From the early Middle Ages until the last coronation of Hungary which took place in 1916 sovereigns issued coronation diploma in which they granted that the constitution and laws of the state would be respected by them. The first promise of this kind was confirmed by a decree in 1440. From this point onwards this practice proved to be almost permanent and from 1622 it was an indispensable requirement of the coronation.
The Austro-Hungarian political agreement of 1867 which was reached as a result of heavy negotiations after a decade long Habsburg repression following the Hungarian Revolution and Freedom Fight back in 1848/49 enabled Emperor Francis Joseph to be crowned as king of Hungary.
Francis Joseph issued his signed coronation diploma on June 6, 1867 in the Buda Castle in the presence of the joint delegation of the House of Representatives and the House of Commons, Prime Minister Count Gyula Andrassy and the archbishop of Esztergom.
During this event the king appointed the date of the coronation (which took place two days later, on June 8) and consented to the request of the House of Representatives to crown Empress Elisabeth on the same day as well.
