Was the purpose of the committee of corespondence to write to people in Britain?

No, the primary purpose of the Committees of Correspondence was to facilitate communication among the American colonies regarding issues related to British rule and colonial governance. They were established to coordinate resistance against British policies and to share information about actions taken by the colonies in response to those policies. While they did discuss British actions, their focus was on fostering unity and collaboration among the colonies rather than direct correspondence with Britain.
