World War IWorld War I or the First World War, often abbreviated as WWI or WW1, known contemporaneously as the Great War, was a major global conflict lasting from 1914 to 1918. It was fought between two coalitions, the Allies and the Central Powers. Fighting took place throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. The first decade of the 20th century saw increasing diplomatic tension between the European great powers.
Race to the SeaThe Race to the Sea (Course à la mer; Wettlauf zum Meer, Race naar de Zee) took place from about 1914 during the First World War, after the Battle of the Frontiers () and the German advance into France. The invasion had been stopped at the First Battle of the Marne (5–12 September) and was followed by the First Battle of the Aisne (13–28 September), a Franco-British counter-offensive. The term describes reciprocal attempts by the Franco-British and German armies to envelop the northern flank of the opposing army through the provinces of Picardy, Artois and Flanders, rather than an attempt to advance northwards to the sea.
Battle of the FrontiersThe Battle of the Frontiers (Bataille des Frontières, Grenzschlachten, Slag der Grenzen) comprised battles fought along the eastern frontier of France and in southern Belgium, shortly after the outbreak of the First World War. The battles resolved the military strategies of the French Chief of Staff General Joseph Joffre with Plan XVII and an offensive adaptation of the German Aufmarsch II deployment plan by Helmuth von Moltke the Younger. The German concentration on the right (northern) flank, was to wheel through Belgium and attack the French in the rear.
Schlieffen PlanThe Schlieffen Plan (Schlieffen-Plan, ʃliːfən plaːn) is a name given after the First World War to German war plans, due to the influence of Field Marshal Alfred von Schlieffen and his thinking on an invasion of France and Belgium, which began on 4 August 1914. Schlieffen was Chief of the General Staff of the German Army from 1891 to 1906. In 1905 and 1906, Schlieffen devised an army deployment plan for a decisive (war-winning) offensive against the French Third Republic.
Trench warfareTrench warfare is the type of land warfare using occupied lines largely comprising military trenches, in which troops are well-protected from the enemy's small arms fire and are substantially sheltered from artillery. It became archetypically associated with World War I (1914–1918), when the Race to the Sea rapidly expanded trench use on the Western Front starting in September 1914. Trench warfare proliferated when a revolution in firepower was not matched by similar advances in mobility, resulting in a grueling form of warfare in which the defender held the advantage.
Battle of MonsThe Battle of Mons was the first major action of the British Expeditionary Force (BEF) in the First World War. It was a subsidiary action of the Battle of the Frontiers, in which the Allies clashed with Germany on the French borders. At Mons, the British Army attempted to hold the line of the Mons–Condé Canal against the advancing German 1st Army. Although the British fought well and inflicted disproportionate casualties on the numerically superior Germans, they were eventually forced to retreat due both to the greater strength of the Germans and the sudden retreat of the French Fifth Army, which exposed the British right flank.
Albert I of BelgiumAlbert I (8 April 1875 – 17 February 1934) was King of the Belgians from 23 December 1909 until his death in 1934. Albert was born in Brussels as the fifth child and second son of Prince Philippe, Count of Flanders, and Princess Marie of Hohenzollern-Sigmaringen, Albert succeeded his uncle Leopold II to the Belgian throne in 1909. He married Elisabeth of Bavaria, with whom he had three children. Albert ruled during an eventful period in the history of Belgium, which included the period of World War I (1914–1918), when most of Belgium was occupied by German forces.
Allies of World War IThe Allies, or the Entente Powers, were an international military coalition of countries led by France, the United Kingdom, Russia, the United States, Italy, and Japan against the Central Powers of Germany, Austria-Hungary, the Ottoman Empire, and Bulgaria in World War I (1914–1918). By the end of the first decade of the 20th century, the major European powers were divided between the Triple Entente and the Triple Alliance. The Triple Entente was made up of the United Kingdom, France, and Russia.
First Battle of the AisneThe First Battle of the Aisne (1re Bataille de l'Aisne) was the Allied follow-up offensive against the right wing of the German First Army (led by Alexander von Kluck) and the Second Army (led by Karl von Bülow) as they retreated after the First Battle of the Marne earlier in September 1914. The Advance to the Aisne (6 September – 1 October) consisted of the Battle of the Marne (7–10 September) and the Battle of the Aisne (12–15 September).
Alexander von KluckAlexander Heinrich Rudolph von Kluck (20 May 1846 – 19 October 1934) was a German general during World War I. Kluck was born in Münster, Westphalia on 20 May 1846. He was the son of architect Karl von Kluck and his wife Elisabeth, née Tiedemann. He was a pupil at a school called Paulinum in his hometown of Münster. In 1874 he married Fanny von Donop (1850–1938); they had three sons and one daughter.
