On the ground
- Kansas and Nebraska territories — the 36°30′ line repealed on 30 May 1854 and slavery left to a vote of the settlers; Kansas became a battlefield within two years
- Utah and New Mexico territories — open to slavery by popular sovereignty; Utah legalised servitude in 1852 and New Mexico passed a slave code in 1859; a federal law of 19 June 1862 barred slavery from every territory
