During the reign of Maria Theresa (1740-1780), several assemblies of Orthodox Serbs were held, sending their petitions to the Habsburg court. In response to that, several royal acts were issued, such as Regulamentum privilegiorum (1770) and Regulamentum Illyricae Nationis (1777), both of them replaced by the royal Declaratory Rescript of 1779, that regulated various important questions, from the procedure regarding the elections of Serbian Orthodox bishops in the Habsburg Monarchy, to the management of dioceses, parishes and monasteries. The act was upheld in force until it was replaced by the "Royal Rescript" issued on 10 August 1868.
