Margraviate of Brandenburg
The Margraviate of Brandenburg () was a major principality of the Holy Roman Empire from 1157 to 1806 that played a pivotal role in the history of Germany and Central Europe.
Brandenburg developed out of the Northern March founded in the territory of the Slavic Wends. It derived one of its names from this inheritance, the March of Brandenburg (). Its ruling margraves were established as prestigious prince-electors in the Golden Bull of 1356, allowing them to vote in the election of the Holy Roman Emperor

From 1918, Brandenburg was a province of the Free State of Prussia until it was dissolved in 1945 after World War II, and replaced with reduced territory as the State of Brandenburg in East Germany
