Anti-Nebraska Movement

The Anti-Nebraska Movement was a political effort in the mid-1800s opposing the Kansas-Nebraska Act of 1854. This act allowed settlers in those territories to decide for themselves whether to permit slavery, which alarmed many Northerners who wanted to prevent the spread of slavery. The movement unified various groups who opposed the expansion of slavery into new territories, leading to the formation of the Republican Party. It signified a shift in national politics, emphasizing moral and economic opposition to slavery and helping to set the stage for the Civil War.
