Maryland was specifically established with the intention of granting religious freedom to Catholics. The first Mass in the colonies was celebrated there on March 25, 1634. Despite attempts by Puritans to persecute them, Catholics survived in Maryland.
Cecil Calvert intended for Maryland to be a refuge where English Roman Catholics could live without religious persecution. He established this colony in 1634. Cecil Calvert's title was Second Lord Baltimore.
