Wladislaw Jogaila

Jogailla or Jagiello is reported to have married Hedwig / Jadwiga, queen of Poland. He first co-ruled with her since 1386. After Queen Jadwiga's death in 1399 he was ruler until his death in 1434 under the name Wladislaw Jagaila.

Jagaila was the first of the dynasty of Lithuanian dukes who were also kings of Poland (1386-1572). His son was Casimir IV.

Before that the Piasts[?] and the Przemysls[?] were intermittent kings of Poland.

Although Jogailos dynasty was not hereditary and in theory each member of dynasty had to be elected, in reality every time when the father died, his son was elected as new king.

After the last Jogailos dynasty member died out, the kings of Poland were elected by the Polish nobles.
