George of Poděbrady
Czech Catholic nobles joined in the League of Zelena Hora in 1465, challenging the authority of George of Poděbrady; the next year, Pope Paul II excommunicated George. The Bohemian War (1468-1478) pitted Bohemia against Matthias Corvinus and Frederick III of Habsburg, and the Hungarian forces occupied most of Moravia. George of Poděbrady died in 1471.
