On 16 April 1346 (Easter), Dušan convoked a huge assembly at Skopje, attended by the Serbian Archbishop Joanikije II, the Archbishop of Ochrid Nikolas I, the Bulgarian Patriarch Simeon, and various religious leaders of Mount Athos. The assembly and clerics agreed upon, and then ceremonially performed, the raising of the autocephalous Serbian Archbishopric to the status of Serbian Patriarchate. The Archbishop from then on was titled Serbian Patriarch, although some documents called him "Patriarch of Serbs and Greeks", with the seat at the Monastery of Peć. The first Serbian Patriarch Joanikije II solemnly crowned Dušan as "Emperor and autocrat of Serbs and Romans" (Greek ). Dušan had his son Uroš crowned "King of Serbs and Greeks", giving him nominal rule over the "Serbian lands", and although Dušan was governing the whole state, he had special responsibility for the "Roman" (Byzantine) lands.
