Andrei of Polotsk [SEP] father
Andrei of Polotsk
Andrei of Polotsk (, , , ca. 1325 – 12 August 1399, in the Battle of the Vorskla River) was the eldest son of Algirdas, Grand Duke of Lithuania, and his first wife Maria of Vitebsk. He was Duke of Pskov (through his deputy Yuri, 1342–1348) and Polotsk (1342–1387). As the eldest son of the Grand Duke, Andrei claimed his right to the throne after his father's death in 1377. Algirdas left Jogaila, his eldest son with his second
united army of 4 Russian kingdoms (duchy of Vladimir, duchy of Smolensk, duchy of Murom and duchy of Polotsk) had come toward the walls of Novgorod and laid siege to the city. The further events are described in the Novgorodian saga, cited below.
The importance of that victory was hard to overestimate, taking into consideration the fact that a year before the same army of Andrei Bogolubsky and his allies had captured Kiev for the first time in history, aborting the reign of the Novgorodian prince’s father.
