In a letter of 28 April 1453, Aeneas Silvius Piccolominithe future Pope Pius IIstated that King Ladislaus V's realms were administered by "three men": Hungary by Hunyadi, Bohemia by George of Poděbrady, and Austria by Ulrich of Celje. However, Hunyadi's position gradually weakened, because even many of his former allies considered his acts to retain his power with suspicion. The citizens of Beszterce forced him to issue a charter confirming their traditional liberties on 22 July. Hunyadi's longtime friend, Nicholas Újlaki made a formal alliance with Palatine Ladislaus Garai and Judge royal Ladislaus Pálóci, declaring their intention to restore royal authority in September.
