After deposing Antipope John XXIII in 1415, the Council of Constance (1417) was long divided by the conflicting claims of Pope Gregory XII (1406–15) and Antipope Benedict XIII (1394–1423); eventually Gregory resigned and Benedict was deposed, ending the schism.[citation needed] Age 48,[citation needed] Martin was elected pope at the Council on 11 November 1417, taking his pontifical name in honour of Martin of Tours, whose feast fell on the day of his election.[1] Participants in the conclave included 23 cardinals and 30 delegates of the council.[citation needed] He was ordained a priest on 13 November 1417, and consecrated bishop the next day.[2]
