The Pas-de-Calais ( French: [pɑ d(ə) kalɛ] , " strait of Calais "; Picard : Pas-Calés ; Dutch : Nauw van Calais ) is a department in north-eastern France named after the French designation of the Strait of Dover , which it borders. It has the most communes of all the departments of France, with 890 , and is the 8th most populous. It had a population of 1,465,278 in 2019. The Calais Passage connects to the Port of Calais on the English Channel . The Pas-de-Calais borders the departments of Nord and Somme and is connected to the English county of Kent via the Channel Tunnel .
121-777: Inhabited since prehistoric times, the Pas-de-Calais region was populated in turn by the Celtic Belgae , the Romans , the Germanic Franks and the Alemanni . During the fourth and fifth centuries, the Roman practice of co-opting Germanic tribes to provide military and defence services along the route from Boulogne-sur-Mer to Cologne created a Germanic - Romance linguistic border in the region that persisted until
242-523: A Bosnian Serb named Gavrilo Princip assassinated Archduke Franz Ferdinand , heir to the Austro-Hungarian throne. Austria-Hungary held Serbia responsible, and declared war on 28 July. After Russia mobilised in Serbia's defence, Germany declared war on Russia and France , who had an alliance . The United Kingdom entered after Germany invaded Belgium , whose neutrality it guaranteed, and
363-645: A blue-water navy was vital for global power projection; Tirpitz had his books translated into German, while Wilhelm made them required reading for his advisors and senior military personnel. However, it was also an emotional decision, driven by Wilhelm's simultaneous admiration for the Royal Navy and desire to surpass it. Bismarck thought that the British would not interfere in Europe, as long as its maritime supremacy remained secure, but his dismissal in 1890 led to
484-592: A grenade at the Archduke's car and injured two of his aides. The other assassins were also unsuccessful. An hour later, as Ferdinand was returning from visiting the injured officers in hospital, his car took a wrong turn into a street where Gavrilo Princip was standing. He fired two pistol shots, fatally wounding Ferdinand and his wife Sophie . According to historian Zbyněk Zeman , in Vienna "the event almost failed to make any impression whatsoever. On 28 and 29 June,
605-540: A guerrilla warfare campaign and only surrendered two weeks after the armistice took effect in Europe. Before the war, Germany had attempted to use Indian nationalism and pan-Islamism to its advantage, a policy continued post-1914 by instigating uprisings in India , while the Niedermayer–Hentig Expedition urged Afghanistan to join the war on the side of Central Powers. However, contrary to British fears of
726-562: A Proto-Celtic ethnic name *Bolgoi could be interpreted as "the people who swell (particularly with anger/battle fury)". In Caesar's usage, Belgium is a geographical subregion comprising the Bellovaci , Ambiani , Atrebates , and Veromandui . These four communities are widely thought to have been the original Belgae in Gaul. Julius Caesar describes Gaul at the time of his conquests (58–51 BC) as divided into three parts, inhabited by
847-627: A branch of the Belgae settled in Ireland around the 5th century BC , later becoming the historical Iverni (Érainn) and their offshoots. He believes the memory of Belgae settlers was preserved in medieval Irish legend as the Fir Bolg . O'Rahilly's theory has been challenged by historians and archaeologists, and is no longer accepted. Fintan O'Toole suggested the Keshcarrigan Bowl
968-408: A change in policy and an Anglo-German naval arms race began. Despite the vast sums spent by Tirpitz, the launch of HMS Dreadnought in 1906 gave the British a technological advantage. Ultimately, the race diverted huge resources into creating a German navy large enough to antagonise Britain, but not defeat it; in 1911, Chancellor Theobald von Bethmann Hollweg acknowledged defeat, leading to
1089-613: A direct threat. The 1908–1909 Bosnian Crisis began when Austria annexed the former Ottoman territory of Bosnia and Herzegovina , which it had occupied since 1878. Timed to coincide with the Bulgarian Declaration of Independence from the Ottoman Empire, this unilateral action was denounced by the European powers, but accepted as there was no consensus on how to resolve the situation. Some historians see this as
1210-471: A gap between the German armies as they closed on Paris. The French army, reinforced by the British expeditionary corps, seized this opportunity to counter-attack and pushed the German army 40 to 80 km back. Both armies were then so exhausted that no decisive move could be implemented, so they settled in trenches, with the vain hope of breaking through as soon as they could build local superiority. In 1911,
1331-725: A group of tribes within the Belgic alliance as the "Germani", distinguishing them from their neighbours. The most important of these tribes in relation to Caesar's campaigns were the Eburones . The other way he used the term was to refer to those related tribes east of the Rhine, who were not Celtic. So the Germani among the Belgae are called, based on Caesar's account, the Germani cisrhenani , to distinguish them from other Germani living east of

