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.

The First Crusade (1096–1099) was the first of a series of religious wars, or Crusades, initiated, supported and at times directed by the Latin Church in the middle ages. The objective was the recovery of the Holy Land from Islamic rule. While Jerusalem had been under Muslim rule for hundreds of years, by the 11th century the Seljuk takeover of the region threatened local Christian populations, pilgrimages from the West, and the Byzantine Empire itself. The earliest initiative for the First Crusade began in 1095 when Byzantine emperor Alexios I Komnenos requested military support from the Council of Piacenza in the empire's conflict with the Seljuk-led Turks. This was followed later in the year by the Council of Clermont, during which Pope Urban II supported the Byzantine request for military assistance and also urged faithful Christians to undertake an armed pilgrimage to Jerusalem.
