What was one result of the treatment that Catholics in England often faced during the 1600s? Some Catholics refused to swear loyalty to the king of England.
Some Catholics left England to settle in North America.
Some Catholics founded the colony of Pennsylvania in 1681.
Some Catholics were forced out of the Church of England.

Strangely enough it never affected the English Catholics' patriotic feelings. Persecution of Catholics for purely religious reasons were rare; and although for a period all citizens were officially required to regularly attend Church of England church services the enforcement of this law was a local matter and Catholics were usually left pretty much alone. The distrust of Catholics' loyalty to the British Crown led however to a law that would only be repealed in the 19th century, banning Catholics from holding any local or central administrative office.
