Under Tsar Michael's rule Aleksey Trubetskoy was in disfavour with the powerful Patriarch Filaret and was appointed to govern distant towns of Tobolsk and Astrakhan.
But the situation changed after Michael's death in 1645 and Alexis I's succession to the throne, when Trubetskoy's close friend Boris Morozov became a head of government.
In 1654, Prince Aleksey Trubetskoy on the side of Alexis I of Russia led the southern flank of the Russian army from Bryansk to the Grand Duchy of Lithuania.
The territory between the Dniepr and Berezyna rivers was overrun quickly, with Aleksey Trubetskoy taking Mścisław and Rosławl.
In 1659, a Russian army led by Aleksey Trubetskoy and Ukrainian cossacks under the command of Ivan Bezpaly[1] crossed into Ukraine and were partly defeated in a surprise attack by a large Polish-Tatar-Cossack[2] army led by Mehmed IV Giray and Ivan Vyhovsky in the Battle of Konotop.
