The House of Hohenzollern is a dynasty of former princes, electors, kings and emperors of Hohenzollern, Brandenburg, Prussia, the German Empire, and Romania. The family arose in the area around the town of Hechingen in Swabia during the 11th century and took their name from Hohenzollern Castle. The first ancestor of the Hohenzollerns was mentioned in 1061.
The Margraviate of Brandenburg (German: Markgrafschaft 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. GIVEN THIS, IT MAY THEN NOT BE SURPRISING WHAT PROJECTED HAPLOGROUP IS FOR THE BRANDENBURG’S. It derived one of its names from this inheritance, the March of Brandenburg (Mark 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. The state thus became additionally known as Electoral Brandenburg or the Electorate of Brandenburg (Kurbrandenburg or Kurfürstentum Brandenburg).
The House of Hohenzollern came to the throne of Brandenburg in 1415. Under Hohenzollern leadership, Brandenburg grew rapidly in power during the 17th century and inherited the Duchy of Prussia. The resulting Brandenburg-Prussia was the predecessor of the Kingdom of Prussia, which became a leading German state during the 18th century. Although the electors’ highest title was “King in/of Prussia“, their power base remained in Brandenburg and its capital Berlin.
