances. Æthelbald of Mercia , looking to defend recently acquired lands, had built Wat's Dyke . According to Davies, this had been with

2329-529: A wide range of sessile animals (e.g. mussels , starfish , barnacles ) and various kinds of seaweeds . In physical oceanography , a shore is the wider fringe that is geologically modified by the action of the body of water past and present, while the beach is at the edge of the shore, representing the intertidal zone where there is one. Along tropical coasts with clear, nutrient-poor water, coral reefs can often be found between depths of 1–50 m (3.3–164.0 ft). According to an atlas prepared by

2466-599: Is Cymry , and Cymru is the Welsh name for Wales. These words (both of which are pronounced [ˈkəm.rɨ] ) are descended from the Brythonic word combrogi , meaning "fellow-countrymen", and probably came into use before the 7th century. In literature, they could be spelt Kymry or Cymry , regardless of whether it referred to the people or their homeland. The Latinised forms of these names, Cambrian , Cambric and Cambria , survive as names such as

2603-541: Is a coastline that has experienced a fall in sea level, because of either a global sea-level change, or local uplift. Emergent coastlines are identifiable by the coastal landforms , which are above the high tide mark, such as raised beaches . In contrast, a submergent coastline is one where the sea level has risen, due to a global sea-level change, local subsidence , or isostatic rebound . Submergent coastlines are identifiable by their submerged, or "drowned" landforms, such as rias (drowned valleys) and fjords According to

2740-521: Is a generally mountainous country on the western side of central southern Great Britain. It is about 170 miles (270 km) north to south. The oft-quoted " size of Wales " is about 20,779 km (8,023 sq mi). Wales is bordered by England to the east and by sea in all other directions: the Irish Sea to the north and west, St George's Channel and the Celtic Sea to the southwest and

2877-489: Is coal mining which became the industry synonymous with Wales and its people. Initially, coal seams were exploited to provide energy for local metal industries but, with the opening of canal systems and later the railways, Welsh coal mining saw an explosion in demand. As the South Wales Coalfield was exploited, Cardiff, Swansea, Penarth and Barry grew as world exporters of coal. By its height in 1913, Wales

3014-528: Is connected to marine pollution which can occur from a number of sources: Marine debris (garbage and industrial debris); the transportation of petroleum in tankers , increasing the probability of large oil spills ; small oil spills created by large and small vessels, which flush bilge water into the ocean. Marine pollution occurs when substances used or spread by humans, such as industrial , agricultural and residential waste , particles , noise , excess carbon dioxide or invasive organisms enter

3151-461: Is described as a country rather than a principality.' In the House of Commons – the 650-member lower house of the UK Parliament – there are 32 members of Parliament (MPs) who represent Welsh constituencies . At the 2024 general election , 27 Labour and Labour Co-op MPs were elected, along with 4 Plaid Cymru MPs and 1 Liberal Democrat MP from Wales. The Wales Office is a department of

3288-415: Is extremely important to geologists. These provide vital clues for reconstructing the geography of ancient continents ( paleogeography ). The locations of these beds show the extent of ancient seas at particular points in geological time, and provide clues to the magnitudes of tides in the distant past. Sediments deposited in the shoreface are preserved as lenses of sandstone in which the upper part of

3425-458: Is largely mountainous with its higher peaks in the north and central areas, including Snowdon ( Yr Wyddfa ), its highest summit. The country lies within the north temperate zone and has a changeable, maritime climate . Its capital and largest city is Cardiff . A distinct Welsh culture emerged among the Celtic Britons after the Roman withdrawal from Britain in the 5th century, and Wales

3562-408: Is more important. Macrotidal coasts lack barrier islands and lagoons , and are characterized by funnel-shaped estuaries containing sand ridges aligned with tidal currents. Wave action is much more important for determining bedforms of sediments deposited along mesotidal and microtidal coasts than in macrotidal coasts. Waves erode coastline as they break on shore releasing their energy; the larger

3699-423: Is moved along the coastline by the waves. This forms an abrasion or cliffed coast . Sediment deposited by rivers is the dominant influence on the amount of sediment located in the case of coastlines that have estuaries. Today, riverine deposition at the coast is often blocked by dams and other human regulatory devices, which remove the sediment from the stream by causing it to be deposited inland. Coral reefs are

3836-412: Is the counterintuitive observation that the coastline of a landmass does not have a well-defined length. This results from the fractal curve –like properties of coastlines; i.e., the fact that a coastline typically has a fractal dimension . Although the "paradox of length" was previously noted by Hugo Steinhaus , the first systematic study of this phenomenon was by Lewis Fry Richardson , and it

3973-416: Is the dominant language in parts of the north and west , with a total of 538,300 Welsh speakers across the entire country. Wales has four UNESCO world heritage sites , of which three are in the north. The English words "Wales" and "Welsh" derive from the same Old English root (singular Wealh , plural Wēalas ), a descendant of Proto-Germanic * Walhaz , which was itself derived from

4110-511: The Aberffraw dynasty from Gwynedd and Powys and then codified Welsh law in the 940s. Gruffydd ap Llywelyn was the only ruler to unite all of Wales under his rule, described by one chronicler after his death as king of Wales . In 1055 Gruffydd ap Llywelyn killed his rival Gruffydd ap Rhydderch in battle and recaptured Deheubarth . Originally king of Gwynedd, by 1057 he was ruler of Wales and had annexed parts of England around

4247-462: The Aegean Sea . The following articles describe some coastal landforms: "Coastal waters" (or "coastal seas") is a rather general term used differently in different contexts, ranging geographically from the waters within a few kilometers of the coast, through to the entire continental shelf which may stretch for more than a hundred kilometers from land. Thus the term coastal waters is used in

