The First State
On December 7, 1787, Delaware became the first state to ratify the U.S. Constitution.

Delaware is the first state to ratify the U.S. Constitution (December 7, 1787) and the second smallest by area, yet it plays an outsized role in the American economy: more than 1.9 million business entities are incorporated here, including roughly two thirds of Fortune 500 companies, thanks to the Court of Chancery and its business-friendly corporate law. Its 1.05 million residents are concentrated in New Castle County around Wilmington, while Kent and Sussex counties combine farming, poultry production and the fast-growing beach economy of Rehoboth and Lewes. Delaware has no state sales tax, one of the lowest effective property tax rates in the country and a large finance, chemical and pharmaceutical base rooted in the DuPont legacy.
