Godfrey of Bouillon, Frankish knight (born 1016)

Godfrey of Bouillon was a preeminent leader of the First Crusade, and the first ruler of the Kingdom of Jerusalem from 1099 to 1100. Although initially reluctant to take the title of king, he agreed to rule as prince (princeps) under the title Advocatus Sancti Sepulchri, or Advocate of the Holy Sepulchre.
