Connecticut History and Research Overview

By Family Tree Editors Premium


Prior to European settlement, Native American tribes including the Mohegan, Nipmuc, and Pequot resided in the area that would become Connecticut. Connecticut towns founded in the early 17th century by European settlers include Windsor (1633), Wethersfield (1634), and Saybrook (1635). Congregational minister Reverend Thomas Hooker and his followers from Massachusetts, seeking political and religious freedoms, established Hartford in 1636 and became part of Connecticut Colony. Hooker’s beliefs formed the foundation of The Fundamental Orders of Connecticut (1639), the first written constitution in the colonies that codified laws and allowed residents to elect public officials.

In 1662, King Charles granted Connecticut Colony a new charter that gave settlers land and control over their governance. Connecticut Colony merged with New Haven Colony, which included only six towns along Long Island Sound, in 1665. Colonial conflicts, such as the Pequot War of 1636 and King Philip’s War of 1675-76, erupted between native populations and Europeans.


During the American Revolution, British troops captured Fort Griswold in New London and raided towns along the coastline. After the war, Connecticut delegates objected to the strong central government proposed for the new country. They lobbied for The Connecticut Compromise, the two-house legislature with equal representation in the Senate and population-based leadership in the House — the system still used today. Connecticut became the fifth state after ratifying the Constitution in 1788.

In 1818, a new state constitution allowed most men age 21 and over to vote and disestablished the Congregational Church. Connecticut outlawed buying and selling slaves in the state in 1784, completely abolishing slavery in 1848.

Until the early 18th century, most of the population farmed the rocky soil, but in the 1720s, they began migrating to the cities for work in mills, mines, and small factories. “Yankee Peddlers” traded the manufactured goods to other areas of the country. During the 19th century, immigrants from Italy, Germany, Canada, Ireland, and Poland sought employment in Connecticut’s growing industrial economy.

Transportation innovations improved the exportation of goods via the Farmington Canal (1828-1847) and rail lines between Providence and Stonington (1837) and between New Haven and New York City (1848), just two of the many operating in the state in the 19th century. Several towns along the southern coast built ships and participated in the whaling industry. Many early insurance companies formed in Hartford to insure goods being sent overseas.

Nearly 60,000 Connecticut soldiers fought in the Civil War, and its factories produced uniforms, weapons and ships. Connecticut men and women participated in all the major military conflicts of the 20th century and manufactured many of the weapons.