4384-884: The Bristol Channel to the south. Wales has about 1,680 miles (2,700 km) of coastline (along the mean high water mark), including the mainland, Anglesey , and Holyhead . Over 50 islands lie off the Welsh mainland, the largest being Anglesey, in the north-west. Coastline Coasts are important zones in natural ecosystems , often home to a wide range of biodiversity . On land, they harbor important ecosystems such as freshwater or estuarine wetlands , which are important for bird populations and other terrestrial animals . In wave-protected areas, they harbor salt marshes , mangroves or seagrasses , all of which can provide nursery habitat for fin fish , shellfish , and other aquatic animals . Rocky shores are usually found along exposed coasts and provide habitat for

4521-541: The Cambrian Mountains and the Cambrian geological period. Wales has been inhabited by modern humans for at least 29,000 years. Continuous human habitation dates from the end of the last ice age , between 12,000 and 10,000  years before present (BP) , when Mesolithic hunter-gatherers from Central Europe began to migrate to Great Britain. At that time, sea levels were much lower than today. Wales

4658-616: The Carnarvonshire Railway (later LNWR and London, Midland and Scottish Railway ), and joined with the Cambrian Coast Line at Afon Wen. Running alongside for part of the way is the trackbed of the old Nantlle Tramway , along which horse-drawn trams carried slates from the quarries in the Nantlle Valley to the port at Caernarfon from where they were exported. From Caernarfon to Llanwnda Station

4795-617: The Fifteen Tribes of Wales . The 400-year period following the collapse of Roman rule is the most difficult to interpret in the history of Wales. After the Roman departure in AD 410, much of the lowlands of Britain to the east and south-east was overrun by various Germanic peoples , commonly known as Anglo-Saxons. Some have theorized that the cultural dominance of the Anglo-Saxons was due to apartheid-like social conditions in which

4932-787: The Government of Wales Act 2006 such as health and education. Through this primary legislation, the Welsh Government can then also enact more specific subordinate legislation . Wales is served by four regional police forces: Dyfed-Powys Police , Gwent Police , North Wales Police , and South Wales Police . There are five prisons in Wales : four in the southern half of the country, and one in Wrexham . Wales has no women's prisons: female inmates are imprisoned in England. Wales

5069-558: The Normans . William I of England established a series of lordships, allocated to his most powerful warriors, along the Welsh border, their boundaries fixed only to the east (where they met other feudal properties inside England). Starting in the 1070s, these lords began conquering land in southern and eastern Wales, west of the River Wye . The frontier region, and any English-held lordships in Wales, became known as Marchia Wallie ,

5206-552: The Penmachno Document – and the rising of Llywelyn Bren (1316), the last uprising was led by Owain Glyndŵr , against Henry IV of England . In 1404, Owain was crowned prince of Wales in the presence of emissaries from France, Spain (Castille) and Scotland. Glyndŵr went on to hold parliamentary assemblies at several Welsh towns, including a Welsh parliament ( Welsh : senedd ) at Machynlleth . The rebellion

5343-665: The Second World War . The war saw Welsh servicemen and women fight in all major theatres, with some 15,000 of them killed. Bombing raids brought high loss of life as the German Air Force targeted the docks at Swansea , Cardiff and Pembroke . After 1943, 10 per cent of Welsh conscripts aged 18 were sent to work in the coal mines, where there were labour shortages; they became known as Bevin Boys . Pacifist numbers during both World Wars were fairly low, especially in

5480-456: The US EPA considers this region to extend much further offshore. "Coastal waters" has specific meanings in the context of commercial coastal shipping , and somewhat different meanings in the context of naval littoral warfare . Oceanographers and marine biologists have yet other takes. Coastal waters have a wide range of marine habitats from enclosed estuaries to the open waters of

5617-553: The United Kingdom  (green) Wales ( Welsh : Cymru [ˈkəmrɨ] ) is a country that is part of the United Kingdom . It is bordered by the Irish Sea to the north and west, England to the east , the Bristol Channel to the south, and the Celtic Sea to the south-west. As of 2021 , it had a population of 3.2 million. It has a total area of 21,218 square kilometres (8,192 sq mi) and over 2,700 kilometres (1,680 mi) of coastline . It

5754-617: The United Nations , about 44% of the human population lives within 150 km (93 mi) of the sea as of 2013 . Due to its importance in society and its high population concentrations, the coast is important for major parts of the global food and economic system, and they provide many ecosystem services to humankind. For example, important human activities happen in port cities. Coastal fisheries (commercial, recreational, and subsistence) and aquaculture are major economic activities and create jobs, livelihoods, and protein for

5891-686: The Welsh Marches , in which the Marcher lords were subject to neither English nor Welsh law . The extent of the March varied as the fortunes of the Marcher lords and the Welsh princes ebbed and flowed. Owain Gwynedd 's grandson Llywelyn Fawr (the Great, 1173–1240), received the fealty of other Welsh lords in 1216 at the council at Aberdyfi , becoming in effect the first prince of Wales . His grandson Llywelyn ap Gruffudd secured

6028-686: The Western Interior Seaway , a shallow sea that flooded central North America during the late Cretaceous Period (about 100 to 66 million years ago). These are beautifully exposed along the Book Cliffs of Utah and Colorado . The following articles describe the various geologic processes that affect a coastal zone: Larger animals that live in coastal areas include puffins , sea turtles and rockhopper penguins , among many others. Sea snails and various kinds of barnacles live on rocky coasts and scavenge on food deposited by

6165-469: The ocean and cause harmful effects there. The majority of this waste (80%) comes from land-based activity, although marine transportation significantly contributes as well. It is a combination of chemicals and trash, most of which comes from land sources and is washed or blown into the ocean. This pollution results in damage to the environment, to the health of all organisms, and to economic structures worldwide. Since most inputs come from land, either via

6302-596: The ocean . Floating oceanic debris tends to accumulate at the center of gyres and on coastlines, frequently washing aground, when it is known as beach litter or tidewrack. Deliberate disposal of wastes at sea is called ocean dumping . Naturally occurring debris, such as driftwood and drift seeds , are also present. With the increasing use of plastic , human influence has become an issue as many types of (petrochemical) plastics do not biodegrade quickly, as would natural or organic materials. The largest single type of plastic pollution (~10%) and majority of large plastic in