#17327662628941452-592: A large confederation of tribes living in northern Gaul , between the English Channel , the west bank of the Rhine , and the northern bank of the river Seine , from at least the third century BC. They were discussed in depth by Julius Caesar in his account of his wars in Gaul. Some peoples in southern Britain were also called Belgae and had apparently moved from the continent. T. F. O'Rahilly believed that some had moved further west and he equated them with
1573-549: A majority of the votes cast: 52.06%. There are currently two public universities in the department. Although it is one of the most populous departments of France, Pas-de-Calais did not contain a university until 1991 when the French government created two universities: ULCO (Université du Littoral Côte d'Opale) on the western part of the department, and Université d'Artois on the eastern part. Belgae The Belgae ( / ˈ b ɛ l dʒ iː , ˈ b ɛ l ɡ aɪ / ) were

German economic and industrial strength continued to expand rapidly post-1871. Backed by Wilhelm II, Admiral Alfred von Tirpitz sought to use this growth to build an Imperial German Navy , that could compete with the British Royal Navy . This policy was based on the work of US naval author Alfred Thayer Mahan , who argued that possession of
1815-834: A revolt in India, the outbreak of the war saw a reduction in nationalist activity. Leaders from the Indian National Congress and other groups believed support for the British war effort would hasten Indian Home Rule , a promise allegedly made explicit in 1917 by Edwin Montagu , the Secretary of State for India . In 1914, the British Indian Army was larger than the British Army itself, and between 1914 and 1918 an estimated 1.3 million Indian soldiers and labourers served in Europe, Africa, and
1936-553: A shield, made his way to the front line, and quickly organised his forces. The two Roman legions guarding the baggage train at the rear finally arrived and helped to turn the tide of the battle. Caesar says the Nervii were almost annihilated in the battle, and is effusive in his tribute to their bravery, calling them "heroes" (for more details see Battle of the Sabis ). The Atuatuci, who were marching to their aid, turned back on hearing of
2057-516: A significant escalation, ending any chance of Austria cooperating with Russia in the Balkans, while also damaging diplomatic relations between Serbia and Italy. Tensions increased after the 1911–1912 Italo-Turkish War demonstrated Ottoman weakness and led to the formation of the Balkan League , an alliance of Serbia, Bulgaria, Montenegro , and Greece . The League quickly overran most of
2178-525: A situation opposing Celtic and Germanic in Belgium, in a territory slightly more to the south than the early medieval Romance -Germanic language border", but van Durme accepts that Germanic did not block "Celticisation coming from the south" so "both phenomena were simultaneous and interfering". The medieval Gesta Treverorum compiled by monks of Trier claims that the Belgae were descendants of Trebeta , an otherwise unattested legendary founder of Trier,
2299-690: A tribe called the Tungri living where the Germani cisrhenani had lived, and he also stated that they had once been called the Germani (although Caesar had claimed to have wiped out the name of the main tribe, the Eburones). Other tribes that may have been included among the Belgae in some contexts were the Leuci , Treveri and Mediomatrici . Posidonius includes the Armoricani , as well. Caesar conquered
2420-478: A war on two fronts; the Schlieffen Plan envisaged using 80% of the army to defeat France, then switching to Russia. Since this required them to move quickly, mobilization orders were issued that afternoon. Once the German ultimatum to Russia expired on the morning of 1 August, the two countries were at war. At a meeting on 29 July, the British cabinet had narrowly decided its obligations to Belgium under
2541-402: A weak Ottoman government, rather than an ambitious Slav power like Bulgaria . Russia had ambitions in northeastern Anatolia while its clients had overlapping claims in the Balkans. These competing interests divided Russian policy-makers and added to regional instability. Austrian statesmen viewed the Balkans as essential for the continued existence of their Empire and saw Serbian expansion as

The diseases that emerged in the trenches were a major killer on both sides. The living conditions led to disease and infection, such as trench foot , lice , typhus , trench fever , and the ' Spanish flu '. At the start of the war, German cruisers were scattered across

World War I World War I or the First World War (28 July 1914 – 11 November 1918), also known as the Great War , was a global conflict between two coalitions: the Allies (or Entente) and the Central Powers . Fighting took place mainly in Europe and
2904-508: Is known, however, that from 1908 to 1913, military spending by the six major European powers increased by over 50% in real terms. The years before 1914 were marked by a series of crises in the Balkans, as other powers sought to benefit from the Ottoman decline. While Pan-Slavic and Orthodox Russia considered itself the protector of Serbia and other Slav states, they preferred the strategically vital Bosporus straits to be controlled by

The centre and south of the department are more rural, but still quite heavily populated, with many villages and small towns. Although the department saw some of the heaviest fighting of World War I , its population rebounded quickly after both world wars. However, many of
3146-574: The Schutzkorps was established, and carried out the persecution of Serbs. The assassination initiated the July Crisis, a month of diplomatic manoeuvring between Austria-Hungary, Germany, Russia, France and Britain. Believing that Serbian intelligence helped organise Franz Ferdinand's murder, Austrian officials wanted to use the opportunity to end their interference in Bosnia and saw war as
3267-641: The World War . In August 1914, the magazine The Independent wrote "This is the Great War. It names itself". In October 1914, the Canadian magazine Maclean's similarly wrote, "Some wars name themselves. This is the Great War." Contemporary Europeans also referred to it as " the war to end war " and it was also described as "the war to end all wars" due to their perception of its unparalleled scale, devastation, and loss of life. The first recorded use of

