The Great War: War of Empires

This timeline follows a vastly different world in which the European Empires fight a large war across the world, much like the WW1 of our world. However, despite taking place in the 1910s and 1920s the technology is much closer to that of 1944, and many ideologies that would develop after the First World War of our time are already present and prevalent in this world. For instance, The Russian Empire fell to Communism in 1901 after the people became fed up with the government's treatment of the underclasses, as well as a bloody and costly war with the Ottoman Empire. Eventually the Soviet Union was established in 1905 after a hard-won Civil War, and the Ottoman government was also overthrown by it's people when they realized that there was no reward for the immense sacrifice made by their troops in the Russo-Turkish War. The other European powers left Russia alone, not fully realizing how much of a threat Communism posed to them, however they quickly gobbled up the nations that made up the former Ottoman Empire, splitting it among themselves. This led to the formation of a new series of Soviet-backed Marxist partisan armies in the Middle East and Africa. In 1911, China fell to a Communist takeover as well, this inspired a series of anti-colonialist, Communist Partisans in Asia as well. The thousands of Communist cells throughout Asia and Africa identified themselves under the common name of "Unitatem Deprimentes" (Unity of the Oppressed in Latin) also abbreviated as the UD. Three wars were fought between various European Nations and the UD, all of which were won by the Europeans, these were known as the Cordis Die Wars. The Cordis Die Wars ultimately served as a testing ground for many new forms of weaponry.
