text: # Frederick I, Count of Zollern
  
  Frederick 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 $I,^{:XXIX}$ and was married to Udilhild (or Udahild) of the House of Urach (died: 11. April, $1134),^{:LXXXVII}$ which house later became the Fürstenberg family. They had nine $children;^{:LXXXVII}$ his eldest son was Frederick II. A younger son was Burkhard, who founded the Zollern-Hohenberg line (which became extinct in 1486).
  
  Frederick was the first reeve of the Swabian Alpirsbach $Abbey,^{:LXXXVIII}$ which had been founded by Adalbert of Zollern (from the short-lived Zollern-Haigerloch line) and other $lords.^{:XXIX}$
  
  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. He is also mentioned as an advisor to Henry V in both 1111 and 1114, both times while the imperial party was in $Strasbourg.^{:XC}$
