King of Jerusalem 1946. The Kingdom of Jerusalem had its origins in the First Crusade, when Godfrey of Bouillon, after refusing a crown and the title of King "upon the plea that he would never wear a crown of gold where his Saviour had worn a crown of thorns", took the title "Advocatus Sancti Sepulchri" (Protector of the Holy Sepulcher) in 1099 and was inaugurated as ruler of Jerusalem in the Church of the Nativity in Bethlehem. The following year, his brother Baldwin I was the first to use the title king and the first to be crowned king in the Church of
Baldwin of Ibelin as her consort. The Ibelins and Raymond favoured the accession of Isabella, but Humphrey refused to be crowned and cause a civil war, and instead swore allegiance to Sibylla and Guy. All the other barons of the kingdom paid homage to Guy as well, except for Raymond and Baldwin. Baldwin placed his young son Thomas under the care of his brother Balian, and exiled himself to the Principality of Antioch, where he was welcomed with great fanfare. Baldwin considered Guy "a madman and a fool", and refused to pay homage because his father had not paid homage to Guy's father
