The 1662 Book of Common Prayer was legally enforced as the liturgy of the Church of England, precipitating the Great Ejection of Dissenter ministers from their benefices.

The 1662 Book of Common Prayer is an authorised liturgical book of the Church of England and other Anglican bodies around the world. In continuous print and regular use for over 360 years, the 1662 prayer book is the basis for numerous other editions of the Book of Common Prayer and other liturgical texts. Noted for both its devotional and literary quality, the 1662 prayer book has influenced the English language, with its use alongside the King James Version of the Bible contributing to an increase in literacy from the 16th to the 20th century.

The Act of Uniformity 1662 is an act of the Parliament of England. It prescribed the form of public prayers, administration of sacraments, and other rites of the Established Church of England, according to the rites and ceremonies prescribed in the 1662 Book of Common Prayer. Adherence to this was required in order to hold any office in government or the church, although the new version of the Book of Common Prayer prescribed by the Act was so new that most people had never even seen a copy. The Act also required that the Book of Common Prayer "be truly and exactly Translated into the British or Welsh Tongue". It also explicitly required episcopal ordination for all ministers, i.e. deacons, priests and bishops, which had to be reintroduced since the Puritans had abolished many features of the Church during the Civil War. The act did not explicitly encompass the Isle of Man.

The Church of England is the established Christian church in England and the Crown Dependencies. It was the initial church of the Anglican tradition. The Church traces its history to the Christian hierarchy recorded as existing in the Roman province of Britain by the 3rd century and to the 6th-century Gregorian mission to Kent led by Augustine of Canterbury. Its members are called Anglicans.
