What colonies allowed religious toleration?

There were 3 main colonies that were established for the sole purpose of religious freedom.

One was in Maryland, established by George Calvert. Meant for Puritans, it was establish due to their dislike of Roman Catholics.

In Pennsylvania, another one was established by William Penn for Quakers.

Finally, Rodger Williams in settled in RI after leaving Salem, MA. This became a religious sanctuary for all religions.

This is assuming the questions context; but I hope this was able to answer your question, or minimally help you out!