6439-444: The rivers , sewage or the atmosphere, it means that continental shelves are more vulnerable to pollution. Air pollution is also a contributing factor by carrying off iron, carbonic acid, nitrogen , silicon, sulfur, pesticides or dust particles into the ocean. The pollution often comes from nonpoint sources such as agricultural runoff , wind-blown debris , and dust. These nonpoint sources are largely due to runoff that enters

6576-567: The 18th century, lawyers, doctors, estate agents and government officials formed a bourgeoisie with sizeable houses. In the late 18th century, slate quarrying began to expand rapidly, most notably in North Wales. The Penrhyn quarry , opened in 1770 by Richard Pennant, 1st Baron Penrhyn , was employing 15,000 men by the late 19th century, and along with Dinorwic quarry , it dominated the Welsh slate trade. Although slate quarrying has been described as "the most Welsh of Welsh industries", it

6713-718: The Britons were at a disadvantage. By AD 500 the land that would become Wales had divided into a number of kingdoms free from Anglo-Saxon rule. The kingdoms of Gwynedd , Powys , Dyfed , Caredigion , Morgannwg , the Ystrad Tywi , and Gwent emerged as independent Welsh successor states . Archaeological evidence, in the Low Countries and what was to become England, shows early Anglo-Saxon migration to Great Britain reversed between 500 and 550, which concurs with Frankish chronicles. John Davies notes this as consistent with

6850-718: The Celtic languages arrived in Britain around 600 BCE. The Brythonic languages ceased to be spoken in England and were replaced by the English language, a Germanic language which arrived in Wales around the end of the eighth century due to the defeat of the Kingdom of Powys . The Bible translations into Welsh and the Protestant Reformation , which encouraged use of the vernacular in religious services, helped

6987-471: The Empire. Further Roman influence came through the spread of Christianity, which gained many followers when Christians were allowed to worship freely; state persecution ceased in the 4th century, as a result of Constantine the Great issuing an edict of toleration in 313. Early historians, including the 6th-century cleric Gildas , have noted 383 as a significant point in Welsh history. In that year,

7124-750: The English Crown, separate from England but under the same monarch. The king ruled directly in two areas: the Statute divided the north and delegated administrative duties to the Justice of Chester and Justiciar of North Wales , and further south in western Wales the King's authority was delegated to the Justiciar of South Wales . The existing royal lordships of Montgomery and Builth Wells remained unchanged. To maintain his dominance, Edward constructed

7261-773: The French use the term "Riviera" to refer to the Italian Riviera and call the French portion the "Côte d'Azur". As a result of the fame of the Ligurian rivieras, the term came into English to refer to any shoreline, especially one that is sunny, topographically diverse and popular with tourists. Such places using the term include the Australian Riviera in Queensland and the Turkish Riviera along

7398-693: The Late Bronze Age as part of a maritime trading-networked culture that included other Celtic nations . This "Atlantic-Celtic" view is opposed by others who hold that the Celtic languages derive their origins from the more easterly Hallstatt culture . By the time of the Roman invasion of Britain the area of modern Wales had been divided among the tribes of the Deceangli (north-east), Ordovices (north-west), Demetae (south-west), Silures (south-east), and Cornovii (east). The Roman conquest of Wales began in AD 48 and took 30 years to complete;

7535-800: The Lôn Eifion runs alongside that of the Welsh Highland Railway . At the Llanwnda station the Lon Eifion continues south over Glanrhyd to the A487/A499 Pwheli/Porthmadog roundabout, which prior to the Penygroes bypass , was the site of the old Llanwnda Rail Station on the Carnarvonshire Railway . Crossing the roundabout you join the Llanwnda - Groeslon section of the route Lon Eifion, passing on your right

7672-523: The National Assembly was renamed "Senedd Cymru" or "the Welsh Parliament", commonly known as the Senedd in both English and Welsh. Devolved areas of responsibility include agriculture, economic development, education, health, housing, local government, social services, tourism, transport and the Welsh language. The Welsh Government also promotes Welsh interests abroad. By tradition, Welsh Law

7809-608: The Norsemen occupying Northumbria to conquer the north. This alliance later broke down and Anarawd came to an agreement with Alfred , king of Wessex , with whom he fought against the west Welsh. According to Annales Cambriae , in 894, "Anarawd came with the Angles and laid waste to Ceredigion and Ystrad Tywi ." The southern and eastern parts of Great Britain lost to English settlement became known in Welsh as Lloegyr (Modern Welsh Lloegr ), which may have referred to

7946-659: The Roman general Magnus Maximus , or Macsen Wledig, stripped Britain of troops to launch a successful bid for imperial power, continuing to rule Britain from Gaul as emperor, and transferring power to local leaders. The earliest Welsh genealogies cite Maximus as the founder of several royal dynasties, and as the father of the Welsh Nation. He is given as the ancestor of a Welsh king on the Pillar of Eliseg , erected nearly 500 years after he left Britain, and he figures in lists of

8083-493: The Romans, Caerwent , is in south east Wales. Both Caerwent and Carmarthen , also in southern Wales, became Roman civitates . Wales had a rich mineral wealth. The Romans used their engineering technology to extract large amounts of gold, copper, and lead, as well as lesser amounts of zinc and silver. No significant industries were located in Wales in this time; this was largely a matter of circumstance as Wales had none of

8220-546: The Second World War, which was seen as a fight against fascism . Plaid Cymru was formed in 1925, seeking greater autonomy or independence from the rest of the UK. The term " England and Wales " became common for describing the area to which English law applied, and in 1955 Cardiff was proclaimed as Wales's capital. Cymdeithas yr Iaith Gymraeg (The Welsh Language Society) was formed in 1962, in response to fears that

