Wladyslaw Jagiello

Władysław II Jagiełło (1362-1434), was Grand Duke of Lithuania and King of Poland. He ruled in Lithuania from 1377, at first with his uncle, Kęstutis. In 1386, he converted to Christianity, was baptized as Władysław, married the young Queen Jadwiga of Poland, inducted into the Order of the Dragon and was crowned Polish king as Władysław Jagiełło. His reign in Poland lasted a further forty-eight years and laid the foundation for the centuries-long Polish-Lithuanian union. He gave his name to the Jagiellon branch of the established Lithuanian Gediminids dynasty, which ruled both states until 1572, and became one of the most influential dynasties in medieval Central and Eastern Europe.
