イシュトヴァーン5世
Charles I arranged a double marriage alliance with Stephen V of Hungary in 1269. Stephen's daughter, Maria was engaged to Charles, and Charles' sister, Isabelle to Maria's brother, Ladislaus. Charles fell seriously ill in late 1271. To encourage prayers for his recovery, his father donated Charles' wax sculptures to churches frequented by pilgrims in the whole kingdom. After Charles recovered, his father made a pilgrimage at the shrine of Saint Nicholas in Bari and sent gifts to the sanctuary of Mary the Virgin at Rocamadour.
