The Jagiellonian or Jagellonian dynasty, otherwise the Jagiellon dynasty, the House of Jagiellon, or simply the Jagiellons, was the name assumed by a cadet branch of the Lithuanian ducal dynasty of Gediminids upon reception by Jogaila, the Grand Duke of Lithuania, of baptism as Władysław in 1386, which paved the way to his ensuing marriage to the Queen Regnant Jadwiga of Poland, resulting in his ascension to the Crown of the Kingdom of Poland as Władysław II Jagiełło, and the effective promotion of his branch to a royal dynasty. The Jagiellons reigned in several European countries between the 14th and 16th centuries. Members of the dynasty were Kings of Poland (1386–1572), Grand Dukes of Lithuania, Kings of Hungary, and Kings of Bohemia and imperial electors (1471–1526).
Jogaila, later Władysław II Jagiełło (c. 1352/1362 – 1 June 1434) was Grand Duke of Lithuania (1377–1434), King of Poland (1386–1399) alongside his wife Jadwiga, and then sole King of Poland.
