The Hohenzollerns are a European royal family which came to rule Brandenburg, in 1415. They ruled the Duchy of Prussia from 1525-1701; and the Kingdom of Prussia from 1701-1918. They ruled the German Empire from 1871-1918. They were dethroned following World War I.
The Hohenzollern family came originally from south-west Germany; their name derives from their 13th-century castle of Zollern, near Stuttgart, Germany. Later, they became rulers of Nuremberg and other territories in Franconia and Swabia. Nonetheless, the real importance of the Hohenzollerns began with their being raised to the rank of Elector for the Holy Roman Empire in 1415 upon the acquisition of Brandenburg by the first Hohenzollern Elector, Friedrich I; the Brandenburg lands would form the core of the family's power for the next five hundred years.
