In the American Revolution, committees of correspondence, committees of inspection (also known as committees of observation), and committees of safety were different local committees of Patriots that became a shadow government; they took control of the Thirteen Colonies away from royal officials, who became increasingly helpless. In Massachusetts, as affairs drew toward a crisis, it became usual for towns to appoint three committees: of correspondence, of inspection, and of safety. The first was to keep the community informed of dangers either legislative or executive, and concert measures of public good; the second to watch for violations of , or attempts of loyalists to evade them; the third to act as general executive while the legal authority was in abeyance. In February 1776 these were regularly legalized by the Massachusetts General Court but consolidated into one called the "Committee of Correspondence, Inspection, and Safety" to be elected annually by the towns. Committees of correspondence Committees of correspondence were public functionaries of a type first appearing in England, created by the parliamentary party of the 17th century in their struggles with the Stuarts. In 1763, when the English government attempted to enforce the trade and navigation acts on the American colonies after the Peace of Paris, the colonial leaders advised the merchants to hold meetings and appoint committees to memorialize the legislature and correspond with each other to forward a union of interests. This was done in Massachusetts, Rhode Island, and New York 1763–64. On 21 November 1772 a town meeting at Faneuil Hall, Boston, appointed a correspondence committee of 21 to communicate with other Massachusetts towns concerning infringements of popular rights. Until late in 1774 (see Committees of Safety) it remained the real executive of the town and largely of the province. The Boston committee, by legal town-meeting, was made the executive of Boston. Under its direction the tea was thrown into the harbor, and the Tea Act of 1773 roused the remaining colonies: Georgia in September, Maryland and Delaware in October, North Carolina in December, New York and New Jersey in February, chose legislative committees of correspondence; and new municipalities joined the movement — several in New Hampshire and Rhode Island and the city of New York. After the Boston Port Bill came into effect the Boston committee invited those of eight other towns to meet in Faneuil Hall, and the meeting sent circulars to the other colonies recommending suspension
