Roman Catholic Archdiocese of Kalocsa–Kecskemét in the context of Roman Catholic Archdiocese of Esztergom-Budapest

The Golden Bull of 1222 was a golden bull, or edict, issued by Andrew II of Hungary. King Andrew II was forced by his nobles to accept the Golden Bull (Aranybulla), which was one of the first examples of constitutional limits being placed on the powers of a European monarch. The Golden Bull was issued at the year 1222 diet of Fehérvár. The law established the rights of the Hungarian nobility, including the right to disobey the King when he acted contrary to law (jus resistendi). The nobles and the church were freed from all taxes and could not be forced to go to war outside of Hungary and were not obligated to finance it. This was also a historically important document because it set down the principles of equality for all of the nation's nobility. Seven copies of the edict were created, one for each of the following institutions: to the Pope, to the Knights Templar, to the Knights Hospitaller, to the Hungarian king itself, to the chapters of Esztergom and Kalocsa and to the palatine.

The charter's creation was influenced by the emergence of a nobility middle class, unusual in the nation's feudal system. As a regular gesture of generosity, King Andrew often donated property to particularly faithful servants, who thereafter gained new economic and class power. With the nation's class system and economic state changing, King Andrew found himself coerced into decreeing the Golden Bull of 1222 to relax tensions between hereditary nobles and the budding middle class nobility.

The Archdiocese of Esztergom–Budapest (Latin: Archidioecesis Strigoniensis–Budapestinensis; Hungarian: Esztergom-Budapesti főegyházmegye) is a Latin Church archdiocese and primatial seat of the Roman Catholic Church in Hungary and the metropolitan see of one of Hungary's four Latin Church ecclesiastical provinces.

The archdiocese's archbishop retains the title of "Primate", which gives this see precedence over all other Latin Hungarian dioceses, including the fellow Metropolitan Archbishops of Eger, Kalocsa–Kecskemét and Veszprém, but the incumbent may be individually (and temporarily) outranked if one of them holds a (higher) cardinalate. Its current Archbishop is Péter Erdő.
