The Puritans affected America a lot and left a great big legacy behind them. One of these things they left behind were religion. There were Puritan missionaries trying to convert natives to the religion of Christianity. They also brought over things from Europe. Like tools and weapons for example. The Puritans believed in working hard and getting rewarded for it. They certainly changed America in a huge way. That is how I think the Puritans left a legacy behind in America.
By the final years of the seventeenth century, the influence of Puritanism in New England was fading. The religion would never completely lost its distinctively Puritan character, but by 1700, Puritanism's hold over the social, religious, and political life of New England as increasingly challenged by other ideas and values.
