It was a radical set of resolves passed by a county convention in Massachusetts in the Fall of 1774 in response to the Coercive Acts. It was essentially written by the head of the convention Joseph Warren. He was eventually killed on Breed's Hill in the Battle of Bunker Hill in the following year. Once the convention had adopted the resolves, Paul Revere rode a copy to the Continental Congress in Philadelphia who endorsed them. They were a direct influence on the Articles of Association and Declaration of Causes which the Continental Congress issued the following month - effectively uniting the colonies under the directorship of the Convention.
The main way in which support for the Suffolk Resolves by the Continental Congress pushed the colonies closer to war is because this inspired people to take up arms and form groups, which eventually turned into militias.
