In which region did colonial founders believe most strongly in freedom of religion?

In the early years of what later became the United States, Christian religious groups played an influential role in each of the British colonies, and most attempted to enforce strict religious observance through both colony governments and local town rules.

Most attempted to enforce strict religious observance. Laws mandated that everyone attend a house of worship and pay taxes that funded the salaries of ministers. Eight of the thirteen British colonies had official, or “established,” churches, and in those colonies dissenters who sought to practice or proselytize a different version of Christianity or a non-Christian faith were sometimes persecuted.

Although most colonists considered themselves Christians, this did not mean that they lived in a culture of religious unity. Instead, differing Christian groups often believed that their own practices and faiths provided unique values that needed protection against those who disagreed, driving a need for rule and regulation.
