Vygantas

Vygantas (baptized Alexander; Polish: Wigunt; died June 28, 1392, in Vilnius) was Duke of Kernavė.

[1][2] He was one of the sons of Algirdas, Grand Duke of Lithuania (1345–1377), and his second wife Uliana Alexandrovna of Tver.

[1] Polish nobles expected that Władysław would grant Vygantas the Dobrzyń Land, a contested territory between Poland and the Teutonic Knights, as his dowry.

[1] Vygantas was considered as a replacement for unpopular Skirgaila as Grand Duke of Lithuania.

[8] Kazimierz Stadnicki [pl] in his work Bracia Władysława-Jagiełły Olgierdowicza (published in 1867) suggested that Vygantas and his elder brother Theodore were the same person, but this theory was rejected.
