"free state" in ks, as enshrined in the 1855 Topeka constitution which was approved by kansas voters but ultimately rejected by the federal government, banned slavery but went a step further and explicitly excluded free blacks from settling in the territory, preserving an "all white" society. keeping kansas free FROM blacks, not free FOR blacks, was the objective of the "free state" movement and the goal of their proposed constitution and application for statehood in 1855.

while the Topeka constitution ultimately failed, the "free state" party continued pushing for statehood and drafting a workable constitution that was slightly less overtly racist. eventually they got to a version that would pass federal approval, but the more prominent leaders of the exclusionist wing of the party went on to hold most of the power in the state, with the main proponent of exclusionism, James Lane, going on to become one of the state's first senators.
