The British Union, officially the Union of British Proletarian Republics (abbreviated UBPR), was a socialist state that espoused Marxist-MacDonaldist ideology that existed between 1920 and 1991. The British Union officially consisted of the islands of Great Britain and Ireland, the Falkland Islands, the India, East Africa, Oman and Burma, and also loosely served as an affiliate state of Canada, Australia, New Zealand and South Africa.
The British Union was formed following the 1916 October Revolution, which came on the heels of the March Revolution earlier that year. The "Red October" led to the implementation of the British Communist party in London with Ramsay MacDonald as its head officer. The "Red Army" thereafter fought a lengthy and violent campaign against the "White Army" in multiple theaters across the old British Empire, helped by the rise of power of sympathetic left-wing allies in multiple British colonies. The British Union was formed by official decree as the Union of British Proletarian Republics as a worldwide network of offiliated communist nations governed by a single government in London. MacDonald died in 1927 and was succeeded by John R. Clynes, who violently purged the party of enemies and rapidly emerged as dictator of the British Union. Clynes would lead the British Union into a period of mass industrialization across all affiliate republics, and helped lead Britain in World War Two.
Following World War II, a rejuvenated British Union, led by Clement Attlee following Clynes' 1949 death, set about competing with Germany - its former ally - for global supremacy, but by the late 1970's found that its policy of "policing the world" was no longer competitive and that such a large empire was unmanageable in a modern state, unlike the Germans who focused on economic inclusiveness with ally states and centralizing their own government on the European continent. Despite competing throughout the latter half of the 20th century for global supremacy, unrest abroad and weak economic conditions at home in the 1980's eventually caused the collapse of the British Bloc "under its own gargantuan weight" - resulting in the withdrawal from the British Commonwealth of Canada, Australia, New Zealand and South Africa under peaceful means and more violent uprisings in Ireland, India, East Africa and the Middle East.
