From the Kansas Historical Society:
Unrest was a fact of life in Kansas Territory. Elections fraud was common. The site of the capital was changed several times. At one point, two governments operated in Kansas. As a result of events like these, the political rivalry in the territory of Kansas was intense. It resulted, in part, in the convening of four constitutional conventions (Topeka, 1855; Lecompton, 1857; Leavenworth, 1858; and Wyandotte, 1859), each drafting a constitution under which the delegates hoped the territory would be admitted to the Union.
The first attempt to write a constitution emerged as a movement—the Topeka movement. Delegates assembled at Topeka on October 23, 1855, to draft a constitution. The document was approved on December 15 by a vote of 1,731 to 46. The proslavery—"Law and Order"—party did not participate in the voting on the document. The Topeka Constitution prohibited slavery but excluded free blacks from the state. It also limited suffrage to white males and "every civilized male Indian who has adopted the habits of the white man." Although Congress rejected this constitution and the request for admission to the Union, the "Topeka Movement" remained active for another three years.
