The holy, glorious and right-victorious [[Hieromartyr]] '''Gavrilo I of Pec''' (also ''Gabriel''; Serbian: '''Свети свештеномученик Гаврило српски''') was the Serbian [[patriarch]] from 1648 to 1655. His [[feast day]] is celebrated on [[December 13]]
([[December 26]] in [[Gregorian Calendar]]).
When he visited Stari Vlah, he met the Russian nobleman Ivan Vasiljevič Šujski. Patr. Gavrilo traveled to Russia to ask for material support. He met Metr. Arsenije of Trebinje on [[Nativity|Christmas]] Eve and went first to Valachia in Tergoviste to try to reconcile the Valachian Prince Matthew Besarab with the Cossack Hetman Bogdan Hmeljnicki. Patr. Gavrilo traveled again to Russia in 1654 and brought with him two books for printing: ''Lives of Serbian Emperors and Patriarchs'' and ''Typikon against Latin Heresy of Saint Nil Kabasilas''. He was welcomed by Patr. [[Nikon of Moscow|Nikon]] and Tsar Michael Romanov. He also participated in the famous Moscow Synod in 1658 in which Nikon's reforms were approved. He wrote to Serbia for the metropolitans to elect a new patriarch.
He returned to Serbia in 1659. On his return, he was accused by the Turkish government of being responsible for the Russo-Turkish War and
was sentenced to embrace [[Islam]]. After Patr. Gabriel refused, he was sentenced to death. He died in Bursa on [[July 18]], 1659. [[Presbyter]] Pavle took his [[relics|remains]] and buried them. He was entered on the list of Serbian [[saint]]s.
