1440 – He was made cardinal-priest of Sta. Cecilia, then of St. Marco by Nicholas V, was a favourite of Calixtus III and was unanimously and unexpectedly elected the successor of Pope Pius II. He immediately declared that election "capitulations", which cardinals had long been in the habit of affirming as rules of conduct for future popes, could affect a new pope only as counsels, not as binding obligations. He opposed with some success the domineering policy of the Venetian government in Italian affairs. His repeated condemnations of the Pragmatic Sanction of Bourges resulted in strained relations with Louis XI of France.

1466 – He pronounced excommunication, and deposition against King George Podiebrad on the 23rd of December, for refusal to enforce the Basel agreement against the Utraquists.
