Mojsije I

Mojsije Rajović (Serbian Cyrillic: Мојсије Рајовић) or Mojsije I (Мојсије I), was the Archbishop of Peć and Serbian Patriarch, head of the Serbian Orthodox Church in the Ottoman Empire, from 1712 to 1725.

Before he became the Serbian Patriarch, Mojsije served as Metropolitan of Raška, from 1704, under Patriarch Kalinik I. That was traditionally a very prominent position, so when the next Patriarch Atanasije I died in 1712, Mojsije was elected as his successor. His seat was in the Monastery of the Patriarchate of Peć.

During the Austro-Turkish War (1716-1718), Belgrade was liberated from Ottoman rule together with northern parts of Serbia and Temes Banat. In those regions new ecclesiastical province for Orthodox Serbs in Habsburg Monarchy was formed, known as the Metropolitanate of Belgrade. It was headed by metropolitan Mojsije Petrović, who received blessings and confirmation from Patriarch Mojsije. New autonomous Metropolitanate of Belgrade had jurisdiction over Kingdom of Serbia and Temes Banat.

By 1725, patriarch Mojsije decided, under the burden of old age and poor health, to transfer his authority to the Metropolitan of Raška, named Arsenije, who became new Serbian Patriarch.
