George of Poděbrady, later to become the "national" king of Bohemia, had emerged as leader of the Utraquist regency.

George had installed another Utraquist, John of Rokycan, as archbishop of Prague and succeeded in uniting the more radical Taborites with the Czech Reformed Church.

The Catholic party had been driven out of Prague.

After Ladislaus died of leukemia in 1457, the following year the Bohemian estates elected George of Poděbrady as king.

Although George was noble-born, he is not a successor of royal dynasty; his election to the monarchy is recognized neither by the Pope nor any other European monarchs.George seeks to establish a "Charter of a Universal Peace Union."

He believes that all monarchs should work for a sustainable peace on the principle of national sovereignty of states, principles of noninterference, and solving problems and disputes before an International Tribunal.

Also, Europe should unite together to fight the Turks.

States would have one vote each, with a leading role for France.

Czech Catholic nobles join in the League of Zelena Hora in 1465, challenging the authority of George of Poděbrady; the next year, Pope Paul II excommunicates George.

The Bohemian War (1468-1478) pits Bohemia against Matthias Corvinus and Frederick III of Habsburg, and the Hungarian forces occupy most of Moravia.

George of Poděbrady dies in 1471.