8357-469: The UK government responsible for Wales, whose minister, the Secretary of State for Wales (Welsh secretary), sits in the UK cabinet . Wales has a devolved , unicameral legislature known as the Senedd (Senedd Cymru – Welsh Parliament) which holds devolved powers from the UK Parliament via a reserved powers model. For the purposes of local government , Wales has been divided into 22 council areas since 1996. These "principal areas" are responsible for

8494-426: The United Nations has declared 2021–2030 the UN Decade on Ecosystem Restoration , but restoration of coastal ecosystems has received insufficient attention. Since coasts are constantly changing, a coastline's exact perimeter cannot be determined; this measurement challenge is called the coastline paradox . The term coastal zone is used to refer to a region where interactions of sea and land processes occur. Both

8631-511: The agreement of king Elisedd ap Gwylog of Powys, as this boundary, extending north from the valley of the River Severn to the Dee estuary, gave him Oswestry . Another theory, after carbon dating placed the dyke's existence 300 years earlier, is that it was built by the post-Roman rulers of Wroxeter . King Offa of Mercia seems to have continued this initiative when he created a larger earthwork, now known as Offa's Dyke ( Clawdd Offa ). Davies wrote of Cyril Fox 's study of Offa's Dyke: "In

8768-571: The average sea level rose by 15–25 cm (6–10 in), with an increase of 2.3 mm (0.091 in) per year since the 1970s. This was faster than the sea level had ever risen over at least the past 3,000 years. The rate accelerated to 4.62 mm (0.182 in)/yr for the decade 2013–2022. Climate change due to human activities is the main cause. Between 1993 and 2018, melting ice sheets and glaciers accounted for 44% of sea level rise , with another 42% resulting from thermal expansion of water . International attention to address

8905-417: The average wind wave and swell conditions are relatively mild. Low energy coasts typically change slowly, and tend to be depositional environments. High energy coasts are exposed to the direct impact of waves and storms, and are generally erosional environments. High energy storm events can make large changes to a coastline, and can move significant amounts of sediment over a short period, sometimes changing

9042-413: The border. He ruled Wales with no internal battles. His territories were again divided into the traditional kingdoms. John Davies states that Gruffydd was "the only Welsh king ever to rule over the entire territory of Wales... Thus, from about 1057 until his death in 1063, the whole of Wales recognised the kingship of Gruffydd ap Llywelyn . For about seven brief years, Wales was one, under one ruler,

9179-461: The coast of Wales and other countries. Coastal fish , also called inshore fish or neritic fish, inhabit the sea between the shoreline and the edge of the continental shelf . Since the continental shelf is usually less than 200 metres (660 ft) deep, it follows that pelagic coastal fish are generally epipelagic fish , inhabiting the sunlit epipelagic zone . Coastal fish can be contrasted with oceanic fish or offshore fish , which inhabit

9316-812: The coast. Estuarine and marine coastal ecosystems are both marine ecosystems . Together, these ecosystems perform the four categories of ecosystem services in a variety of ways: The provisioning services include forest products, marine products, fresh water , raw materials, biochemical and genetic resources. Regulating services include carbon sequestration (contributing to climate change mitigation ) as well as waste treatment and disease regulation and buffer zones. Supporting services of coastal ecosystems include nutrient cycling , biologically mediated habitats and primary production . Cultural services of coastal ecosystems include inspirational aspects, recreation and tourism , science and education. According to one principle of classification, an emergent coastline

9453-567: The continental shelf. Similarly, the term littoral zone has no single definition. It is the part of a sea , lake , or river that is close to the shore . In coastal environments, the littoral zone extends from the high water mark , which is rarely inundated, to shoreline areas that are permanently submerged . Coastal waters can be threatened by coastal eutrophication and harmful algal blooms . The identification of bodies of rock formed from sediments deposited in shoreline and nearshore environments (shoreline and nearshore facies )

9590-481: The country from an agricultural society into an industrial one; the South Wales Coalfield 's exploitation caused a rapid expansion of Wales's population. Two-thirds of the population live in South Wales , including Cardiff, Swansea , Newport , and the nearby valleys . The eastern region of North Wales has about a sixth of the overall population, with Wrexham being the largest northern city. The remaining parts of Wales are sparsely populated . Since decline of

9727-432: The country's traditional extractive and heavy industries, the public sector , light and service industries, and tourism play major roles in its economy . Agriculture in Wales is largely livestock-based, making Wales a net exporter of animal produce, contributing towards national agricultural self-sufficiency . Both Welsh and English are official languages . A majority of the population of Wales speaks English. Welsh

9864-418: The creation of a Welsh assembly with an 80 per cent majority. In 1997, a second referendum on the same issue secured a very narrow majority (50.3 per cent). The National Assembly for Wales ( Cynulliad Cenedlaethol Cymru ) was set up in 1999 (under the Government of Wales Act 1998 ) with the power to determine how Wales's central government budget is spent and administered, although the UK Parliament reserved

10001-555: The deep seas beyond the continental shelves. Many coastal areas are famous for their kelp beds. Kelp is a fast-growing seaweed that can grow up to half a meter a day in ideal conditions. Mangroves , seagrasses , macroalgal beds, and salt marsh are important coastal vegetation types in tropical and temperate environments respectively. Restinga is another type of coastal vegetation. Coasts also face many human-induced environmental impacts and coastal development hazards . The most important ones are: The pollution of coastlines

10138-496: The dominant source of wealth. The emerging industrial period saw the development of copper smelting in the Swansea area. With access to local coal deposits and a harbour that connected it with Cornwall's copper mines in the south and the large copper deposits at Parys Mountain on Anglesey, Swansea developed into the world's major centre for non-ferrous metal smelting in the 19th century. The second metal industry to expand in Wales

10275-457: The end of the 1960s, the policy of bringing businesses into disadvantaged areas of Wales through financial incentives had proven very successful in diversifying the industrial economy. This policy, begun in 1934, was enhanced by the construction of industrial estates and improvements in transport communications, most notably the M4 motorway linking south Wales directly to London. It was believed that

