What was the purpose of the Committee's of Correspondence?

Answer 1

The Committees of Correspondence were set up by Patriot leaders in the American Colonies to exchange information, establish plans for collective action by the colonies, and to coordinate efforts among the colonies. They undermined British and Loyalist efforts, and eventually organized to the point of taking concerted actions, which ranged from publishing the names of uncooperative merchants (those who violated boycotts) to establishing networks of spies in British commands.

Answer 2

In an era before modern communications, news was generally disseminated in hand-written letters that were carried aboard ships or by couriers on horseback. Special committees of correspondence were formed by the colonial assemblies and various lesser arms of local government. The committees were responsible for taking the sense of their parent body on a particular issue, committing it to a written form and then dispatching that view to other similar groups.
