The Lecompton Constitution was adopted by a Convention convened by the official pro-slavery government on November 7, 1857. The constitution would have allowed slavery in Kansas as drafted, but the slavery provision was put to a vote. After a series of votes on the provision and the constitution were boycotted alternatively by pro-slavery settlers and Free-State settlers, the Lecompton Constitution was eventually presented to the U.S. Congress for approval. In the end, because it was never clear if the constitution represented the will of the people, it was rejected.
