Connecticut was one of the original 13 colonies and played a key role in early American history. Originally inhabited by the Pequot, Mohegan, and other Indigenous peoples, the area saw English settlement in the 1630s. The Fundamental Orders of 1639 are sometimes called the first written constitution in the New World. Connecticut was a leader in the Revolutionary War, providing supplies, troops, and naval strength. During the 19th century, it became a center of manufacturing, producing textiles, clocks, and firearms. In the 20th century, Connecticut grew into a hub for insurance, finance, and defense. Its history reflects a blend of colonial heritage, industrial growth, and modern innovation.
