The New York Provincial Congress (1775–1777) was a revolutionary provisional government formed by colonists in 1775, during the American Revolution, as a pro-American alternative to the more conservative New York General Assembly, and as a replacement for the Committee of One Hundred. The Fourth Provincial Congress, resolving itself as the Convention of Representatives of the State of New York, adopted the first Constitution of the State of New York on April 20, 1777. Background Committees of correspondence The Committee of Fifty-one was a committee of correspondence in the City and County of New York that first met on May 16, 1774. On May 30, the Committee formed a subcommittee to write a letter to the supervisors of the counties of New York to extort them to also form similar committees of correspondence, which letter was adopted on a meeting of the Committee on May 31. In response to the letters from Boston, on July 4, 1774 resolutions were approved to appoint five delegates, Isaac Low, John Alsop, James Duane, Philip Livingston, and John Jay, to the "Congress of Deputies from the Colonies" (the First Continental Congress), and request that the other counties also send delegates. Three counties (Westchester, Duchess, and Albany) acquiesced to the five delegates, while three counties (Kings, Suffolk, and Orange) sent delegates of their own. The First Continental Congress met from September 5 to October 26, 1774. New York General Assembly In January and February 1775, the New York General Assembly voted down successive resolutions approving the proceedings of the First Continental Congress and refused to send delegates to the Second Continental Congress. New York was the only colonial assembly which did not approve the proceeds of the First Continental Congress. Opposition to the Congress revolved around the opinion that the provincial houses of assembly were the proper agencies to solicit redress for grievances. In March, the Assembly broke with the rest of the colonies and wrote a petition to London, but London rejected the petition because it contained claims about a lack of authority of the "parent state" to tax colonists, "which made it impossible" to accept. The Assembly last met on April 3, 1775. Provincial Convention (Second Continental Congress) A Provincial Convention assembled in New York City on April 20, 1775 where delegates were elected to the Second Continental Congress. On March 15, 1775 the Committee of Sixty had issued a call to the counties
