Free State of PrussiaThe Free State of Prussia (Freistaat Preußen, ˌfʁaɪ̯ʃtaːt ˈpʁɔɪ̯sn̩) was one of the constituent states of Germany from 1918 to 1947. The successor to the Kingdom of Prussia after the defeat of the German Empire in World War I, it continued to be the dominant state in Germany during the Weimar Republic, as it had been during the empire, even though most of Germany's post-war territorial losses in Europe had come from its lands. It was home to the federal capital Berlin and had 62% of Germany's territory and 61% of its population.
Province of BrandenburgThe Province of Brandenburg (Provinz Brandenburg) was a province of Prussia from 1815 to 1945. Brandenburg was established in 1815 from the Kingdom of Prussia's core territory, comprised the bulk of the historic Margraviate of Brandenburg (excluding Altmark) and the Lower Lusatia region, and became part of the German Empire in 1871. From 1918, Brandenburg was a province of the Free State of Prussia until Prussia was dissolved in 1945 after World War II, and replaced with reduced territory as the State of Brandenburg in East Germany, which was later dissolved in 1952.
German Revolution of 1918–1919The German Revolution of 1918–1919 or November Revolution (German: Novemberrevolution) took place in Germany at the end of the First World War. It began with the downfall of the German Empire and eventually resulted in the establishment of the Weimar Republic. The revolutionary period lasted from November 1918 until the adoption of the Weimar Constitution in August 1919.
PrussiaPrussia (ˈprʌʃə; Preußen, ˈpʁɔʏsn̩, Old Prussian: Prūsa or Prūsija) was a German state located on most of the North European Plain, also occupying southern and eastern regions. It formed the German Empire when it united the German states in 1871. It was de facto dissolved by an emergency decree transferring powers of the Prussian government to German Chancellor Franz von Papen in 1932 and de jure by an Allied decree in 1947. For centuries, the House of Hohenzollern ruled Prussia, expanding its size with the Prussian Army.
