The Fundamental Orders were adopted by the Connecticut Colony council on January 24 [O.S. January 14] 1639. The fundamental orders describe the government set up by the Connecticut River towns, setting its structure and powers. They wanted the government to have access to the open ocean for trading.

The Orders have the features of a written constitution and are considered by some authors to be the first written Constitution in the Western tradition. Thus, Connecticut earned its nickname of The Constitution State. The document is notable as it assigns supreme authority in the colony to the elected general court, omitting any reference to the authority of the British Crown or other external authority. In 1662, the colony petitioned the king for a royal charter, which substantially secured the colony's right to self-govern following the same form of government established by the Fundamental Orders.
