Western Front (World War I) in the context of "Italian Front (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. Major areas of conflict included Europe and the Middle East, as well as parts of Africa and the Asia-Pacific. The war saw important developments in weaponry including tanks, aircraft, artillery, machine guns, and chemical weapons. One of the deadliest conflicts in history, it resulted in an estimated 30 million military casualties, and 8 million civilian deaths from war-related causes and genocide. The movement of large numbers of people was a major factor in the deadly Spanish flu pandemic.

The causes of World War I included the rise of the German Empire and decline of the Ottoman Empire, which disturbed the long-standing balance of power in Europe, the exacerbation of imperial rivalries, and an arms race between the great powers. Growing tensions in the Balkans reached a breaking point on 28 June 1914 when Gavrilo Princip, a Bosnian Serb, assassinated Franz Ferdinand, the heir to the Austro-Hungarian throne. Austria-Hungary blamed Serbia, 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 the war after Germany invaded Belgium, and the Ottoman Empire joined the Central Powers in November. Germany's strategy in 1914 was to quickly defeat France before transferring 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 near-continuous line of trenches 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 entered the war from 1915 onward.

Armoured warfare is the use of armoured fighting vehicles in modern warfare. It is a major component of modern methods of war. The premise of armoured warfare rests on the ability of troops to penetrate conventional defensive lines through use of manoeuvre by armoured units.

Much of the application of armoured warfare depends on the use of tanks and related vehicles used by other supporting arms such as infantry fighting vehicles, self-propelled artillery, and other combat vehicles, as well as mounted combat engineers and other support units. The doctrine of armoured warfare was developed to break the static nature of World War I trench warfare on the Western Front, and return to the 19th century school of thought that advocated manoeuvre and decisive battle outcomes in military strategy.

Alvin Cullum York (December 13, 1887 – September 2, 1964), also known by his rank as Sergeant York, was an American soldier who was one of the most decorated United States Army soldiers of World War I. He received the Medal of Honor for leading an attack on a German machine gun nest, gathering 35 machine guns, killing at least 25 enemy soldiers, and capturing 132 prisoners. York's Medal of Honor action occurred during the United States-led portion of the Meuse–Argonne offensive in France, which was intended to breach the Hindenburg line and force the Germans to surrender. He earned decorations from several Allied countries during the war, including France, Italy, and Montenegro.

York was born in rural Tennessee, in what is now the community of Pall Mall in Fentress County. His parents farmed, and his father also worked as a blacksmith. The 11 York children had minimal schooling because they helped provide for the family, including hunting, fishing, and working as laborers. After the death of his father, York assisted in caring for his younger siblings and found work as a blacksmith. Despite being a regular churchgoer, York also drank heavily and was prone to fistfights. After a 1914 conversion experience, he vowed to improve and became even more devoted to the Church of Christ in Christian Union. York was drafted during World War I; he initially claimed conscientious objector status on the grounds that his religious denomination forbade violence. Persuaded that his religion was not incompatible with military service, York joined the 82nd Division as an infantry private and went to France in 1918.

Sir Robert Eric Mortimer Wheeler CH CIE MC TD FRS FBA FSA (10 September 1890 – 22 July 1976) was a British archaeologist and officer in the British Army. Over the course of his career, he served as Director of both the National Museum of Wales and London Museum, Director-General of the Archaeological Survey of India, and the founder and Honorary Director of the Institute of Archaeology in London, in addition to writing twenty-four books on archaeological subjects.

Born in Glasgow to a middle-class family, Wheeler was raised largely in Yorkshire before moving to London in his teenage years. After studying classics at University College London (UCL), he began working professionally in archaeology, specialising in the Romano-British period. During World War I he volunteered for service in the Royal Artillery, being stationed on the Western Front, where he rose to the rank of major and was awarded the Military Cross. Returning to Britain, he obtained his doctorate from UCL before taking on a position at the National Museum of Wales, first as Keeper of Archaeology and then as Director, during which time he oversaw excavation at the Roman forts of Segontium, Y Gaer, and Isca Augusta with the aid of his first wife, Tessa Wheeler. Influenced by the archaeologist Augustus Pitt Rivers, Wheeler argued that excavation and the recording of stratigraphic context required an increasingly scientific and methodical approach, developing the "Wheeler method". In 1926, he was appointed Keeper of the London Museum; there, he oversaw a reorganisation of the collection, successfully lobbied for increased funding, and began lecturing at UCL.

Sir Winston Leonard Spencer Churchill (30 November 1874 – 24 January 1965) was a British statesman, military officer, and writer who was Prime Minister of the United Kingdom from 1940 to 1945 (during the Second World War) and again from 1951 to 1955. For some 62 of the years between 1900 and 1964, he was a Member of Parliament (MP) and represented a total of five constituencies over that time. Ideologically an adherent to economic liberalism and imperialism, he was for most of his career a member of the Conservative Party, which he led from 1940 to 1955. He was a member of the Liberal Party from 1904 to 1924.

