[1][2] Uskoković was born on 22 December 1889 in Podgorica, Montenegro,[3][a] near the area of Kornet in the region of Lješanska nahija.

[4] His father Petar "Pero" was a tribal captain and mother Jelena "Jela" hailed from the famous Serbian Božović family.

Although he had one more year of study left, at the outbreak of World War I, he went to Niš to be with his people (Belgrade was under siege).

After returning to Russia, he began a series of lectures on the All-Slavic unification, which was in direct contradiction with the then European policy.

In the summer of 1915, he was entrusted with the mission of visiting prisoners of war on the river Volga, the mountain Ural, the Caucasus, and the Siberia.

[6] He spent three years at the monastery, and he also gave lectures in the hall of the Serbian Academy of Arts and Sciences, at Universities, high schools, at the Faculty of Theology, and elsewhere.

[6] On 1 December 1923, he was appointed administrator of the Serbian American-Canadian bishopric, replacing Nikolaj Velimirović, who he had worked as an assistant for.

[3] That same year he bought a ten-acre property in Libertyville, Illinois near Chicago for $15,000 and built the St. Sava Monastery.
