Annexation of Land and spread of slavery. The Mexican-American War (1846) brought with it new lands, giving rise to significant constitutional questions regarding the expansion of slavery into new territories. E.g., in United States v. Ritchie, the US Supreme Court determined the fate of land claims in newly acquired territories after the annexation of California, framing federal courts' determining property rights during westward expansion.
Slavery in the Territories. During their 1858 Illinois Senate campaign, Abraham Lincoln and Stephen A. Douglas debated whether slavery could expand into the federal territories. The debates exposed the conflict among popular sovereignty, Dred Scott, and the constitutional status of slavery, foreshadowing the coming national crisis.
