Connecticut History

The area of Connecticut was part of the original territory of the United States. It was chartered as a colony in 1662. In 1786, it ceded area to the United States’ government that became part of the Northwest Territory in 1787. Connecticut ratified the U.S. Constitution on January 9, 1788; it was the fifth of the original 13 states to join the Union. Its boundary was generally the same as the present state (excluding the Connecticut Western Reserve), although the boundary between Connecticut and Massachusetts was changed slightly in 1804.

Census data for Connecticut are available beginning with the 1790 census.

Other Information Of General Geographic Interest

The irregularity of the boundary in southwestern Connecticut where it abuts New York State, called the Connecticut Panhandle, is the result of territorial disputes in the late 17th century. New York gave up its claim to this area in exchange for an equivalent area extending northwards from Ridgefield, Connecticut to the Massachusetts border and an undisputed claim to Rye, New York. The two British colonies negotiated an agreement in November 1683 establishing the New York-Connecticut border as 20 miles east of the Hudson River, north to Massachusetts.
