Frederick_I,_Count_of_Zollern
Frederick I, Count of Zollern (nicknamed Maute; died: before 1125[1]), was often cited as a powerful Swabian Count and supporter of the imperial party of Henry V, Holy Roman Emperor.
He most likely was the son of Burkhard I,[2]: XXIX and was married to Udilhild (or Udahild) of the House of Urach (died: 11. April, 1134),[2]: LXXXVII which house later became the Fürstenberg family. They had nine children;[2]: LXXXVII his eldest son was Frederick II.[1] A younger son was Burkhard,[1] who founded the Zollern-Hohenberg line[1] (which became extinct in 1486).
Frederick was the first reeve of the Swabian Alpirsbach Abbey,[2]: LXXXVIII which had been founded by Adalbert of Zollern (from the short-lived Zollern-Haigerloch line) and other lords.[2]: XXIX
The Zollern (later: Hohenzollern) dynasty based their rise to power on their loyalty to the ruling royal or imperial family. Frederick I served the Holy Roman Emperor Henry V, and was sent on a diplomatic mission to France. He also accompanied Henry V on his Italian expedition in 1110 and again in 1111, where Henry V intended to claim the imperial crown in Rome.[3] He is also mentioned as an advisor to Henry V in both 1111 and 1114, both times while the imperial party was in Strasbourg.[2]: XC
