Creaghan and O'Creaghan are a mix of the English language and the Irish language . Cryan is another variant of the name. An early reference to the name is in the Annals of the Four Masters which was written between 1632 and 1636, and which says that Murrough O'Creaghan, Lord of Hy Fiachrach
222-744: A three-year guerrilla war , which ended in a truce in July 1921 (although violence continued until June 1922, mostly in Northern Ireland). In December 1921, the Anglo-Irish Treaty was concluded between the British government and representatives of the Second Dáil . It gave Ireland complete independence in its home affairs and practical independence for foreign policy, but an opt-out clause allowed Northern Ireland to remain within

A 16th century manuscript, A Description of Ireland as it is in hoc anno 1598 , describes a John O'Crean who was head of his house or town of Bellanagare , which was then within the boundaries of County Sligo. According to the same manuscript, the head of the family in the 16th century was O'Crean of Annagh. James Crean

To prevent this from happening, the Ulster Volunteers were formed in 1913 under the leadership of Edward Carson . Their formation was followed in 1914 by the establishment of the Irish Volunteers , whose aim was to ensure that the Home Rule Bill was passed. The Act was passed but with the "temporary" exclusion of

Much of Ireland was woodland until the end of the Middle Ages . Today, woodland makes up about 10% of the island, compared with a European average of over 33%, with most of it being non-native conifer plantations. The Irish climate

The most recent genetic research strongly associates the spread of Indo-European languages (including Celtic) through Western Europe with a people bringing a composite Beaker culture , with its arrival in Britain and Ireland dated to around the middle of the third millennium BC. According to John T. Koch and others, Ireland in

One mile is 5280 feet (1760 yards). In western Canada and the western United States, divisions of land area were typically based on the square mile, and fractions thereof. If the square mile is divided into quarters, each quarter has

999-630: A goddess in Irish mythology first recorded in the ninth century. The etymology of Ériu is disputed but may derive from the Proto-Indo-European root * h2uer , referring to flowing water. During the last glacial period , and until about 16,000 BC, much of Ireland was periodically covered in ice. The relative sea level was less than 50m lower resulting in an ice bridge (but not a land bridge ) forming between Ireland and Great Britain. By 14,000 BC this ice bridge existed only between Northern Ireland and Scotland and by 12,000 BC Ireland
1110-826: A minor sept of the Cenél nEógain in Donegal which had a branch in the neighboring County Sligo . Historian C. Thomas Cairney also stated that the O'Creans, Crehans and Creghans were a sept of the Cenél nEógain from Donegal and who later moved to Sligo. The Creaghs were a separate family who were originally from the clan called the Dalcassians of the 10th century in County Clare and who later became merchants in Limerick and Cork , as well as producing several churchmen in

Ptolemy in his Almagest refers to Ireland as Mikra Brettania ("Little Britain"), in contrast to the larger island, which he called Megale Brettania ("Great Britain"). In his map of Ireland in his later work, Geography , Ptolemy refers to Ireland as Iouernia and to Great Britain as Albion . These 'new' names were likely to have been

Ireland did have a culturally unifying rule of law: the early written judicial system, the Brehon Laws , administered by a professional class of jurists known as the brehons . The Chronicle of Ireland records that in 431, Bishop Palladius arrived in Ireland on a mission from Pope Celestine I to minister to

Despite assistance from France the rebellion was put down by British and Irish government and yeomanry forces. The rebellion lasted from the 24th of May to the 12th of October that year and saw the establishment of the short lived Irish Republic (1798) in the province on Connacht . It saw numerous battles across

Field systems were developed in different parts of Ireland, including at the Céide Fields , that has been preserved beneath a blanket of peat in present-day Tyrawley . An extensive field system , arguably the oldest in the world, consisted of small divisions separated by dry-stone walls . The fields were farmed for several centuries between 3,500 BC and 3,000 BC. Wheat and barley were

These subunits are typically then again divided into quarters, with each side being 1 ⁄ 4 mile long, and being 1 ⁄ 16 of a square mile in area, or 40 acres. In the United States, farmland was typically divided as such, and the phrase "the back 40" refers to the 40-acre parcel to
1887-462: A side. As a unit of measure, an acre has no prescribed shape; any area of 43,560 square feet is an acre. In the international yard and pound agreement of 1959, the United States and five countries of the Commonwealth of Nations defined the international yard to be exactly 0.9144 metre. The US authorities decided that, while the refined definition would apply nationally in all other respects,
1998-674: A sovereign state covering five-sixths of the island, and Northern Ireland , which is part of the United Kingdom . As of 2022, the population of the entire island is just over 7 million, with 5.1 million in the Republic of Ireland and 1.9 million in Northern Ireland, ranking it the second-most populous island in Europe after Great Britain. The geography of Ireland comprises relatively low-lying mountains surrounding
2109-573: A yard are used (see survey foot and survey yard ), so the exact size of an acre depends upon the yard upon which it is based. The US survey acre is about 4,046.872 square metres; its exact value ( 4046 + 13,525,426 / 15,499,969 m ) is based on an inch defined by 1 metre = 39.37 inches exactly, as established by the Mendenhall Order of 1893. Surveyors in the United States use both international and survey feet, and consequently, both varieties of acre. Since

