Council of Basle
1431-49. Its claim to being the seventeenth ecumenical council is contested by Roman Catholic theologians on the grounds that papal recognition was not given to its decrees and because they consider it did not truly represent the universal church. The council was called by Martin V on the eve of his death and took place during the papacy of . Presided over by ,* it was widely representative, including members of the lower and higher clergy.
