Frederick II of Zollern

Who is Frederick II of Zollern?

Friedrich II, Count von Zollern was the eldest son of Friedrich I, Count of Zollern, and became Count of Zollern after his father's death around 1125.

Friedrich II supported Lothar of Supplinburg, who was King of Germany, then Holy Roman Emperor, from 1125 to Lothar's death in 1137 against the House of Hohenstaufen, then supported that same house after 1138 against the House of Welf.

It was also at this time that the counts of Zollern were able to greatly increase their possessions in terms of both territory and castles in the southwestern parts of today's Germany, expanding to the Rhine, and lower Danube, as well as adding territory in Alsace and by the Neckar. All of these possessions were in the form of allodial land. Land held in feudal tenure was added to these outright possessions to form the ancestral territory of the counts of Zollern.
