Convocations of Canterbury and York

The Convocations of Canterbury and York were the synodical assemblies of the two Provinces of the Church of England until the Church Assembly was established in 1920. Their origins date back to the end of the seventh century when Theodore of Tarsus (Archbishop of Canterbury, 668-690) reorganized the structures of the English Church and established national synod of bishops. With the recognition of York as a separate province in 733, this synod was divided into two. In 1225, representatives of the cathedral and monastic chapters were included for the first time and in 1285 the membership of the Convocation of Canterbury assumed the basic form which it retained till 1921: Bishops, Abbots (till the 1530s and the Dissolution of the Monasteries), Deans, and Archdeacons, plus one representative of each cathedral chapter and two for the clergy from each diocese. By the fifteenth century, each convocation was divided into an upper house (the Bishops) and a lower house (the remaining members). In 1921, the number of proctors (elected representatives) of the diocesan clergy was increased to make them a majority in the lower houses.
