America’s early settlers came from a variety of religious backgrounds: Puritans predominated in New England; Anglicans predominated in the South; Quakers and Lutherans flocked especially to Pennsylvania; Roman Catholics settled mostly in Maryland; Presbyterians were most numerous in the middle colonies; and there were Jewish congregations in five cities.
During colonial times, the Church of England was established by law in all of the southern colonies, while localized Puritan (or “Congregationalist”) establishments held sway in most New England states. In those colonies, clergy were appointed and disciplined by colonial authorities and colonists were required to pay religious taxes and (often) to attend church services. Dissenters were often punished for preaching without a license or refusing to pay taxes to a church they disagreed with. Delaware, New Jersey, Pennsylvania, Rhode Island, and much of New York had no established church.
After Independence, there was widespread agreement that there should be no nationally established church. The Establishment Clause of the First Amendment, principally authored by James Madison, reflects this consensus. The language of the Establishment Clause itself applies only to the federal government (“Congress shall pass no law respecting an establishment of religion”). All states disestablished religion by 1833, and in the 1940s the Supreme Court held that disestablishment applies to state governments through the Fourteenth Amendment.
