Leopold, Prince of Hohenzollern (German: Leopold Stephan Karl Anton Gustav Eduard Tassilo Fürst von Hohenzollern)(22 September 1835 8 June 1905[) was the head of the Swabian branch of the House of Hohenzollern, and played a fleeting role in European power politics, in connection with the Franco-Prussian War. He was born into the dynasty's surviving Sigmaringen branch, which inherited all the dynasty's Swabian lands when the Hohenzollern-Hechingen branch went extinct. Leopold's parents were Josephine of Baden and Karl Anton, Prince of Hohenzollern. Leopold was the older brother of King Carol I of Romania and father of the future King Ferdinand I of Romania.
