The Middle Colonies document provides information on the four colonies that made up the Middle Colonies region - New York, New Jersey, Pennsylvania, and Delaware. It summarizes that the Middle Colonies were settled on rich river lands, making farming and mining important economic activities. It also notes that the English created New York and New Jersey from former Dutch territory, and that William Penn established Pennsylvania to provide refuge for Quakers. The economies of the Middle Colonies relied on both subsistence and commercial farming of crops like wheat, oats, and corn, as well as trade with other colonies facilitated by the region's rivers and harbors.
