What did antislavery people do when pro slavery people formed a government Kansas's?

When pro-slavery supporters formed a government in Kansas, antislavery activists responded by establishing their own rival government, known as the Free State government. This led to significant conflict, often referred to as "Bleeding Kansas," where both sides engaged in violent confrontations over the issue of slavery. Antislavery settlers also worked to promote their cause through political activism, rallies, and forming alliances with like-minded groups. Ultimately, this struggle highlighted the deep national divisions over slavery that would culminate in the Civil War.
