Because the state of New York continued to assert that Vermont was a part of New York, Vermont could not be admitted to the Union under Article IV, Section3 of the Constitution until the legislature of New York consented. On March 6, 1790, the legislature made its consent contingent upon a negotiated agreement on the precise boundary between the two states. When commissioners from New York and Vermont met to decide on the boundary, Vermont's negotiators insisted on also settling the property ownership disputes with New Yorkers, rather than leaving that decision to a federal court. The negotiations were successfully concluded in October 1790 with an agreement that Vermont would pay $30,000 to New York to be distributed among New Yorkers who claimed land in Vermont under New York land patents. In January 1791, a convention in Vermont voted 105–4 to petition Congress to become a state in the federal union. Congress acted on February 18, 1791, to admit Vermont to the Union as the 14th state as of March 4, 1791; two weeks earlier on February 4, 1791, Congress had decided to admit Kentucky as the 15th state as of June 1, 1792. Vermont became the first state to enter the Union after the original 13 states. The revised constitution of 1786, which established a greater separation of powers, continued in effect until 1793, two years after Vermont's admission to the Union.
