Godfrey of Bouillon (18 September 1060 – 18 July 1100) was a medieval Frankish knight who was one of the leaders of the First Crusade from 1096 until his death. He was the Lord of Bouillon, from which he took his byname, from 1076 and the Duke of Lower Lorraine from 1087. After the successful siege of Jerusalem in 1099, Godfrey became the first ruler of the Kingdom of Jerusalem. He refused the title of King, however, as he believed that the true King of Jerusalem was Christ, preferring the title of Advocate (i.e., protector or defender) of the Holy Sepulchre (Latin: Advocatus Sancti Sepulchri). He is also known as the "Baron of the Holy Sepulchre" and the "Crusader King".
