Between 1860 and 1861, eleven Southern states defied the authority of the U.S. government and seceded from the Union, asserting a doctrine of states' rights. Ironically though, for several years before the war, Wisconsin had been the most thoroughgoing champion of states' rights. Unlike the Southern states, however, Wisconsin had used the doctrine in opposition to, rather than in support of, slavery. States' rights had been the basis of the Wisconsin Supreme Court's decision to nullify the 1850 Fugitive Slave Act after the controversy surrounding the fugitive slave Joshua Glover (see "Abolitionism and Other Social Reforms").
