How many states had religious establishment?

As of now, the United States had several states with established religions in its early history, particularly in the colonial period. By the time the Constitution was ratified in 1788, some states, like Massachusetts and Connecticut, maintained official state religions. However, the First Amendment's Establishment Clause effectively prohibited the federal government from establishing a religion, leading to the eventual disestablishment of state-sponsored religions. By the 1830s, most states had moved away from religious establishment.
