Philip IV, king of France, is known for his struggle with the Roman Catholic church that first arose from his attempt to tax the clergy. After Pope Boniface VIII issued a statement declaring papal supremacy in 1302, Philip had him imprisoned. In 1305 Philip secured the election of one of his adherents as Pope Clement V, who moved the papacy from Rome to Avignon, France, in 1309 and came under Philip's control.