Each of these three parts, he says, differed in terms of customs, laws and language. He noted that the Belgae, were "the bravest, because they are furthest from the civilization and refinement of [our] Province, and merchants least frequently resort to them, and import those things which tend to effeminate
3509-719: The Atrebates , Caesar's former ally, fled to Britain after participating in Vercingetorix 's rebellion and either joined or established a British branch of his tribe. Based on the development of imagery on coins, by the time of the Roman conquest , some of the tribes of south-eastern Britain likely were ruled by a Belgic nobility and were culturally influenced by them. The later civitas (administrative division) of Roman Britain had towns including Portus Adurni ( Portchester ) and Clausentum ( Southampton ). The civitas capital

Thus,

The precise extent of their conquests is unknown. After the Roman conquest of Great Britain, the civitas of the Belgae was bordered to the north by the British Atrebates , who were also a Belgic tribe, and to the east by the Regni , who were probably linked to
4114-504: The Fir Bolg in Ireland . The Roman province of Gallia Belgica was named after the continental Belgae. The term continued to be used in the region until the present day and is reflected in the name of the modern country of Belgium . The consensus among linguists is that the ethnic name Belgae probably comes from the Proto-Celtic root *belg- or *bolg- meaning "to swell (particularly with anger/battle fury/etc.)", cognate with

It has been remarked that Germanic speakers might have been no closer than the river Elbe in the time of Caesar. However, studies of place names, such as those of Maurits Gysseling , have been argued to show evidence of the pre-Roman presence of early Germanic languages throughout
4356-475: The Germani cisrhenani , and this is indeed also true of the tribes immediately over the Rhine at this time, such as the Tencteri and Usipetes . Surviving inscriptions also indicate that Gaulish was spoken in at least part of Belgic territory. The Romans were not precise in their ethnography of northern barbarians : by "Germanic", Caesar may simply have meant "originating east of the Rhine" (the homeland of

The movement of large numbers of people
4598-721: The Rüstungswende or 'armaments turning point', when he switched expenditure from the navy to the army. This decision was not driven by a reduction in political tensions but by German concern over Russia's quick recovery from its defeat in the Russo-Japanese War and subsequent 1905 Russian Revolution . Economic reforms led to a significant post-1908 expansion of railways and transportation infrastructure, particularly in its western border regions. Since Germany and Austria-Hungary relied on faster mobilisation to compensate for their numerical inferiority compared to Russia,
4719-492: The Spanish Netherlands . Some of the costliest battles of World War I were fought in the region. The Canadian National Vimy Memorial , eight kilometres from Arras , commemorates the Battle of Vimy Ridge assault during the Battle of Arras (1917) and is Canada 's most important memorial in Europe to its fallen soldiers. Pas-de-Calais was also the target of Operation Fortitude during World War II , which

Convoys slowed the flow of supplies since ships had to wait as convoys were assembled; the solution was an extensive program of building new freighters. Troopships were too fast for the submarines and did not travel the North Atlantic in convoys. The U-boats sunk more than 5,000 Allied ships, at

After the First Battle of the Marne in September 1914, Allied and German forces unsuccessfully tried to outflank each other, a series of manoeuvres later known as the " Race to the Sea ". By the end of 1914, the opposing forces confronted each other along an uninterrupted line of entrenched positions from the Channel to the Swiss border. Since the Germans were normally able to choose where to stand, they generally held

It was created from parts of the former provinces of Calaisis , formerly English, Boulonnais , Ponthieu and Artois , this last formerly part of
5445-588: The 1839 Treaty of London did not require it to oppose a German invasion with military force; however, Prime Minister Asquith and his senior Cabinet ministers were already committed to supporting France, the Royal Navy had been mobilised, and public opinion was strongly in favour of intervention. On 31 July, Britain sent notes to Germany and France, asking them to respect Belgian neutrality; France pledged to do so, but Germany did not reply. Aware of German plans to attack through Belgium, French Commander-in-Chief Joseph Joffre asked his government for permission to cross
5566-431: The 1879 Dual Alliance , which became the Triple Alliance when Italy joined in 1882. For Bismarck, the purpose of these agreements was to isolate France by ensuring the three Empires resolve any disputes between themselves. In 1887, Bismarck set up the Reinsurance Treaty , a secret agreement between Germany and Russia to remain neutral if either were attacked by France or Austria-Hungary. For Bismarck, peace with Russia

