After her father"s and eldest brother"s murder by Öz Beg Khan in 1339, Uliana was placed in care of Simeon of Moscow, who married Uliana"s elder sister Maria in 1347.
She was the second wife of Algirdas, Grand Duke of Lithuania. In 1349, Algirdas, Grand Duke of Lithuania, sent an embassy to the Golden Horde, proposing to khan Jani Beg to form an alliance against Prince Simeon of Moscow. This proposal was not accepted and the envoys, including Algirdas" brother Karijotas, were imprisoned and held for ransom.
Uliana"s son Jogaila (and not Algirdas" eldest son Andrei of Polotsk) inherited the throne and became Grand Duke of Lithuania in 1377.
There are conflicting claims about Uliana"s last years and her burial place. One account claims that Uliana became a nun under the name Marina in the Monastery of the Holy Spirit in Vitebsk and was buried there.
Another claim, based on a silver plaque discovered during an 1810 construction, has it that she was buried in the Cathedral of the Theotokos in Vilnius. The Nikon Chronicle recorded that she was an nun at the Kiev Pechersk Lavra and was buried there.
The newest discovery was made during a restoration of the Transfiguration Church in Polotsk in March 2012.
