Economy

Delaware’s economy is notable for its business-friendly environment and corporate presence—over a million businesses are incorporated in the state due to its favorable tax laws and specialized Court of Chancery. Finance, insurance, and legal services dominate, especially in Wilmington. The state also has strong chemical and pharmaceutical industries, with DuPont historically headquartered here, and newer growth in biotechnology. Agriculture remains important in rural areas, with poultry, soybeans, and corn as key products. Tourism contributes significantly, centered around Delaware’s Atlantic beaches, historic sites, and tax-free shopping. The Port of Wilmington and nearby transportation networks support trade and logistics.

History

Delaware was originally home to Indigenous peoples including the Lenape and Nanticoke. It was first settled by the Dutch in 1631 and later claimed by the Swedes and English. Delaware was one of the thirteen original colonies and played a critical role in the American Revolution. On December 7, 1787, it became the first state to ratify the U.S. Constitution, earning its nickname “The First State.” Its location made it strategically important during the Civil War, though it remained in the Union despite being a slave state. Over time, Delaware grew into a hub for industry, shipping, and corporate law. Today, it maintains its historic identity while fostering a modern, business-driven economy.