Historical linguists are skeptical that this method alone could account for the absorption of Celtic language, with some saying that an assumed processual view of Celtic linguistic formation is 'an especially hazardous exercise'. Genetic lineage investigation into the area of Celtic migration to Ireland has led to findings that showed no significant differences in mitochondrial DNA between Ireland and large areas of continental Europe, in contrast to parts of

This defined the Anglo-Norman administration in Ireland as the Lordship of Ireland . When Henry's successor died unexpectedly in 1199, John inherited the crown of England and retained the Lordship of Ireland. Over the century that followed, Norman feudal law gradually replaced

Rainfall and cloud cover are abundant. Gaelic Ireland had emerged by the 1st century AD. The island was Christianised from the 5th century onwards. During this period Ireland was divided into many petty kingships under provincial kingships (Cúige "fifth" of

While all modern variants of the acre contain 4,840 square yards, there are alternative definitions of a yard, so the exact size of an acre depends upon the particular yard on which it is based. Originally, an acre

Traditionally, in the Middle Ages , an acre was conceived of as the area of land that could be ploughed by one man using a team of eight oxen in one day. The acre is still a statutory measure in the United States. Both the international acre and the US survey acre are in use, but they differ by only four parts per million (see below).

Ireland continued as a patchwork of rival kingdoms; however, beginning in the 7th century, a concept of national kingship gradually became articulated through the concept of a High King of Ireland . Medieval Irish literature portrays an almost unbroken sequence of high kings stretching back thousands of years, but some modern historians believe
3330-686: The Lebor Gabála Érenn , a medieval Christian pseudo-history of Ireland, along with the presence of Celtic culture, language and artefacts found in Ireland such as Celtic bronze spears, shields, torcs and other finely crafted Celtic associated possessions. The theory holds that there were four separate Celtic invasions of Ireland. The Priteni were said to be the first, followed by the Belgae from northern Gaul and Britain. Later, Laighin tribes from Armorica (present-day Brittany) were said to have invaded Ireland and Britain more or less simultaneously. Lastly,

Northern Ireland was granted a limited special status and allowed to operate within the EU single market for goods without being in
3774-549: The Irish parliament passed the Statutes of Kilkenny in 1367. These were a set of laws designed to prevent the assimilation of the Normans into Irish society by requiring English subjects in Ireland to speak English, follow English customs and abide by English law. By the end of the 15th century, central English authority in Ireland had all but disappeared, and a renewed Irish culture and language, albeit with Norman influences,
3885-596: The Milesians ( Gaels ) were said to have reached Ireland from either northern Iberia or southern Gaul. It was claimed that a second wave named the Euerni, belonging to the Belgae people of northern Gaul, began arriving about the sixth century BC. They were said to have given their name to the island. The theory was advanced in part because of the lack of archaeological evidence for large-scale Celtic immigration, though it

The winters destroyed stored crops of potatoes and other staples, and the poor summers severely damaged harvests. This resulted in the famine of 1740 . An estimated 250,000 people (about one in eight of the population) died from

The Vikings were involved in establishing most of the major coastal settlements in Ireland: Dublin , Limerick , Cork , Wexford , Waterford , as well as other smaller settlements. On 1 May 1169, an expedition of Cambro-Norman knights, with an army of about 600 men, landed at Bannow Strand in present-day County Wexford . It

Statutory values for the acre were enacted in England, and subsequently the United Kingdom, by acts of: Historically, the size of farms and landed estates in the United Kingdom was usually expressed in acres (or acres, roods , and perches ), even if the number of acres was so large that it might conveniently have been expressed in square miles. For example,

From the mid-14th century, after the Black Death , Norman settlements in Ireland went into a period of decline. The Norman rulers and the Gaelic Irish elites intermarried and the areas under Norman rule became Gaelicised . In some parts, a hybrid Hiberno-Norman culture emerged. In response,

The Easter Rising of 1916 was carried out by the latter group together with a smaller socialist militia, the Irish Citizen Army . The British response, executing fifteen leaders of the Rising over a period of ten days and imprisoning or interning more than a thousand people, turned the mood of the country in favour of the rebels. Support for Irish republicanism increased further due to

This contrasts with the traditional view that their origin lies in mainland Europe with the Hallstatt culture . The long-standing traditional view is that the Celtic language, Ogham script and culture were brought to Ireland by waves of invading or migrating Celts from mainland Europe. This theory draws on

The document apparently encouraged Henry to take control in Ireland in order to oversee the financial and administrative reorganisation of the Irish Church and its integration into the Roman Church system. Some restructuring had already begun at the ecclesiastical level following the Synod of Kells in 1152. There has been significant controversy regarding

In 1172, Pope Alexander III further encouraged Henry to advance the integration of the Irish Church with Rome. Henry was authorised to impose a tithe of one penny per hearth as an annual contribution. This church levy, called Peter's Pence ,

