Final answer:
Maryland was founded in 1633 as a safe haven for Roman Catholics, providing religious freedom through the Maryland Toleration Act of 1649 for all Christians.
Step-by-step explanation:
The colony that was founded as a safe haven for Roman Catholics was Maryland. It was established in 1633 by George Calvert, Lord Baltimore, with the intention of providing a refuge for Catholics who were facing persecution in Protestant England.
The Maryland Toleration Act of 1649 showcased Maryland's liberal religious policies by guaranteeing religious freedom for all Christians, although it still maintained a death penalty for anyone who denied the divine nature of Christ. This made Maryland an attractive destination not only for Catholics but for other Christian denominations seeking freedom from religious persecution.
