The city was also ranked number one for innovation, both globally and in North America, for a variety of reasons. Boston has been experiencing gentrification, and has one of the highest costs of living in the United States, though it remains high on world livability rankings.
History
Boston was founded on September 17, 1630, by Puritan colonists from England. The Puritans of the Massachusetts Bay Colony are sometimes confused with the Pilgrims, who founded Plymouth Colony ten years earlier in what is today Bristol County, Plymouth County, and Barnstable County, Massachusetts. The two groups, which differed in religious practice, are historically distinct. The separate colonies were not united until the formation of the Province of Massachusetts Bay in 1691.