However, disputes between the victors sparked the 33-day Second Balkan War , when Bulgaria attacked Serbia and Greece on 16 June 1913; it was defeated, losing most of Macedonia to Serbia and Greece, and Southern Dobruja to Romania. The result was that even countries which benefited from
5808-436: The 4th through the 1st centuries BC. The Belgae of this period do not appear to have drunk beer. Caesar's book Commentarii de Bello Gallico begins: "All Gaul is divided into three parts, one of which the Belgae inhabit, the Aquitani another, those who in their own language are called Celts, in ours Gauls, the third. All these differ from each other in language, customs and laws." However, many modern scholars believe that
5929-409: The Austrians and Serbs clashed at the battles of the Cer and Kolubara ; over the next two weeks, Austrian attacks were repulsed with heavy losses. As a result, Austria had to keep sizeable forces on the Serbian front, weakening their efforts against Russia. Serbia's victory against Austria-Hungary in the 1914 invasion has been called one of the major upset victories of the twentieth century. In 1915,
6050-593: The Austrians briefly occupied the Serbian capital, Belgrade . A Serbian counter-attack in the Battle of Kolubara succeeded in driving them from the country by the end of 1914. For the first 10 months of 1915, Austria-Hungary used most of its military reserves to fight Italy. German and Austro-Hungarian diplomats scored a coup by persuading Bulgaria to join the attack on Serbia. The Austro-Hungarian provinces of Slovenia , Croatia and Bosnia provided troops for Austria-Hungary. Montenegro allied itself with Serbia. Bulgaria declared war on Serbia on 14 October 1915 and joined in
6171-493: The Balkan Wars, such as Serbia and Greece, felt cheated of their "rightful gains", while for Austria it demonstrated the apparent indifference with which other powers viewed their concerns, including Germany. This complex mix of resentment, nationalism and insecurity helps explain why the pre-1914 Balkans became known as the " powder keg of Europe ". On 28 June 1914, Archduke Franz Ferdinand of Austria , heir presumptive to Emperor Franz Joseph I of Austria , visited Sarajevo ,

#17327662628946292-447: The Belgae as well. The arrival and spread of Aylesford-Swarling pottery across the southeastern corner of Britain has been related to the Belgic invasion since Arthur Evans published his excavation of Aylesford in 1890, which was then thought to show "the demonstrable reality of a Belgic invasion", according to Sir Barry Cunliffe , although more recent studies tend to downplay the role of migration in favour of increasing trade links;
6413-431: The Belgae decided to disband their combined force and return to their own lands. Caesar's informants advised him that whichever tribe Caesar attacked first, the others would come to their defence. They broke camp shortly before midnight. At daybreak, satisfied the retreat was not a trap, Caesar sent cavalry to harass the rear guard, followed by three legions. Many of the Belgae were killed in battle. Caesar next marched into
6534-405: The Belgae were a Celtic-speaking group. On the other hand, at least part of the Belgae may also have had significant cultural and historical connections to peoples east of the Rhine, including Germanic peoples , judging from archaeological, placename and textual evidence. It has also been argued based on placename studies that the older language of the area, though apparently Indo-European ,

He writes that the Belgae were conspiring and arming themselves in response to his earlier conquests; to counter this threat, he raised two new legions and ordered his Gallic allies, the Aedui , to invade the territory of the Bellovaci , the largest and fiercest of the Belgae tribes. Wary of the numbers and bravery of the Belgae, Caesar initially avoided a pitched battle, resorting mainly to cavalry skirmishes to probe their strengths and weaknesses. Once he
6776-421: The Belgae. ) It seems that, whatever their ancestry, at least some of the Belgic tribes spoke a variety of Gaulish as their main language by Caesar's time, and all of them used such languages in at least some contexts. Luc van Durme summarizes competing evidence of Celtic and Germanic influence at the time of Caesar by saying that "one has to accept the rather remarkable conclusion that Caesar must have witnessed
6897-429: The Belgic area north of the Ardennes , where the Germani cisrhenani lived. The sound changes described by " Grimm's law " appear to have affected names with older forms, apparently already in the second century BC. Strong evidence for old Celtic placenames, though, is found in the Ardennes and to the south of them. According to Strabo , the country of the Belgae extended along the coast where 15 tribes were living from

After Vienna refused to withdraw its cruiser SMS Kaiserin Elisabeth from Tsingtao, Japan declared war on Austria-Hungary, and the ship was sunk in November 1914. Within a few months, Allied forces had seized all German territories in the Pacific, leaving only isolated commerce raiders and a few holdouts in New Guinea. Some of the first clashes of

The nature of submarine warfare meant that attacks often came without warning, giving the crews of the merchant ships little hope of survival. The United States launched a protest, and Germany changed its rules of engagement. After the sinking of the passenger ship RMS Lusitania in 1915, Germany promised not to target passenger liners, while Britain armed its merchant ships, placing them beyond

He also considered Dutch neutrality essential for German trade and cancelled the incursion into the Netherlands, which meant any delays in Belgium threatened the viability of the plan. Historian Richard Holmes argues that these changes meant the right wing was not strong enough to achieve decisive success. The initial German advance in

The plan's creator, Alfred von Schlieffen , head of the German General Staff from 1891 to 1906, estimated that this would take six weeks, after which the German army would transfer to the East and defeat the Russians. The plan was substantially modified by his successor, Helmuth von Moltke

The Battle of the Somme was an Anglo-French offensive from July to November 1916. The opening day on 1 July 1916 was the bloodiest single day in the history of the British Army , which suffered 57,500 casualties, including 19,200 dead. As

The suffering engendered by the war, as well as the failure of the British government to grant self-government to India afterward, bred disillusionment, resulting in the campaign for full independence led by Mahatma Gandhi . Pre-war military tactics that had emphasised open warfare and individual riflemen proved obsolete when confronted with conditions prevailing in 1914. Technological advances allowed

