The Episcopal Church is part of the worldwide Anglican Communion. It is divided into nine provinces and has dioceses in the U.S., Taiwan, Micronesia, the Caribbean, Central and South America, as well as the Convocation of Episcopal Churches in Europe and the Navajoland Area Mission. The Episcopal Church describes itself as being 'Protestant, yet Catholic'. In 2010, it had 2,125,012 baptized members, of which 1,951,907 were in the U.S., making it the nation's 14th largest denomination. The church is also known as the Protestant Episcopal Church in the United States of America (ECUSA).
The church was organized after the American Revolution, when it separated from the Church of England whose clergy are required to swear allegiance to the British monarch as Supreme Governor of the Church of England, and became the first Anglican Province outside the British Isles.
