Antigua and Barbuda, a two-island nation whose larger island Antigua was continuously under English and then British control from 1632 until independence, carries one of the longest unbroken Anglican traditions in the Caribbean: the Anglican Church of the Province of the West Indies remains the largest single denomination, though it now sits alongside a broader and roughly comparable body of Protestant churches, Moravian, Methodist, Pentecostal and Seventh-day Adventist chief among them, whose combined membership exceeds Anglicanism's alone.
A significant Roman Catholic minority and small Rastafarian, Baha'i, Hindu and Muslim communities complete the picture on islands whose sugar plantation economy, like much of the eastern Caribbean, was built on enslaved African labor whose descendants make up the great majority of the population today. Barbuda, the smaller and far less populous of the two islands, was long treated under a communal land ownership system distinct from Antigua's, a difference in local governance that has occasionally strained the two islands' political relationship even as their churches operate as a single ecclesiastical body.