After their final subjugation, Caesar combined the three parts of Gaul, the territory of the Belgae, Celtae and Aquitani, into a single unwieldy province ( Gallia Comata , "long-haired Gaul") that was reorganized by the emperor Augustus into its traditional cultural divisions. The province of Gallia Belgica
7986-545: The Ottomans joined the Central Powers in November. Germany's strategy in 1914 was to quickly defeat France, then to transfer its forces to the east, but its advance was halted in September , and by the end of the year the Western Front consisted of a continuous line of trenches stretching from the English Channel to Switzerland. The Eastern Front was more dynamic, but neither side gained a decisive advantage, despite costly offensives. Italy , Bulgaria , Romania , Greece and others joined in from 1915 onward. In April 1917,

The Serbian capture of ports on the Adriatic resulted in partial Austrian mobilisation, starting on 21 November 1912, including units along the Russian border in Galicia . The Russian government decided not to mobilise in response, unprepared to precipitate a war. The Great Powers sought to re-assert control through

By the end of 1914, German troops held strong defensive positions inside France, controlled the bulk of France's domestic coalfields, and inflicted 230,000 more casualties than it lost itself. However, communications problems and questionable command decisions cost Germany
8712-650: The Serbian retreat toward the Adriatic coast in the Battle of Mojkovac on 6–7 January 1916, but ultimately the Austrians also conquered Montenegro. The surviving Serbian soldiers were evacuated to Greece. After the conquest, Serbia was divided between Austro-Hungary and Bulgaria. In late 1915, a Franco-British force landed at Salonica in Greece to offer assistance and to pressure its government to declare war against
8833-651: The West was very successful. By the end of August, the Allied left, which included the British Expeditionary Force (BEF), was in full retreat , and the French offensive in Alsace-Lorraine was a disastrous failure, with casualties exceeding 260,000. German planning provided broad strategic instructions while allowing army commanders considerable freedom in carrying them out at the front, but von Kluck used this freedom to disobey orders, opening
8954-485: The Younger . Under Schlieffen, 85% of German forces in the west were assigned to the right wing, with the remainder holding along the frontier. By keeping his left-wing deliberately weak, he hoped to lure the French into an offensive into the "lost provinces" of Alsace-Lorraine , which was the strategy envisaged by their Plan XVII . However, Moltke grew concerned that the French might push too hard on his left flank and as
9075-501: The aggressor, German Chancellor Bethmann Hollweg delayed the commencement of war preparations until 31 July. That afternoon, the Russian government were handed a note requiring them to "cease all war measures against Germany and Austria-Hungary" within 12 hours. A further German demand for neutrality was refused by the French who ordered general mobilization but delayed declaring war. The German General Staff had long assumed they faced
9196-474: The attack by the Austro-Hungarian army under Mackensen's army of 250,000 that was already underway. Serbia was conquered in a little more than a month, as the Central Powers, now including Bulgaria, sent in 600,000 troops in total. The Serbian army, fighting on two fronts and facing certain defeat, retreated into northern Albania . The Serbs suffered defeat in the Battle of Kosovo . Montenegro covered
9317-543: The best way of achieving this. However, the Foreign Ministry had no solid proof of Serbian involvement. On 23 July, Austria delivered an ultimatum to Serbia, listing ten demands made intentionally unacceptable to provide an excuse for starting hostilities. Serbia ordered general mobilization on 25 July, but accepted all the terms, except for those empowering Austrian representatives to suppress "subversive elements" inside Serbia, and take part in
9438-483: The border and pre-empt such a move. To avoid violating Belgian neutrality, he was told any advance could come only after a German invasion. Instead, the French cabinet ordered its Army to withdraw 10 km behind the German frontier, to avoid provoking war. On 2 August, Germany occupied Luxembourg and exchanged fire with French units when German patrols entered French territory; on 3 August, they declared war on France and demanded free passage across Belgium, which
9559-600: The campaign saw the first use of anti-aircraft warfare after an Austrian plane was shot down with ground-to-air fire, as well as the first medical evacuation by the Serbian army. Upon mobilisation, in accordance with the Schlieffen Plan , 80% of the German Army was located on the Western Front, with the remainder acting as a screening force in the East. Rather than a direct attack across their shared frontier,
9680-649: The capital of the recently annexed Bosnia and Herzegovina . Cvjetko Popović , Gavrilo Princip , Nedeljko Čabrinović , Trifko Grabež , Vaso Čubrilović ( Bosnian Serbs ) and Muhamed Mehmedbašić (from the Bosniaks community), from the movement known as Young Bosnia , took up positions along the Archduke's motorcade route, to assassinate him. Supplied with arms by extremists within the Serbian Black Hand intelligence organisation, they hoped his death would free Bosnia from Austrian rule. Čabrinović threw
9801-466: The chance of a decisive outcome, while it had failed to achieve the primary objective of avoiding a long, two-front war. As was apparent to several German leaders, this amounted to a strategic defeat; shortly after the First Battle of the Marne , Crown Prince Wilhelm told an American reporter "We have lost the war. It will go on for a long time but lost it is already." On 30 August 1914, New Zealand occupied German Samoa (now Samoa ). On 11 September,
