What these people have in common is that they were all concerned with religious liberty. George Calvert was an Englishman who arrived to what is now modern day Canada (Newfoundland) and the United States (Maryland) in hopes of establishing a colony where Catholicism would prosper as it could not in his native land. Roger Williams was a Protestant theologian who was a proponent of religious liberty and of the separation of church and state. William Penn was also a proponent of religious freedom. Anne Hutchinson viewed Puritanism (a branch of Protestantism) in a more open view than her conservative counterparts.
