From the very beginning, Delaware’s prime location has been a critical factor in the growth of its agricultural industry. Today, agriculture is one of the most successful sectors of the U.S. economy in terms of productivity growth, and a driving force behind Delaware’s economy. Farming is still a family business in Delaware: About 90 percent of farms are either sole or family proprietorships or family-owned corporations. Just under 40 percent of the state’s land is devoted to agricultural production, making it the predominant land use. Here are some highlights of our farming past.

The process of milling had not changed for centuries until Evans made major improvements in a mill on Red Clay Creek in northern Delaware.

  • 1750s

    During this time period, several Quaker families (the Tatnalls, Canbys, Shipleys, Leas, Mortons, and Pooles) had founded Delaware's grain milling industry on the Brandywine River, creating demand for grain shipped by farms up the Delaware River or hauled overland by Conestoga wagon.
