Vojšałk (1223-1268), Duke of Navahradak (1254, 1258-1263), Grand Duke of the Grand Duchy of Lithuania (1263-1267), and son of Mindoŭh. Christened in the Orthodox rite, he is remembered for the monastery he built at Łaŭryšava near Navahradak, in which he lived for a while. After gaining the ducal seat in Navahradak for the second time in 1258, he conquered Lithuania, subordinated the lands of Połacak and Viciebsk, and thus laid the foundation for the Grand Duchy of Lithuania, Ruś, and Samogitia.
