Important Dates, Events, and Milestones in Delaware

Offers a chronological timeline of important dates,  events, and milestones in Delaware history.

The first of the original 13 states to ratify the federal Constitution, Delaware occupies a small niche in the Boston–Washington, D.C., urban corridor along the Middle Atlantic seaboard. It is the second smallest state in the country and one of the most densely populated.

Delaware was inhabited nearly 10,000 years ago, and a succession of various cultures occupied the area until the first European contact. At that time, the Leni-Lenape (Delaware) Indians occupied northern Delaware, while several tribes, including the Nanticoke and Assateague, inhabited southern Delaware.

The Lenape, culturally organized bands of Native Americans, settle along the Delaware River circa 1400. In 1600, the Minquas (named after the Lenape word for "treacherous") from the Susquehanna River Valley attack their villages. Two groups of Native Americans are present in the Delaware region by the turn of the 16th century: the Lenape and the Nanticoke.
