The Wyandotte Constitution is the constitution of the U.S state of Kansas . The present Constitution of the State of Kansas was originally known as the Wyandotte Constitution to distinguish it from three proposed constitutions that preceded it . The Wyandotte Constitution was drawn up at Wyandotte ( now part of Kansas City ) in July 1859 , and was the fourth constitution voted on by the people of Kansas Territory , as the battle between proslavery and antislavery forces during the Bleeding Kansas era spread to the debate over the terms of the new state 's charter .
