About “Leavenworth Constitution”
The Leavenworth Constitution was one of four Kansas state constitutions proposed during the era of Bleeding Kansas in 1858, and it was never adopted. Drafted by a convention of Free-Staters, it was the most progressive of the four proposals, featuring a Bill of Rights referring to "all men," a ban on slavery, and a basic framework for women's rights.