10412-466: The first written evidence of the use of Cymru and y Cymry is found in a praise poem to Cadwallon ap Cadfan ( Moliant Cadwallon , by Afan Ferddig ) c.  633 . In Armes Prydein , believed to be written around 930–942, the words Cymry and Cymro are used as often as 15 times. However, from the Anglo-Saxon settlement onwards, the people gradually begin to adopt

10549-450: The forests to establish pasture and to cultivate the land, developed new technologies such as ceramics and textile production, and built cromlechs such as Pentre Ifan , Bryn Celli Ddu , and Parc Cwm long cairn between about 5,800 BP and 5,500 BP. Over the following centuries they assimilated immigrants and adopted ideas from Bronze Age and Iron Age Celtic cultures. Some historians, such as John T. Koch , consider Wales in

10686-452: The foundations for stable economic growth had been firmly established in Wales during this period, but this was shown to be optimistic after the recession of the early 1980s saw the collapse of much of the manufacturing base that had been built over the preceding forty years. The Welsh Language Act 1967 repealed a section of the Wales and Berwick Act and thus "Wales" was no longer part of

10823-751: The highest court of first instance as well as an appellate court . The three divisions are the Court of Appeal , the High Court of Justice , and the Crown Court . Minor cases are heard by magistrates' courts or the County Court . In 2007 the Wales and Cheshire Region (known as the Wales and Cheshire Circuit before 2005) came to an end when Cheshire was attached to the North-Western England Region. From that point, Wales became

10960-789: The human uses of the coast and threaten coastal ecosystems. The interactive effects of climate change, habitat destruction , overfishing , and water pollution (especially eutrophication ) have led to the demise of coastal ecosystem around the globe. This has resulted in population collapse of fisheries stocks, loss of biodiversity , increased invasion of alien species , and loss of healthy habitats. International attention to these issues has been captured in Sustainable Development Goal 14 "Life Below Water", which sets goals for international policy focused on preserving marine coastal ecosystems and supporting more sustainable economic practices for coastal communities. Likewise,

11097-481: The increased diversity of the Welsh economy. Population growth however outpaced economic growth and the standard of living dropped. Prior to the Industrial Revolution in Wales , there were small-scale industries scattered throughout Wales. These ranged from those connected to agriculture, such as milling and the manufacture of woollen textiles , through to mining and quarrying. Agriculture remained

11234-587: The intention of recognizing that the River Wye and its traffic belonged to the kingdom of Gwent." However, Fox's interpretations of both the length and purpose of the Dyke have been questioned by more recent research. In 853, the Vikings raided Anglesey , but in 856, Rhodri Mawr defeated and killed their leader, Gorm. The Celtic Britons of Wales made peace with the Vikings and Anarawd ap Rhodri allied with

11371-532: The kingdom of Mercia originally and which came to refer to England as a whole. The Germanic tribes who now dominated these lands were invariably called Saeson , meaning " Saxons ". The Anglo-Saxons called the Romano-British * Walha , meaning 'Romanised foreigner' or 'stranger'. The Welsh continued to call themselves Brythoniaid (Brythons or Britons) well into the Middle Ages , though

11508-463: The language might soon die out. Nationalist sentiment grew following the flooding of the Tryweryn valley in 1965 to create a reservoir to supply water to the English city of Liverpool . Although 35 of the 36 Welsh MPs voted against the bill (one abstained), Parliament passed the bill and the village of Capel Celyn was submerged, highlighting Wales's powerlessness in her own affairs in the face of

11645-419: The language survive after Welsh elites abandoned it in favour of English in the fifteenth and sixteenth centuries. Successive Welsh Language Acts, in 1942, 1967 and 1993 , improved the legal status of Welsh. The Welsh Language (Wales) Measure 2011 modernised the 1993 Welsh Language Act and gave Welsh an official status in Wales for the first time, a major landmark for the language. The Measure also created

11782-583: The large number English people living in Wales. After the Senedd and Elections (Wales) Act 2020 , the National Assembly was renamed " Senedd Cymru " in Welsh and the "Welsh Parliament" in English, which was seen as a better reflection of the body's expanded legislative powers. The Welsh language ( Welsh : Cymraeg ) is an Indo-European language of the Celtic family ; the most closely related languages are Cornish and Breton . Most linguists believe that

11919-507: The law making powers of the National Assembly it is now able to make laws, known as Acts of the Assembly, on all matters in devolved subject areas, without needing the UK Parliament's agreement. In the 2016 referendum , Wales voted in support of leaving the European Union, although demographic differences became evident. According to Danny Dorling , professor of geography at Oxford University, votes for Leave may have been boosted by

12056-624: The legal definition of England. This essentially defined Wales as a separate entity legally (but within the UK), for the first time since before the Laws in Wales Acts 1535 and 1542 which defined Wales as a part of the Kingdom of England. The Welsh Language Act 1967 also expanded areas where use of Welsh was permitted, including in some legal situations. In a referendum in 1979 , Wales voted against

12193-462: The legal system of England and Wales since 1536. English law is regarded as a common law system, with no major codification of the law and legal precedents are binding as opposed to persuasive. The court system is headed by the Supreme Court of the United Kingdom which is the highest court of appeal in the land for criminal and civil cases. The Senior Courts of England and Wales is

12330-410: The majority of coastal human populations. Other coastal spaces like beaches and seaside resorts generate large revenues through tourism . Marine coastal ecosystems can also provide protection against sea level rise and tsunamis . In many countries, mangroves are the primary source of wood for fuel (e.g. charcoal ) and building material. Coastal ecosystems like mangroves and seagrasses have

12467-594: The male population. Of these, roughly 35,000 were killed, with particularly heavy losses of Welsh forces at Mametz Wood on the Somme and the Battle of Passchendaele . The first quarter of the 20th century also saw a shift in the political landscape of Wales. Since 1865, the Liberal Party had held a parliamentary majority in Wales and, following the general election of 1906 , only one non-Liberal Member of Parliament, Keir Hardie of Merthyr Tydfil , represented

