Colonies such as Massachusetts, Pennsylvania and Maryland were settled primarily by people seeking religious freedom. Pilgrim Separatists desired a break from the Church of England, and arrived in Massachusetts aboard the Mayflower in 1620. Later, a different religious sect, the Puritans, arrived in Massachusetts fleeing persecution in England. Unlike the Separatists, the Puritans did not want to break from the Church of England; they wanted to "purify" it. This was met with opposition -- including violence -- and by 1630 nearly 20,000 Puritans fled to Massachusetts. Colonies such as Maryland were founded as a refuge for other persecuted religious groups. English persecution -- like a ban on a Catholic priest officiating a marriage of two Catholics -- prompted many to come to Maryland. Lord Baltimore founded Maryland as a Catholic refuge in 1632.