Of mixed English and American parentage, Churchill was born in Oxfordshire into the wealthy, aristocratic Spencer family. He joined the British Army in 1895 and saw action in British India, the Mahdist War and the Second Boer War, gaining fame as a war correspondent and writing books about his campaigns. Elected a Conservative MP in 1900, he defected to the Liberals in 1904. In H. H. Asquith's Liberal government, Churchill was president of the Board of Trade and later Home Secretary, championing prison reform and workers' social security. As First Lord of the Admiralty before and during the First World War he oversaw the disastrous naval attack on the Dardanelles (a prelude to the Gallipoli campaign) and was demoted to Chancellor of the Duchy of Lancaster. He resigned in November 1915 and joined the Royal Scots Fusiliers on the Western Front for six months. In 1917, he returned to government under David Lloyd George and served successively as Minister of Munitions, Secretary of State for War, Secretary of State for Air, and Secretary of State for the Colonies, overseeing the Anglo-Irish Treaty and British foreign policy in the Middle East. After two years out of Parliament, he was Chancellor of the Exchequer in Stanley Baldwin's Conservative government, returning sterling in 1925 to the gold standard, depressing the UK economy.

Fritz Erich Georg Eduard von Manstein (born Fritz Erich Georg Eduard von Lewinski; 24 November 1887 – 9 June 1973) was a German military officer who served as a Generalfeldmarschall (Field Marshal) in the Heer (Army) of Nazi Germany during World War II. He was subsequently convicted of war crimes and sentenced to 18 years' imprisonment.

Born into an aristocratic Prussian family with a long history of military service, Manstein joined the army at a young age and saw service on both the Western and Eastern Front during the First World War (1914–18). He rose to the rank of captain by the end of the war and was active in the inter-war period helping Germany rebuild its armed forces. In September 1939, during the invasion of Poland at the beginning of the Second World War, he served as Chief of Staff to Gerd von Rundstedt's Army Group South. Adolf Hitler chose Manstein's strategy for the invasion of France of May 1940, a plan later refined by Franz Halder and other members of the OKH.

The Battle of Verdun (French: Bataille de Verdun [bataj də vɛʁdœ̃]; German: Schlacht um Verdun [ʃlaxt ʔʊm ˈvɛɐ̯dœ̃]) was fought from 21 February to 18 December 1916 on the Western Front in France. The battle was the longest of the First World War and took place on the hills north of Verdun. The German 5th Army attacked the defences of the Fortified Region of Verdun (RFV, Région Fortifiée de Verdun) and those of the French Second Army on the right (east) bank of the Meuse. Using the experience of the Second Battle of Champagne in 1915, the Germans planned to capture the Meuse Heights, an excellent defensive position, with good observation for artillery-fire on Verdun. The Germans hoped that the French would commit their strategic reserve to recapture the position and suffer catastrophic losses at little cost to the German infantry.

Poor weather delayed the beginning of the attack until 21 February but the Germans captured Fort Douaumont in the first three days. The advance then slowed for several days, despite inflicting many French casualties. By 6 March, 20+1⁄2 French divisions were in the RFV and a more extensive defence in depth had been organised. Philippe Pétain ordered there to be no retreat and that German attacks were to be counter-attacked, despite this exposing French infantry to the German artillery. By 29 March, French guns on the west bank had begun a constant bombardment of Germans on the east bank, causing many infantry casualties. The German offensive was extended to the west bank of the Meuse to gain observation and eliminate the French artillery firing over the river but the attacks failed to reach their objectives.

Douglas MacArthur (26 January 1880 – 5 April 1964) was an American general who served as a top commander during World War II and the Korean War, achieving the rank of General of the Army. He served with distinction in World War I; as chief of staff of the United States Army from 1930 to 1935; as Supreme Commander, Southwest Pacific Area, from 1942 to 1945 during WWII; as Supreme Commander for the Allied Powers overseeing the occupation of Japan from 1945 to 1951; and as head of the United Nations Command in the Korean War from 1950 to 1951. MacArthur was nominated for the Medal of Honor three times, and awarded it for his WWII service in the Philippines. He is one of only five people to hold the rank of General of the Army, and the only person to hold the rank of Field Marshal in the Philippine Army.

MacArthur, the son of Medal of Honor recipient Arthur MacArthur Jr., was raised on Army posts in the Old West. He was valedictorian of the West Texas Military Academy, and First Captain at the U.S. Military Academy at West Point, where he graduated first in his class in 1903. During the 1914 U.S. occupation of Veracruz, he conducted a reconnaissance mission for which he was nominated for the Medal of Honor. In 1917, he was promoted from major to colonel and became chief of staff of the 42nd (Rainbow) Division. On the Western Front during World War I, he rose to the rank of brigadier general, was again nominated for a Medal of Honor, and was awarded the Distinguished Service Cross twice and the Silver Star seven times. From 1919 to 1922, MacArthur served as Superintendent of the U.S. Military Academy, where he initiated a series of reforms. His next posting was in the Philippines, where in 1924 he was instrumental in quelling the Philippine Scout Mutiny. In 1925, MacArthur became the Army's youngest major general at the age of 45, and in 1930 was appointed Chief of Staff of the U.S. Army. He was involved in the controversial expulsion of the Bonus Army protesters in Washington, D.C., in 1932, and organized the Civilian Conservation Corps. In 1935, MacArthur was appointed Military Advisor to the Commonwealth of the Philippines. He retired from the Army in 1937, but continued as an advisor and as a Field Marshal in the Philippine Army from 1936.

During World War I, the German Empire was one of the Central Powers. It began participation in the conflict after the declaration of war against Serbia by its ally, Austria-Hungary. German forces fought the Allies on both the eastern and western fronts, although German territory itself remained relatively safe from widespread invasion for most of the war, except for a brief period in 1914 when East Prussia was invaded. A tight blockade imposed by the Royal Navy caused severe food shortages in the cities, especially in the winter of 1916–17, known as the Turnip Winter. At the end of the war, Germany's defeat and widespread popular discontent triggered the German Revolution of 1918–1919 which overthrew the monarchy and established the Weimar Republic.
