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.
