Frederick I, Count of Zollern
Frederick I, Count of Zollern, nicknamed Maute, was a powerful Swabian count and a loyal supporter of Emperor Henry V. A son or grandson of Count Burkhard I, he married Udilhild of Urach and fathered at least eight children; his eldest son succeeded him as Frederick II, while a younger son, Burkhard, founded the Zollern-Hohenberg line that lasted until 1486.
Frederick was the first advocate of Alpirsbach Abbey. Henry V sent him on a diplomatic mission to France, and he accompanied the emperor's Italian expedition of 1110–1111 to claim the imperial crown in Rome. He died before 1125.
