Which colony is known for its complete religious freedom established by Roger Williams?

Rhode Island is known for its complete religious freedom, which was established by Roger Williams. Williams, who was a Puritan minister, advocated for the separation of church and state and believed that individuals should have the freedom to practice their own religion without interference.

After facing opposition in Massachusetts due to his beliefs, Williams founded Rhode Island in 1636 as a refuge for those seeking religious liberty. The colony became a haven for various religious groups, including Quakers, Jews, and Baptists, who faced persecution elsewhere. This commitment to religious tolerance was a foundational principle of Rhode Island and differentiated it from many other colonies at the time, which often enforced strict religious conformity.