9922-520: The cost of 199 submarines. World War I also saw the first use of aircraft carriers in combat, with HMS Furious launching Sopwith Camels in a successful raid against the Zeppelin hangars at Tondern in July 1918, as well as blimps for antisubmarine patrol. Faced with Russia in the east, Austria-Hungary could spare only one-third of its army to attack Serbia. After suffering heavy losses,
10043-522: The creation of new independent states, including Poland , Finland , the Baltic states , Czechoslovakia , and Yugoslavia . The League of Nations was established to maintain world peace, but its failure to manage instability during the interwar period contributed to the outbreak of World War II in 1939. Before World War II , the events of 1914–1918 were generally known as the Great War or simply
10164-449: The creation of strong defensive systems largely impervious to massed infantry advances, such as barbed wire , machine guns and above all far more powerful artillery , which dominated the battlefield and made crossing open ground extremely difficult. Both sides struggled to develop tactics for breaching entrenched positions without heavy casualties. In time, technology enabled the production of new offensive weapons, such as gas warfare and
10285-965: The crowds listened to music and drank wine, as if nothing had happened." Nevertheless, the impact of the murder of the heir to the throne was significant, and has been described by historian Christopher Clark as a "9/11 effect, a terrorist event charged with historic meaning, transforming the political chemistry in Vienna". Austro-Hungarian authorities encouraged subsequent anti-Serb riots in Sarajevo . Violent actions against ethnic Serbs were also organised outside Sarajevo, in other cities in Austro-Hungarian-controlled Bosnia and Herzegovina, Croatia and Slovenia. Austro-Hungarian authorities in Bosnia and Herzegovina imprisoned approximately 5,500 prominent Serbs, 700 to 2,200 of whom died in prison. A further 460 Serbs were sentenced to death. A predominantly Bosniak special militia known as
10406-515: The defeat and retreated to one stronghold, were put under siege, and soon surrendered and handed over their arms. However, the surrender was a ploy, and the Atuatuci, armed with weapons they had hidden, tried to break out during the night. The Romans had the advantage of position and killed 4,000. The rest, about 53,000, were sold into slavery. In 53 BC, the Eburones, led by Ambiorix , along with
10527-423: The eighth century. Saxon colonization into the region from the fifth to the eighth centuries likely extended the linguistic border somewhat south and west so that by the ninth century most inhabitants north of the line between Béthune and Berck spoke a dialect of Middle Dutch , while the inhabitants to the south spoke Picard , a variety of Romance dialects . This linguistic border is still evident today in
10648-695: The expansion of the French colonial empire . In 1873, Bismarck negotiated the League of the Three Emperors , which included Austria-Hungary , Russia and Germany. After the 1877–1878 Russo-Turkish War , the League was dissolved due to Austrian concerns over the expansion of Russian influence in the Balkans , an area they considered to be of vital strategic interest. Germany and Austria-Hungary then formed
10769-400: The first time on the Western Front. Several types of gas soon became widely used by both sides and though it never proved a decisive, battle-winning weapon, it became one of the most feared and best-remembered horrors of the war. In February 1916, the Germans attacked French defensive positions at the Battle of Verdun , lasting until December 1916. Casualties were greater for the French, but
10890-555: The forests and attacked the approaching Roman column at the river Sabis (previously thought to be the Sambre , but recently the Selle is thought to be more probable). Their attack was quick and unexpected. The element of surprise briefly left the Romans exposed. Some of the Romans did not have time to take the covers off their shields or to even put on their helmets. However, Caesar grabbed
11011-595: The front. Serbian and French troops finally made a breakthrough in September 1918 in the Vardar offensive , after most German and Austro-Hungarian troops had been withdrawn. The Bulgarians were defeated at the Battle of Dobro Pole , and by 25 September British and French troops had crossed the border into Bulgaria proper as the Bulgarian army collapsed. Bulgaria capitulated four days later, on 29 September 1918. The German high command responded by despatching troops to hold
11132-402: The funerary practice of communities to the north and south. Around this same time, a characteristic form of enclosed sanctuary began to be built, and from the late 2nd through the mid 1st centuries BC, fortifications with a high earthen rampart and a wide, flat-bottomed ditch are concentrated there. The coinage of the Belgae in Gaul shows commonalities in design and distribution patterns from
11253-542: The globe, some of which were subsequently used to attack Allied merchant shipping . These were systematically hunted down by the Royal Navy, though not before causing considerable damage. One of the most successful was the SMS ; Emden , part of the German East Asia Squadron stationed at Qingdao , which seized or sank 15 merchantmen, a Russian cruiser and a French destroyer. Most of the squadron
11374-549: The high ground, while their trenches tended to be better built; those constructed by the French and English were initially considered "temporary", only needed until an offensive would destroy the German defences. Both sides tried to break the stalemate using scientific and technological advances. On 22 April 1915, at the Second Battle of Ypres , the Germans (violating the Hague Convention ) used chlorine gas for
11495-470: The investigation and trial of Serbians linked to the assassination. Claiming this amounted to rejection, Austria broke off diplomatic relations and ordered partial mobilisation the next day; on 28 July, they declared war on Serbia and began shelling Belgrade . Russia ordered general mobilization in support of Serbia on 30 July. Anxious to ensure backing from the SPD political opposition by presenting Russia as
