Committees of Correspondence, patriot groups formed in the American colonies before the Revolution. The purpose of the committees was to exchange information, spread propaganda, and coordinate efforts of the various colonies in resisting British taxes and restrictions. They did much to win public support for the movement leading to the Revolution.
The first committee, organized by Samuel Adams in Massachusetts in 1772, was local in character. The following year the Virginia legislature organized a committee representing the entire colony. Eleven other colonies formed similar groups within a year. A third type was organized on the county level.
