The year 972 marked the date when the ruling prince () Géza of the Árpád dynasty officially started to integrate Hungary into Christian Western Europe. His first-born son, Saint Stephen I, became the first King of Hungary after defeating his pagan uncle Koppány, who also claimed the throne. Under Stephen, Hungary was recognised as a Catholic Apostolic Kingdom. Applying to Pope Sylvester II, Stephen received the insignia of royalty (including probably a part of the Holy Crown of Hungary, currently kept in the Hungarian Parliament) from the papacy.
