About Delaware
Delaware is the second-smallest state in the United States, located on the mid-Atlantic coast, yet it wields outsized influence as a corporate and financial hub. Its capital is Dover, while Wilmington is the largest city. Nicknamed the First State, it was the first to ratify the US Constitution in 1787.
Delaware occupies part of the flat, low-lying Delmarva Peninsula, with sandy Atlantic beaches, tidal marshes and gentle farmland. The Delaware River and Bay form its eastern boundary. The climate is humid subtropical to temperate.
Delaware blends mid-Atlantic and Northeastern influences, with popular beach towns such as Rehoboth, a strong colonial heritage, and a business-friendly identity. Its small size fosters a close-knit community feel.
Settled by the Dutch, Swedes and English, Delaware was one of the original Thirteen Colonies and earned lasting fame as the first state to ratify the Constitution on December 7, 1787. Its modern prominence comes from corporate law that makes it the legal home of most large US companies.
