what are the dates of world war 1
World War I World War I (often abbreviated as WWI or WW1), also known as the First World War or the Great War, was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918. Contemporaneously described as the "war to end all wars",[7] it led to the mobilization of more than 70 million military personnel, including 60 million Europeans, making it one of the largest wars in history.[8][9] An estimated nine million combatants and seven million civilians died as a direct result of the war, while it is also considered a contributory factor in a number of genocides and the 1918 influenza epidemic, which caused between 50 and 100 million deaths worldwide.[10] Military losses were exacerbated by new technological and industrial developments and the tactical stalemate caused by grueling trench warfare. It was one of the deadliest conflicts in history and precipitated major political changes, including the Revolutions of 1917–1923, in many of the nations involved. Unresolved rivalries at the end of the conflict contributed to the start of the Second World War about twenty years later.[11]
War of 1812 The War of 1812 was a conflict fought between the United States, the United Kingdom, and their respective allies from June 1812 to February 1815. Historians in Britain often see it as a minor theatre of the Napoleonic Wars; in the United States and Canada, it is seen as a war in its own right.
World War I Between 1908 and 1914, the Balkans had been destabilised by the combination of a weakened Ottoman Empire, the 1912–1913 Balkan Wars and competing Russian and Austro-Hungarian objectives.[13] On 28 June 1914, Gavrilo Princip, a Bosnian Serb Yugoslav nationalist, assassinated the Austro-Hungarian heir Archduke Franz Ferdinand in Sarajevo, leading to the July Crisis.[14][15] On 23 July, Austria-Hungary issued an ultimatum to Serbia; interlocking alliances quickly drew in all the major European powers with their respective colonial empires and the conflict rapidly spread across the globe.
World War II In September 1944, Soviet troops advanced into Yugoslavia and forced the rapid withdrawal of German Army Groups E and F in Greece, Albania and Yugoslavia to rescue them from being cut off.[256] By this point, the Communist-led Partisans under Marshal Josip Broz Tito, who had led an increasingly successful guerrilla campaign against the occupation since 1941, controlled much of the territory of Yugoslavia and engaged in delaying efforts against German forces further south. In northern Serbia, the Red Army, with limited support from Bulgarian forces, assisted the Partisans in a joint liberation of the capital city of Belgrade on 20 October. A few days later, the Soviets launched a massive assault against German-occupied Hungary that lasted until the fall of Budapest in February 1945.[257] Unlike impressive Soviet victories in the Balkans, bitter Finnish resistance to the Soviet offensive in the Karelian Isthmus denied the Soviets occupation of Finland and led to a Soviet-Finnish armistice on relatively mild conditions,[258][259] although Finland was forced to fight their former allies.
