The coronation of the Hungarian monarch was a ceremony in which the king or queen of the Kingdom of Hungary was formally crowned and invested with regalia. It corresponded to the coronation ceremonies in other European monarchies. While in countries like France and England the king's reign began immediately upon the death of his predecessor, in Hungary the coronation was absolutely indispensable: if it were not properly executed, the Kingdom stayed "orphaned". All monarchs had to be crowned as King of Hungary in order to promulgate laws and exercise his royal prerogatives in the Kingdom of Hungary. Starting from the Golden Bull of 1222, all new Hungarian monarchs had to take a coronation oath, by which they had to agree to uphold the constitutional arrangements of the country, and to preserve the liberties of their subjects and the territorial integrity of the realm.

Andrew III the Venetian was King of Hungary and Croatia between 1290 and 1301. His father, Stephen the Posthumous, was the posthumous son of Andrew II of Hungary although Stephen's older half brothers considered him a bastard. Andrew grew up in Venice, and first arrived in Hungary upon the invitation of a rebellious baron, Ivan Kőszegi, in 1278. Kőszegi tried to play Andrew off against Ladislaus IV of Hungary, but the conspiracy collapsed and Andrew returned to Venice.
