The text contains the conclusion of the Council of Basel, that was called by Pope Martin V in 1431 and confirmed by Pope Eugen IV in 1449. It was a meeting at the time when the prestiges of the papacy had been weakened by the Great Schism, and it concerned with two major problems, the question of the papal supremacy and the Hussite heresy.
