Answer:
The Maryland Toleration Act, also known as the "Act on Religion", was a law that allowed tolerance towards Christians who recognized the Trinity dogma as true.
Approved on September 21, 1649 by the assembly of the Maryland province, it was the second law dealing with the issue of religious tolerance between the British colonies of North America and the first in the world against opinion discrimination. The first law concerning religious matters among the North American colonies was approved in Rhode Island in 1636.
The Calvert family, which founded Maryland primarily as a refuge for English Catholics, was aimed at creating a body of laws that protected the Catholic settlers or at least all those who did not conform to Anglicanism, then dominant in the Kingdom of England and in its colonies.