11616-542: The mind; and they are the nearest to the Germans, who dwell beyond the Rhine, with whom they are continually waging war". Ancient sources such as Caesar are not always clear about the things used to define ethnicity today. While Caesar or his sources described the Belgae as distinctly different from the Gauls, Strabo stated that the differences between the Celts (Gauls) and Belgae in countenance, language, politics and way of life
11737-541: The mining towns have seen dramatic decreases in population, some up to half of their population. Population development since 1801: The president of the Departmental Council is Jean-Claude Leroy, elected in 2017. In the second round of the French presidential elections of 2017 Pas-de-Calais was one of only two departments in which the candidate of the Front National , Marine Le Pen , received
11858-465: The ocean, even to neutral ships. Since there was limited response to this tactic, Germany expected a similar response to its unrestricted submarine warfare. The Battle of Jutland in May/June 1916 was the only full-scale clash of battleships during the war, and one of the largest in history. The clash was indecisive, though the Germans inflicted more damage than they received; thereafter the bulk of
11979-473: The other [he assigned] to the Belgae ( Gallia Belgica )." Apart from the Germani, the report of Caesar seems to indicate that more of the Belgae had some Germanic ethnicity, but this is not necessarily what defines a tribe as Belgic. Edith Wightman proposed that Caesar can be read as treating only the southwestern Belgic tribes, the Suessiones, Viromandui and Ambiani and perhaps some of their neighbours, as
12100-801: The protection of the " cruiser rules ", which demanded warning and movement of crews to "a place of safety" (a standard that lifeboats did not meet). Finally, in early 1917, Germany adopted a policy of unrestricted submarine warfare , realising the Americans would eventually enter the war. Germany sought to strangle Allied sea lanes before the United States could transport a large army overseas, but, after initial successes, eventually failed to do so. The U-boat threat lessened in 1917, when merchant ships began travelling in convoys , escorted by destroyers . This tactic made it difficult for U-boats to find targets, which significantly lessened losses; after
12221-648: The question remains unclear. A large number of coins of the Ambiani dating to the mid-second century BC have been found in southern Britain and the remains of a possible Belgic fort have been unearthed in Kent. Within memory of Caesar's time, a king of the Suessiones (also referred to as Suaeuconi) called Diviciacus was not only the most powerful king of Belgic Gaul, but also ruled territory in Britain. Commius of
12342-469: The term First World War was in September 1914 by German biologist and philosopher Ernst Haeckel who stated, "There is no doubt that the course and character of the feared 'European War' ... will become the first world war in the full sense of the word." For much of the 19th century, the major European powers maintained a tenuous balance of power , known as the Concert of Europe . After 1848, this
12463-684: The territory of the Suessiones and besieged the town of Noviodunum ( Soissons ). Seeing the Romans' siege engines , the Suessiones surrendered, whereupon Caesar turned his attention to the Bellovaci, who had retreated into the fortress of Bratuspantium (between modern Amiens and Beauvais ). They quickly surrendered, as did the Ambiani. The Nervii , along with the Atrebates and Viromandui, decided to fight (the Atuatuci had also agreed to join them, but had not yet arrived). They concealed themselves in
12584-414: The third through the first centuries BC within this subregion, inhabited in the time of Caesar by Bellovaci, Ambiani, Atrebates, and Veromandui. From 250 BC onward, the disposal of the dead was primarily through cremation, with some inhumation practiced. Ceramics and brooches are typical grave goods, while items of feasting appear in wealthier graves. The absence of weapons distinguishes these burials from
12705-691: The threat posed by the closing of this gap was more important than competing with the Royal Navy. After Germany expanded its standing army by 170,000 troops in 1913, France extended compulsory military service from two to three years; similar measures were taken by the Balkan powers and Italy, which led to increased expenditure by the Ottomans and Austria-Hungary. Absolute figures are difficult to calculate due to differences in categorising expenditure since they often omit civilian infrastructure projects like railways which had logistical importance and military use. It
12826-505: The true ethnic Belgae, as opposed to those in a political and military alliance with them. She reads Caesar as implying a "transition zone" of mixed ethnicity and ancestry for the Menapii , Nervii and Morini , all living in the northwest of the Belgic region, neighbours to the Germani cisrhenani in the northeast. (Caesar also mentions his allies the Remi being closest to the Celts amongst
12947-590: The war ended with the Armistice of 11 November 1918 . The Paris Peace Conference of 1919–1920 imposed settlements on the defeated powers, most notably the Treaty of Versailles , by which Germany lost significant territories, was disarmed, and was required to pay large war reparations to the Allies. The dissolution of the Russian, German, Austro-Hungarian, and Ottoman Empires redrew national boundaries and resulted in
13068-601: The war involved British, French, and German colonial forces in Africa. On 6–7 August, French and British troops invaded the German protectorates of Togoland and Kamerun . On 10 August, German forces in South-West Africa attacked South Africa; sporadic and fierce fighting continued for the rest of the war. The German colonial forces in German East Africa , led by Colonel Paul von Lettow-Vorbeck , fought