Additional regressive punitive legislation followed in 1703, 1709 and 1728. This completed a comprehensive systemic effort to materially disadvantage Roman Catholics and Protestant Dissenters while enriching a new ruling class of Anglican conformists. The new Anglo-Irish ruling class became known as

Some time before 4,000 BC, Neolithic settlers introduced cereal cultivars , domesticated animals such as cattle and sheep, built large timber buildings, and stone monuments. The earliest evidence for farming in Ireland or Great Britain is from Ferriter's Cove , County Kerry , where a flint knife, cattle bones and

The passage of the Act in the Irish Parliament was ultimately achieved with substantial majorities, having failed on
8325-610: The latter part of this century and the architectural legacy of Georgian Ireland was built. In 1782, Poynings' Law was repealed, giving Ireland legislative independence from Great Britain for the first time since 1495.

In 1798, members of the Protestant Dissenter tradition (mainly Presbyterian ) made common cause with Roman Catholics in
8436-482: The local names for the islands at the time. The earlier names, in contrast , were likely to have been coined before direct contact with local peoples was made.

The relationship between the Roman Empire and the kingdoms of ancient Ireland
8547-608: The many carved stone crosses that still dot the island today. A mission founded in 563 on Iona by the Irish monk Saint Columba began a tradition of Irish missionary work that spread Celtic Christianity and learning to Scotland , England and the Frankish Empire on continental Europe after the fall of Rome. These missions continued until the late Middle Ages , establishing monasteries and centres of learning, producing scholars such as Sedulius Scottus and Johannes Eriugena and exerting much influence in Europe. From

The population has never returned to this level since. The population continued to fall until 1961; County Leitrim was the final Irish county to record a population increase post-famine, in 2006. The 19th and early 20th centuries saw
8991-530: The potential defence of Northern Ireland. Despite their country's neutrality, approximately 50,000 volunteers from independent Ireland joined the British forces during the war, four being awarded Victoria Crosses . The German intelligence was also active in Ireland. Its operations ended in September 1941 when police made arrests based on surveillance carried out on the key diplomatic legations in Dublin. To
9102-436: The principal crops. The Bronze Age began around 2,500 BC, with technology changing people's everyday lives during this period through innovations such as the wheel, harnessing oxen , weaving textiles , brewing alcohol and metalworking , which produced new weapons and tools, along with fine gold decoration and jewellery, such as brooches and torcs . How and when the island became Celtic has been debated for close to
9213-610: The rise of modern Irish nationalism , primarily among the Roman Catholic population. The pre-eminent Irish political figure after the Union was Daniel O'Connell .

After the rising had been suppressed, Andrew Crean and his wife, Agnes French, were transplanted from Annagh in County Sligo and were compensated with 600 acres in Annagh in County Mayo . A Julian Crean is recorded with them who jointly received 634 acres. During the Irish Confederate Wars in 1645, parliamentary forces under Charles Coote from Ulster attacked Sligo which
9435-489: The scheme was constructed in the 8th century to justify the status of powerful political groupings by projecting the origins of their rule into the remote past. All of the Irish kingdoms had their own kings but were nominally subject to the high king. The high king was drawn from the ranks of the provincial kings and ruled also the royal kingdom of Meath , with a ceremonial capital at the Hill of Tara . The concept did not become

The full field, including the end zones, covers about 1.32 acres (0.53 ha). For residents of other countries, the acre might be envisioned as rather more than half of a 1.76 acres (0.71 ha) football pitch . The word acre

Following the 12th century Anglo-Norman invasion , England claimed sovereignty. However, English rule did not extend over
10101-466: The traditional unit of area was Morgen . Like the acre, the morgen was a unit of ploughland, representing a strip that could be ploughed by one man and an ox or horse in a morning. There were many variants of the morgen , differing between the different German territories, ranging from 1 ⁄ 2 to 2 + 1 ⁄ 2 acres (2,000 to 10,100 m ). It was also used in Old Prussia , in
10212-540: The traditional unit of area was the arpent carré , a measure based on the Roman system of land measurement. The acre was used only in Normandy (and neighbouring places outside its traditional borders), but its value varied greatly across Normandy, ranging from 3,632 to 9,725 square metres, with 8,172 square metres being the most frequent value. But inside the same pays of Normandy, for instance in pays de Caux ,
10323-531: The treaty, led by Éamon de Valera . The civil war officially ended in May 1923 when de Valera issued a cease-fire order.

Physician-general William Petty estimated that 504,000 Catholic Irish and 112,000 Protestant settlers died, and 100,000 people were transported, as a result of the war. If a prewar population of 1.5 million is assumed, this would mean that the population was reduced by almost half. The religious struggles of

The prevalence amongst modern Irish men of this mutation is a remarkable 84%, the highest in the world, and closely matched in other populations along the Atlantic fringes down to Spain. A similar genetic replacement happened with lineages in mitochondrial DNA. This conclusion is supported by recent research carried out by
