What resolution was reached after the "bleeding kansas" affair?

Kansas was admitted to the Union as a free state in January 1861, but partisan violence continued along the Kansas–Missouri border for most of the war. The episode is commemorated with numerous memorials and historic sites.

Explanation:

Bleeding Kansas was demonstrative of the gravity of the era's most pressing social issues, from the matter of slavery to states' rights to the class conflicts emerging on the American frontier. Its severity made national headlines which suggested to the American people that the sectional disputes were unlikely to reach compromise without bloodshed, and it therefore directly presaged the American Civil War.[3]
