In the southern colonies which were Virginia and the Carolinas, the colonies used a plantation model. The other colonies, which included New England, Pennsylvania, New York, New Jersey, and Delaware, also called the Middle Colonies, operated under a family farm model. Both attracted very large numbers of settlers during their first century. Like the French, the English hoped to find gold and silver in their American colonies, as did the Spanish. Which ultimately didn't have much success. As for the economy, the English have had great success in the tobacco sector. By 1617, settlers were producing 70,000 books per year. By the end of the American Revolution, production reached 100,000,000 books per year. This represents nine months of work each year to cultivate. Plantation owners relied on the labor of African slaves to do the work. Settlement in New England differed from the Virginia pattern. Its main focus was family farming and urban life. The Puritans who settled in Massachusetts built their settlements around the center of the city. Daily life revolved around religion and family. Boston was the colony's first settlement. The Native American population helped the English settlers stay alive; they supplied the new arrivals and taught them to survive. However, the English did not treat the Native Americans well in return. Sometimes the English shot the Native Americans without provocation. The Church of England is a Christian church. After 1534, people who still wanted to become Catholics were persecuted by the English government because the Church of England was the established church. Lord Baltimore decided to found a colony in America where Roman Catholics could worship.
