There were several attempts to resolve this question, as the Western territories were coming up for statehood. The Missouri Compromise related to the territories acquired from France in the Louisiana Purchase. After the Mexican war, they had to replace this with a new compromise to accommodate the new territories acquired from Mexico. When this proved unpopular, they tried organising a local vote on the issue. That just led to violence.

They feared the new acquired territories would undermine the delicate balance between slave and non-slave states. They tried to ban slavery on the new territories by introducing the Wilmot Proviso (1846). However, many of these territories were already pro-slavery, including New Mexico and Texas. This unresolved issue was one of the main reasons of the American Civil War (1861-1865).
