A parish is a territorial division within a Christian diocese, under the pastoral care of a priest, often called a parish priest. The priest operates from a parish church and may be assisted by curates. Historically, parishes often corresponded geographically with manors. The connection between a parish and its church remains central.
The Church in Wales was disestablished in 1920, retaining the parish system.
In 1929, parishes ceased to be units of civil government in Scotland, becoming purely ecclesiastical entities.
Communities were established as civil administration areas in Wales in 1974, replacing parishes in that role.
In July 2007, the motu proprio Summorum Pontificum was issued, allowing for the establishment of personal parishes for Catholics attached to the pre-Vatican II liturgy.
In 2010, the Church in Wales commissioned a review into its organization, led by Rt Rev Richard Harries, Prof Charles Handy, and Prof Patricia Peattie.
The "Church in Wales Review" report, proposing the reorganization of parishes into larger Ministry Areas, was published in July 2012.
The final Ministry Areas, as recommended by the "Church in Wales Review", were instituted in 2022.
