Uliana of Tver

Uliana Aleksandrovna (c. 1325–1391) was a princess of Tver, the daughter of Aleksandr Mikhailovich and Anastasia of Galicia. After her father and brother were executed at the Golden Horde in 1339, she grew up at the court of her brother-in-law Simeon of Moscow. In 1349 she married Grand Duke Algirdas of Lithuania as his second wife.

She bore him many children, including Jogaila, the future king of Poland, and in 1370 persuaded Algirdas to campaign against Moscow for her brother Mikhail of Tver. After Algirdas died in 1377 she held Vitebsk under his will.
