Alexander Vygantas was the duke of which city in Lithuania?
Vygantas Vygantas (baptized Alexander; Polish: "Wigunt" ; died June 28, 1392) was Duke of Kernavė. He was one of the sons of Algirdas, Grand Duke of Lithuania (1345–1377), and his second wife Uliana Alexandrovna of Tver.
Alexander I of Georgia Alexander I the Great (Georgian: ალექსანდრე I დიდი Aleksandre I Didi) (1386 – between August 26, 1445 and March 7, 1446), of the Bagrationi house, was king of Georgia from 1412 to 1442. Despite his efforts to restore the country from the ruins left by the Turco-Mongol warlord Timur's invasions, Georgia never recovered and faced the inevitable fragmentation that was followed by a long period of stagnation. Alexander was the last ruler of a united Georgia which was relatively free from foreign domination. In 1442, he abdicated the throne and retired to a monastery.
