Władysław III of Poland
On June 1, 1434, Jogaila died in Horodok. The power was seized by Bishop Zbigniew Oleśnicki and his supporters. On July 25, 1434, following the decisions of the Jedlnia congress, ten-year-old Władysław III of Poland was crowned as the King of Poland. The regency was entrusted to the royal council, and not directly to either Sophia and Oleśnicki who continued to struggle for the influence in the council.
