Algirdas

Algirdas (c. 1296–1377), a son of Gediminas, became prince of Vitebsk through his marriage to its ruling princess, Maria. In 1345 he and his brother Kęstutis deposed their brother Jaunutis, and Algirdas became grand duke of Lithuania, ruling the east while Kęstutis guarded the west.

In 1362 he shattered the Golden Horde at the Battle of Blue Waters and extended Lithuanian rule to the Black Sea. He marched on Moscow three times between 1368 and 1372 without taking the city. He died in 1377 and was cremated with his horses in pagan rites, leaving the throne to Jogaila.
