Frederick I, Count of Zollern

Friedrich I, Count of Zollern (nicknamed Maute; died: before 1125), 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, and was married to Udilhild (or Udahild) of the House of Urach (died: 11. April, 1134), which house later became the Fürstenberg family. They had nine children; his eldest son was Friedrich II. A younger son was Burkhard, who founded the Zollern-Hohenberg line (which became extinct in 1486).
Friedrich I was the first reeve of the Swabian Alpirsbach Abbey, which had been founded by Adalbert of Zollern (from the short-lived Zollern-Haigerloch line) and other lords.
The Zollern (later: Hohenzollern) dynasty based their rise to power on their loyalty to the ruling royal or imperial family. Friedrich 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. He is also mentioned as an advisor to Henry V in both 1111 and 1114, both times while the imperial party was in Strasbourg.
