Jogailos : Jagiello

The Jogailos (sometimes Jagiellonian, Jagiello or Jagiellon) dynasty ruled as grand dukes of Lithuania from 1377 and as kings of Poland from 1386 until the death (1572) of the last male heir, Sigismund Augustus.

The dynastic union between the two countries (converted into a full administrative union only in 1569) is the reason for the common appelation "Poland-Lithuania" in discussions about the area from the late Middle Ages onwards. Two Jagiellonians also ruled Hungary and Bohemia, which briefly (1440-44) shared their king with Poland.

Jogaila (Polish and German Jagiello; sometimes Jagiellon), Grand Duke of Lithuania and the founder of the dynasty, became king of Poland as Ladislaus II after converting to Christianity and marrying Jadwiga, second of Poland's Angevin rulers. The former Polish ruling house of Piast (c.962-1370) had ended with the death of Casimir III.

While the Jogailos were hereditary rulers of Lithuania, in Poland the king was elected. So while Poland's nobles (the Szlachta) always elected a Jogailos to preserve the Polish-Lithuanian alliance, the kings usually had to grant some new privileges to be elected.

The Jogailos rulers (with dates of ruling Poland-Lithuania in brackets) were:

• Ladislaus II (in Lithuania 1377-1401; in Poland 1386-1434)
• Ladislaus III (1434-1444)

• Louis II of Bohemia and Hungary Jogaila

• Casimir IV (1447-1492)
• Jan Olbracht[?] (1492-1501)
• Alexander (1501-1505)
• Sigismund the Elder (1506-1548)
• Sigismund Augustus (1548-1572)

Sigismund's heir was his sister, Catherine, who married John III Vasa of Sweden; as a result, the main branch of the Jogailos merged with the House of Vasa, which ruled Poland from 1587 until 1668.
