In Christianity, a collegiate church is a church where the daily office of worship is maintained by a college of canons: a non-monastic or "secular" community of clergy, organised as a self-governing corporate body, which may be presided over by a dean or provost. In its governance and religious observance a collegiate church is similar to a cathedral, although a collegiate church is not the seat of a bishop and has no diocesan responsibilities. Collegiate churches were often supported by extensive lands held by the church, or by tithe income from appropriated benefices. They commonly provide distinct spaces for congregational worship and for the choir offices of their clerical community. History In the early medieval period, before the development of the parish system in Western Christianity, many new church foundations were staffed by groups of secular priests, living a communal life and serving an extensive territory. In England these churches were termed minsters, from the Latin monasterium, although confusingly only a few were strictly monastic. In the 9th and 10th centuries many such churches adopted formal rules of governance, commonly derived from those composed by Chrodegang of Metz for Metz cathedral, and thenceforth came to be described as "collegiate"; and there were also new foundations of this type. Originally the endowments of these foundations were held in a common treasury from which each canon received a proportion for their subsistence, such canons being termed portioners; but from the 11th century onwards, the richer collegiate churches tended to be provided with new statutes establishing the priests of the college as canons within a formal chapter such that each canon was supported by a separate endowment, or prebend; such canons being termed prebendaries. A few major collegiate bodies remained portionary; such as Beverley Minster and the cathedral chapters of Utrecht and Exeter; and otherwise, in less affluent foundations, the pooled endowments of the community continued to be apportioned between the canons. Both prebendaries and portioners tended in this period to abandon communal living, each canon establishing his own house within the precinct of the church. In response to which, and generally on account of widespread concern that the religious life of collegiate communities might be insufficiently rigorous, many collegiate foundations in the 12th century adopted the Augustinian rule, and become fully monastic, as for example at Dorchester Abbey and Christchurch Priory. Because each prebend or portion provided a discrete source of income
