What were the committees of correspondence and how did they the patriot cause?

The Committees of Correspondence were the American colonies’ means for maintaining communication lines in the years before the Revolutionary War. In 1764, Boston formed the earliest Committee of Correspondence to encourage opposition to Britain’s stiffening of customs enforcement and prohibition of American paper money.
