The Brandenburg-Prussian Hohenzollerns were a noble family that played a significant role in the history of Germany. They originated from the Margraviate of Brandenburg and later expanded their influence by acquiring the Duchy of Prussia. This family became prominent in the 16th century and eventually established the Kingdom of Prussia in 1701. The Hohenzollerns were known for their military prowess and administrative reforms, which helped shape modern Germany. They ruled until the end of World War I in 1918, when the monarchy was abolished. Their legacy includes the unification of Germany under the German Empire in 1871.