13189-418: The west , which despite initial successes left the German Army exhausted and demoralised. A successful Allied counter-offensive from August 1918 caused a collapse of the German front line. By early November, Bulgaria, the Ottoman Empire and Austria-Hungary had each signed armistices with the Allies, leaving Germany isolated. Facing a revolution at home , Kaiser Wilhelm II abdicated on 9 November, and
13310-432: Was a major factor in the deadly Spanish flu pandemic. The causes of World War I included the rise of Germany and decline of the Ottoman Empire , which disturbed the long-standing balance of power in Europe, as well as economic competition between nations triggered by industrialisation and imperialism . Growing tensions between the great powers and in the Balkans reached a breaking point on 28 June 1914, when
13431-554: Was a small one, unlike the difference between the Aquitanians and Celts. The fact that the Belgae were living in Gaul means that in one sense they were Gauls. This may be Caesar's meaning when he says "The Belgae have the same method of attacking a fortress as the rest of the Gauls". Inconsistently, Caesar in Bello Gallico , II.4 also contrasted them with Gauls: So Caesar used the word "Germani" in two ways. He described
13552-629: Was an Allied plan to deceive the Germans that the invasion of Europe at D-Day was to occur here, rather than in Normandy . Pas-de-Calais is in the current region of Hauts-de-France and is surrounded by the departments of Nord and Somme , the English Channel , and the North Sea . It shares a maritime border with the English county of Kent in the United Kingdom halfway through
13673-447: Was at Venta Belgarum ( Winchester ), which was built on top of an Iron Age oppidum (this was itself built on the site of two earlier abandoned hillforts ); Winchester remains Hampshire's county town to this day. In addition to Venta Belgarum, the ancient geographer Ptolemy lists Aquae Calidae ( Bath ) and Iscalis as poleis of the Belgae. In his theory of Ireland's prehistory, T. F. O'Rahilly suggested in 1946 that
13794-473: Was bounded on its east by the Rhine and extended all the way from the North Sea to Lake Constance ( Lacus Brigantinus ), including parts of what is now western Switzerland, with its capital at the city of the Remi (Reims). Under Diocletian , Belgica Prima (capital Augusta Trevirorum, Trier ) and Belgica Secunda (capital Reims ) formed part of the diocese of Gaul. The Belgae had made their way across
13915-403: Was challenged by Britain's withdrawal into so-called splendid isolation , the decline of the Ottoman Empire , New Imperialism , and the rise of Prussia under Otto von Bismarck . Victory in the 1870–1871 Franco-Prussian War allowed Bismarck to consolidate a German Empire . Post-1871, the primary aim of French policy was to avenge this defeat, but by the early 1890s, this had switched to
14036-500: Was later adopted as a collective name for the non-Celtic peoples beyond the Rhine, the other, better-known way that Caesar used the term. The cultural cohesion of Belgium as Caesar sketched it is suggested by the maintaining of these borders, more or less, in administrative divisions ( pagi ) mapped out later by the Romans and still evident in the parishes of the Carolingian era . Archaeology suggests cultural continuities from
14157-525: Was not Celtic (see Nordwestblock ) and that Celtic, though influential amongst the elite, might never have been the main language of the part of the Belgic area north of the Ardennes. For example, Maurits Gysseling suggested that prior to Celtic and Germanic influences the Belgae may have comprised a distinct Indo-European branch, termed Belgian . However, most of the Belgic tribal and personal names recorded are identifiably Gaulish , including those of
14278-654: Was refused. Early on the morning of 4 August, the Germans invaded, and Albert I of Belgium called for assistance under the Treaty of London . Britain sent Germany an ultimatum demanding they withdraw from Belgium; when this expired at midnight, without a response, the two empires were at war. Germany promised to support Austria-Hungary's invasion of Serbia, but interpretations of what this meant differed. Previously tested deployment plans had been replaced early in 1914, but those had never been tested in exercises. Austro-Hungarian leaders believed Germany would cover its northern flank against Russia. Beginning on 12 August,
14399-723: Was returning to Germany when it sank two British armoured cruisers at the Battle of Coronel in November 1914, before being virtually destroyed at the Battle of the Falkland Islands in December. The SMS Dresden escaped with a few auxiliaries, but after the Battle of Más a Tierra , these too were either destroyed or interned. Soon after the outbreak of hostilities, Britain began a naval blockade of Germany . This proved effective in cutting off vital supplies, though it violated accepted international law. Britain also mined international waters which closed off entire sections of
14520-464: Was satisfied his troops were a match for them, he made camp on a low hill protected by a marsh at the front and the river Aisne behind, near Bibrax (between modern Laon and Reims ) in the territory of the Remi. The Belgae attacked over the river, but were repulsed after a fierce battle. Realising they could not dislodge the Romans and aware of the approach of the Aedui into the lands of the Bellovaci,
14641-781: Was the foundation of German foreign policy but in 1890, he was forced to retire by Wilhelm II . The latter was persuaded not to renew the Reinsurance Treaty by his new Chancellor , Leo von Caprivi . This gave France an opening to agree the Franco-Russian Alliance in 1894, which was then followed by the 1904 Entente Cordiale with Britain. The Triple Entente was completed by the 1907 Anglo-Russian Convention . While not formal alliances, by settling long-standing colonial disputes in Asia and Africa, British support for France or Russia in any future conflict became
