The map shows the city of Boston in 1814, and we can compare to other maps to see how the city has expanded as the population increases.
Boston was founded in 1630 by English Puritans that arrived in America after being persecuted in Britain due to their religious beliefs. John Winthrop was the leader of the group.
Today, Boston is the capital city of Massachusetts and the largest city in the state. Its actual population is 685, 000 people, although the metropolitan area is connected to other cities.
