In the 19th century, the District of Delaware was known for its production of gunpowder, and several gunpowder mills were established in the region. One of the most famous mills was the Hagley Powder Mills, which were founded by the DuPont family in the early 1800s. The mills were a major supplier of gunpowder to the U.S. military during the Civil War.
