Established Church

An established church is a religious body formally recognized by the state as the official or state religion, typically receiving legal privileges, sometimes public funding, and a formal constitutional role that other religious bodies in the same country do not share. The Church of England remains established, with the reigning monarch as its Supreme Governor and senior bishops sitting by right in the House of Lords, alongside several established or semi established Lutheran national churches in the Nordic countries, though the degree of formal state control has generally loosened over the twentieth and twenty first centuries even where establishment itself continues.

Islamic states commonly designate Islam, or a specific school of Islamic jurisprudence, as the state religion in their constitutions, with varying degrees of practical legal consequence for governance and law. Establishment is not confined to Christianity or Islam: several countries formally recognize a state Buddhism, including Cambodia, Sri Lanka and, more contested and layered with other institutions, Thailand, illustrating that establishment as a legal category recurs across traditions rather than being a peculiarly Christian arrangement.

Establishment today rarely means what it did in earlier centuries, when an established church could enjoy a formal monopoly on public worship and civic office was restricted to its members, since most contemporary states with an established church also constitutionally guarantee religious freedom for other faiths and for non belief, producing a hybrid arrangement, formal state recognition of one religion alongside legal protection for all others, that differs sharply from full theocracy on one side and strict separation of church and state on the other.

Disestablishment, the formal removal of a church's established status, has happened repeatedly across the modern period, including the Church of Ireland in 1871, the Church in Wales in 1920, and Sweden's Lutheran church in 2000, generally reflecting a country's judgment that formal establishment no longer matched its religious diversity or its citizens' expectations of state neutrality. The practical consequences of establishment vary enormously by country, from largely ceremonial roles, a monarch's coronation performed by an archbishop, to substantive legal privileges affecting funding, education and family law, so establishment is best treated as a spectrum of arrangements rather than a single fixed constitutional status.
