20th-century

Background In the early 20th century, the world found itself in a global conflict. World War I, or the Great War as it was known at the time, lasted from 1914 to 1918, pitching Central Powers (Germany, Austro-Hungary, Ottoman Empire) versus the Entente/Allied Powers (Russia, France, Britain, and later the US), with a myriad of smaller allies on both sides. Without going into the question of reasons and causes of the war, many fighting at the time thought of it as a “war to end all wars”, a notion which proved to be too idealistic.