12604-673: The margins of the continental shelves , make up about 7 percent of the Earth's oceans, but at least 85% of commercially harvested fish depend on coastal environments during at least part of their life cycle. As of October 2010, about 2.86% of exclusive economic zones were part of marine protected areas . The definition of coasts varies. Marine scientists think of the "wet" (aquatic or intertidal ) vegetated habitats as being coastal ecosystems (including seagrass, salt marsh etc.) whilst some terrestrial scientists might only think of coastal ecosystems as purely terrestrial plants that live close to

12741-587: The microplastics go through the water filtration system and into the ocean, but because of their small size they are likely to escape capture by the preliminary treatment screens on wastewater plants. These beads are harmful to the organisms in the ocean, especially filter feeders, because they can easily ingest the plastic and become sick. The microplastics are such a concern because it is difficult to clean them up due to their size, so humans can try to avoid using these harmful plastics by purchasing products that use environmentally safe exfoliates. Between 1901 and 2018,

12878-507: The more resistant rocks erode more slowly, remaining as headlands or outcroppings . Parts of a coastline can be categorised as high energy coast or low energy coast. The distinguishing characteristics of a high energy coast are that the average wave energy is relatively high so that erosion of small grained material tends to exceed deposition, and consequently landforms like cliffs, headlands and wave-cut terraces develop. Low energy coasts are generally sheltered from waves, or in regions where

13015-480: The name Cymry over Brythoniad . From 800 onwards, a series of dynastic marriages led to Rhodri Mawr 's ( r. 844–77) inheritance of Gwynedd and Powys . His sons founded the three dynasties of Aberffraw for Gwynedd , Dinefwr for Deheubarth and Mathrafal for Powys . Rhodri 's grandson Hywel Dda (r. 900–50) founded Deheubarth out of his maternal and paternal inheritances of Dyfed and Seisyllwg in 930, ousted

13152-1072: The name of the Gauls known to the Romans as Volcae . This term was later used to refer indiscriminately to inhabitants of the Western Roman Empire . Anglo-Saxons came to use the term to refer to the Britons in particular; the plural form Wēalas evolved into the name for their territory, Wales. Historically in Britain , the words were not restricted to modern Wales or to the Welsh but were used to refer to anything that Anglo-Saxons associated with Britons, including other non-Germanic territories in Britain (e.g. Cornwall ) and places in Anglo-Saxon territory associated with Britons (e.g. Walworth in County Durham and Walton in West Yorkshire). The modern Welsh name for themselves

13289-476: The necessary materials in suitable combination, and the forested, mountainous countryside was not amenable to industrialisation. Latin became the official language of Wales, though the people continued to speak in Brythonic. While Romanisation was far from complete, the upper classes came to consider themselves Roman, particularly after the ruling of 212 that granted Roman citizenship to all free men throughout

13426-568: The numerical superiority of English MPs in Parliament. Separatist groupings, such as the Free Wales Army and Mudiad Amddiffyn Cymru were formed, conducting campaigns from 1963. Prior to the investiture of Charles in 1969, these groups were responsible for a number of bomb attacks on infrastructure. At a by-election in 1966, Gwynfor Evans won the parliamentary seat of Carmarthen , Plaid Cymru's first Parliamentary seat. By

13563-625: The occupation lasted over 300 years. The campaigns of conquest were opposed by two native tribes: the Silures and the Ordovices . Caractacus or Caradog , leader of the Ordovices, had initial success in resisting Roman invasions of north Wales but was eventually defeated. Roman rule in Wales was a military occupation, save for the southern coastal region of south Wales , where there is a legacy of Romanisation. The only town in Wales founded by

13700-441: The ocean through rivers, but wind-blown debris and dust can also play a role, as these pollutants can settle into waterways and oceans. Pathways of pollution include direct discharge, land runoff, ship pollution , bilge pollution , atmospheric pollution and, potentially, deep sea mining . Marine debris , also known as marine litter, is human-created solid material that has deliberately or accidentally been released in seas or

13837-485: The oceans is discarded and lost nets from the fishing industry. Waterborne plastic poses a serious threat to fish , seabirds , marine reptiles , and marine mammals , as well as to boats and coasts. A growing concern regarding plastic pollution in the marine ecosystem is the use of microplastics. Microplastics are beads of plastic less than 5 millimeters wide, and they are commonly found in hand soaps, face cleansers, and other exfoliators. When these products are used,

13974-531: The old railway line through trees and farm land down to Bryncir . At Bryncir the cycle route deviates from the old railway line and heads westerly and steeply upward through a farm and on to single track road before heading south again into Cricceith. Walkers can take the Lôn Goed path from near Bryncir to the coast at Afon Wen . Wales – in Europe  (green & dark grey) – in

14111-537: The planning of it, there was a degree of consultation with the kings of Powys and Gwent. On the Long Mountain near Trelystan , the dyke veers to the east, leaving the fertile slopes in the hands of the Welsh; near Rhiwabon , it was designed to ensure that Cadell ap Brochwel retained possession of the Fortress of Penygadden." And, for Gwent, Offa had the dyke built "on the eastern crest of the gorge, clearly with

14248-743: The post of Welsh Language Commissioner , replacing the Welsh Language Board. Following the referendum in 2011, the Official Languages Act became the first Welsh law to be created in 600 years, according to the First Minister at the time, Carwyn Jones . This law was passed by Welsh Assembly members (AMs) only and made Welsh an official language of the National Assembly. Starting in the 1960s, many road signs have been replaced by bilingual versions. Various public and private sector bodies have adopted bilingualism to

14385-526: The provision of all local government services. Following devolution in 1997, the Government of Wales Act 1998 created a Welsh devolved assembly, the National Assembly for Wales , with the power to determine how Wales's central government budget is spent and administered. Eight years later, the Government of Wales Act 2006 reformed the National Assembly for Wales and allowed further powers to be granted to it more easily. The Act also created

