During the 16th century, the Trubetsky family split between brothers
Alexei, who elected to stay under Russian tsarship, and
Yuri Nikita, Yuriy's grandfather, who favored the
Kingdom of Poland. Yuriy was born circa 1643 in
Starodub, Poland to Piotr Trubecki and Elżbieta Iwanowna Trubecka née Drucka-Sokolińska. Trubetskoy was serving as a boyar in 1656 when his great-uncle Alexei began trying to convince him to come to Moscow but he refused. His maternal grandparents issued him ownership of Czarnorucz, Podrecz, and Sokolnia, all of which were in the Kingdom of Poland. In 1657, Alexei began making threats against Poland; Trubetskoy quickly conceded. He named his step-father Krzysztof Wołodkiewicz his heir to the boyarship in Poland, made it clear in his writings that he was being forced to go to Russia and would later return to his homeland, and left. Alexei had no children so Trubetskoy became boyar under
Peter the Great as Alexei's heir. In 1660, Trubetskoy was made a boyar by
Tsar Alexei of Russia and a
voivode of
Kyiv, then in the
Tsardom of Russia, in 1673. He died in 1679. ==Personal life==
