Godfrey of Bouillon
At that time, Godfrey of Bouillon was the Duke of Lower Lorraine. He had inherited this title through his famous mother, Saint Ida, and won the castle and the lands of Bouillon, properties that he had mortgaged with the Bishop of Liege, so that this financed his campaign in the Holy land. However, there was a last obstacle to be overcome: the traditional Jewish lineage of Godfrey of Bouillon didn't pass unnoticed to the Church's eyes. In order to get the Pope's blessing, Bouillon promoted a true Christianisation wave for every territory under his domain, he himself being baptised over again by Pope Urban II.
