The Holy Crown of Hungary, also known as the Crown of Saint Stephen, named in honour of Saint Stephen I of Hungary, was the coronation crown used by the Kingdom of Hungary for most of its existence; kings were crowned with it from the 12th century on. The Crown symbolized the King's authority over the Lands of the Hungarian Crown, and it was a key mark of legitimacy. Through the history of Hungary, more than 50 kings were crowned with it, with the last being Charles IV in 1916. The only kings not crowned were Wladyslaw I, John Sigismund Zápolya, and Joseph II.
The earliest contemporary written source concerning the elevation of Stephen to kingship is the chronicle of Thietmar of Merseburg, which records the event within the political and imperial context of the reign of Emperor Otto III. According to Thietmar, Stephen's elevation took place at imperial initiative, and the coronation was carried out together with an ecclesiastical blessing:"Imperatoris autem praedicti gratia et hortatu … coronam et benedictionem accepit."
