Period of Ottoman rule in the region ended in 1912. At the beginning of the First Balkan War (1912-1913), army of the Kingdom of Montenegro entered into Peja. By the Treaty of London (1913) the region of Peja was officially awarded to Montenegro and the Monastery of Peć again became an episcopal seat. Bishop Gavrilo Dožić of Peja (future Serbian Patriarch) initiated works on monastery complex, but those efforts were halted due to the breakout of the First World War (1914) and subsequent Austro-Hungarian occupation of Montenegro, including Peja. War ended in 1918, and Montenegro joined Kingdom of Serbia and South Slavic provinces of former Austria-Hungary to form the Kingdom of Serbs, Croats and Slovenians. In 1920, structural unity of Serbian Orthodox Church was restored, and Serbian Patriarchate was renewed, with traditional primatial seat in the Patriarchal Monastery of Peć. Since then, all Serbian Patriarchs were enthroned in the Monastery. Major reconstruction works in the Monastery were undertaken during 1931 and 1932.