14522-657: The railway cottages built to serve the railway station. The route continues alongside the A487 before passing underneath the road bridge at Afon Llifon before continuing to the village of Groeslon . Crossing the road at the Tafarn Pennionyn the Lon Eifion continues on the East side of the A487 until crossing over again via a foot bridge. Once over the foot bridge the Lon Eifon cuts through woodland heading due South, passing

14659-485: The rear of Inigo Jones Slate Works and further on to open field land with views to the West of Pontllyfni and Aberdasach and The Rivals until reaching another footbridge at the end of Clynogg Road and continuing down to the roundabout of A487/B4418. Continuing south the Lon Eifion continues to closely follow the A487 until vearing away and more South Westerly at Nebo. It continues on a much quieter and greener route along

14796-475: The recognition of the title Prince of Wales from Henry III with the Treaty of Montgomery in 1267. Subsequent disputes, including the imprisonment of Llywelyn 's wife Eleanor , culminated in the first invasion by King Edward I of England . As a result of military defeat, the Treaty of Aberconwy exacted Llywelyn 's fealty to England in 1277. Peace was short-lived, and, with the 1282 Edwardian conquest ,

14933-406: The right to set limits on its powers. The Government of Wales Act 2006 (c 32) is an Act of the Parliament of the United Kingdom that reformed the National Assembly for Wales and allows further powers to be granted to it more easily. The Act creates a system of government with a separate executive drawn from and accountable to the legislature. Following a successful referendum in 2011 on extending

15070-399: The rule of the Welsh princes permanently ended. With Llywelyn 's death and his brother prince Dafydd 's execution, the few remaining Welsh lords did homage to Edward I of England . The Statute of Rhuddlan in 1284 provided the constitutional basis for a post-conquest government of the Principality of North Wales from 1284 until 1535/36. It defined Wales as "annexed and united" to

15207-611: The ruler. Other than in the Marches , where March law was imposed by the Marcher Lords, Welsh Law remained in force in Wales until the Statute of Rhuddlan in 1284. Edward I of England annexed the Principality of Wales following the death of Llywelyn ap Gruffudd , and Welsh Law was replaced for criminal cases under the Statute. Marcher Law and Welsh Law (for civil cases) remained in force until Henry VIII of England annexed

15344-416: The sandstone is coarser than the lower part (a coarsening upwards sequence ). Geologists refer to these are parasequences . Each records an episode of retreat of the ocean from the shoreline over a period of 10,000 to 1,000,000 years. These often show laminations reflecting various kinds of tidal cycles. Some of the best-studied shoreline deposits in the world are found along the former western shore of

15481-579: The sea. Some coastal animals are used to humans in developed areas, such as dolphins and seagulls who eat food thrown for them by tourists. Since the coastal areas are all part of the littoral zone , there is a profusion of marine life found just off-coast, including sessile animals such as corals , sponges, starfish, mussels, seaweeds, fishes, and sea anemones . There are many kinds of seabirds on various coasts. These include pelicans and cormorants , who join up with terns and oystercatchers to forage for fish and shellfish. There are sea lions on

15618-401: The seashore (see also estuaries and coastal ecosystems ). While there is general agreement in the scientific community regarding the definition of coast, in the political sphere, the delineation of the extents of a coast differ according to jurisdiction . Government authorities in various countries may define coast differently for economic and social policy reasons. The coastline paradox

15755-427: The second principle of classification, a concordant coastline is a coastline where bands of different rock types run parallel to the shore. These rock types are usually of varying resistance , so the coastline forms distinctive landforms, such as coves. Discordant coastlines feature distinctive landforms because the rocks are eroded by the ocean waves . The less resistant rocks erode faster, creating inlets or bay ;

15892-404: The slope than up it. Steep waves that are close together and break with the surf plunging down onto the shore slope expend much of their energy lifting the sediment. The weak swash does not carry it far up the slope, and the strong backwash carries it further down the slope, where it either settles in deeper water or is carried along the shore by a longshore current induced by an angled approach of

16029-551: The story of Cantre'r Gwaelod 's drowning and tales in the Mabinogion , of the waters between Wales and Ireland being narrower and shallower, may be distant folk memories of this time. Neolithic colonists integrated with the indigenous people, gradually changing their lifestyles from a nomadic life of hunting and gathering, to become settled farmers about 6,000 BP – the Neolithic Revolution . They cleared

16166-758: The terms coast and coastal are often used to describe a geographic location or region located on a coastline (e.g., New Zealand's West Coast , or the East , West , and Gulf Coast of the United States .) Coasts with a narrow continental shelf that are close to the open ocean are called pelagic coast , while other coasts are more sheltered coast in a gulf or bay . A shore , on the other hand, may refer to parts of land adjoining any large body of water, including oceans (sea shore) and lakes (lake shore). The Earth has approximately 620,000 kilometres (390,000 mi) of coastline. Coastal habitats, which extend to

16303-425: The then Counsel General for Wales , John Griffiths , stated, 'Principality is a misnomer and that Wales should properly be referred to as a country.' In 2011, ISO 3166-2:GB was updated and the term 'principality' was replaced with 'country'. UK Government toponymic guidelines state that, 'though there is a Prince of Wales, this role is deemed to be titular rather than exerting executive authority, and therefore Wales

16440-444: The throne of England from Richard III of England in 1485, uniting England and Wales under one royal house. The last remnants of Celtic-tradition Welsh law were abolished and replaced by English law by the Laws in Wales Acts 1535 and 1542 during the reign of Henry VII's son, Henry VIII . In the legal jurisdiction of England and Wales , Wales became unified with the kingdom of England; the " Principality of Wales " began to refer to

16577-487: The wave the more energy it releases and the more sediment it moves. Coastlines with longer shores have more room for the waves to disperse their energy, while coasts with cliffs and short shore faces give little room for the wave energy to be dispersed. In these areas, the wave energy breaking against the cliffs is higher, and air and water are compressed into cracks in the rock, forcing the rock apart, breaking it down. Sediment deposited by waves comes from eroded cliff faces and

