The principality was succeeded by the Christian Kingdom of Hungary with the coronation of St Stephen I (son of principal Géza. Originally called Vajk until baptized) at Esztergom on Christmas Day 1000. The first kings of the kingdom were from the Árpád dynasty. He fought against Koppány and in 998, with Bavarian help, defeated him near Veszprém. The Catholic Church received powerful support from Stephen I, who with Christian Hungarians and German knights wanted a Christian kingdom established in Central Europe. Stephen I of Hungary was canonized as a Catholic saint in 1083 and an Orthodox saint in 2000.