16714-476: The wave-front to the shore. These waves which erode the beach are called destructive waves. Low waves that are further apart and break by spilling , expend more of their energy in the swash which carries particles up the beach, leaving less energy for the backwash to transport them downslope, with a net constrictive influence on the beach. Riviera is an Italian word for "shoreline", ultimately derived from Latin ripa ("riverbank"). It came to be applied as

16851-407: The waves surge up the river estuaries from the ocean. Geologists classify coasts on the basis of tidal range into macrotidal coasts with a tidal range greater than 4 m (13 ft); mesotidal coasts with a tidal range of 2 to 4 m (6.6 to 13 ft); and microtidal coasts with a tidal range of less than 2 m (7 ft). The distinction between macrotidal and mesotidal coasts

16988-504: The whole country, though it remained a "principality" only in a ceremonial sense. The Marcher lordships were abolished, and Wales began electing members of the Westminster parliament. In 1536 Wales had around 278,000 inhabitants, which increased to around 360,000 by 1620. This was primarily due to rural settlement, where animal farming was central to the Welsh economy. Increase in trade and increased economic stability occurred due to

17125-469: The whole ocean system are ultimately connected, although certain regional classifications are useful and relevant. The waters of the continental shelves represent such a region. The term "coastal waters" has been used in a wide variety of different ways in different contexts. In European Union environmental management it extends from the coast to just a few nautical miles while in the United States

17262-576: The whole of Wales under the Laws in Wales Acts 1535 and 1542 (often referred to as the Acts of Union of 1536 and 1543), after which English law applied to the whole of Wales. The Wales and Berwick Act 1746 provided that all laws that applied to England would automatically apply to Wales (and the Anglo-Scottish border town of Berwick ) unless the law explicitly stated otherwise; this Act was repealed with regard to Wales in 1967. English law has been

17399-482: The world's people live in coastal regions. According to a United Nations atlas, 44% of all people live within 150 km (93 mi) of the sea. Many major cities are on or near good harbors and have port facilities. Some landlocked places have achieved port status by building canals . Nations defend their coasts against military invaders, smugglers and illegal migrants. Fixed coastal defenses have long been erected in many nations, and coastal countries typically have

17536-532: Was annexed by England and incorporated within the English legal system under the Laws in Wales Acts 1535 and 1542 . Distinctive Welsh politics developed in the 19th century. Welsh Liberalism , exemplified in the early 20th century by David Lloyd George , was displaced by the growth of socialism and the Labour Party . Welsh national feeling grew over the century: a nationalist party, Plaid Cymru ,

17673-576: Was a key factor in destroying support for the Liberal party in south Wales. The industrial workers of Wales began shifting towards the Labour Party . When in 1908 the Miners' Federation of Great Britain became affiliated to the Labour Party, the four Labour candidates sponsored by miners were all elected as MPs. By 1922, half the Welsh seats at Westminster were held by Labour politicians—the start of

17810-467: Was briefly united under Gruffydd ap Llywelyn in 1055. After over 200 years of war, the conquest of Wales by King Edward I of England was completed by 1283, though Owain Glyndŵr led the Welsh Revolt against English rule in the early 15th century, and briefly re-established an independent Welsh state with its own national parliament ( Welsh : senedd ). In the 16th century the whole of Wales

17947-437: Was compiled during an assembly held at Whitland around 930 by Hywel Dda , king of most of Wales between 942 and his death in 950. The ' law of Hywel Dda ' ( Welsh : Cyfraith Hywel ), as it became known, codified the previously existing folk laws and legal customs that had evolved in Wales over centuries. Welsh Law emphasised the payment of compensation for a crime to the victim, or the victim's kin, rather than punishment by

18084-442: Was eventually defeated by 1412. Having failed Owain went into hiding and nothing was known of him after 1413. The penal laws against the Welsh of 1401–02 passed by the English parliament made the Welsh second-class citizens. With hopes of independence ended, there were no further wars or rebellions against English colonial rule and the laws remained on the statute books until 1624. Henry Tudor (born in Wales in 1457) seized

18221-441: Was expanded upon by Benoit Mandelbrot . Tides often determine the range over which sediment is deposited or eroded. Areas with high tidal ranges allow waves to reach farther up the shore, and areas with lower tidal ranges produce deposition at a smaller elevation interval. The tidal range is influenced by the size and shape of the coastline. Tides do not typically cause erosion by themselves; however, tidal bores can erode as

18358-556: Was formed in 1925, and the Welsh Language Society in 1962. A governing system of Welsh devolution is employed in Wales, of which the most major step was the formation of the Senedd (Welsh Parliament, formerly the National Assembly for Wales) in 1998, responsible for a range of devolved policy matters . At the dawn of the Industrial Revolution , development of the mining and metallurgical industries transformed

18495-577: Was free of glaciers by about 10,250 BP, the warmer climate allowing the area to become heavily wooded. The post-glacial rise in sea level separated Wales and Ireland, forming the Irish Sea . By 8,000 BP the British Peninsula had become an island. By the beginning of the Neolithic ( c.  6,000 BP ) sea levels in the Bristol Channel were still about 33 feet (10 metres) lower than today. The historian John Davies theorised that

18632-436: Was iron smelting, and iron manufacturing became prevalent in both the north and the south of the country. In the north, John Wilkinson 's Ironworks at Bersham was a major centre, while in the south, at Merthyr Tydfil , the ironworks of Dowlais , Cyfarthfa , Plymouth and Penydarren became the most significant hub of iron manufacture in Wales. By the 1820s, south Wales produced 40 per cent of all Britain's pig iron . By

18769-573: Was producing almost 61 million tons of coal. Historian Kenneth Morgan described Wales on the eve of the First World War as a "relatively placid, self-confident and successful nation". The output from the coalfields continued to increase, with the Rhondda Valley recording a peak of 9.6 million tons of coal extracted in 1913. The First World War (1914–1918) saw a total of 272,924 Welshmen under arms, representing 21.5 per cent of
