The Southern planter aristocracy was the primary driver in the political crisis. Calhoun and the South Carolina planters tried to convince other states to secede whenever a crisis sprung up, since they needed a place to dump their excess slave population, and the ban on the international slave trade would make that impossible if SC was alone. What made John Brown a southern bogeyman was that he embodied the southern nightmare scenario: a Haiti-style slave revolt/race war. Just as SC needed other states to offload their excess slaves, the South as a whole needed new land to spread their growing slave population, especially as the soil back east was being depleted by King Cotton. Slavery, cotton, and territorial expansion were the three pillars of the southern economy. The other driving force behind the proslavery movement was the assumption that free states would always vote against the interests of slave states.

The Knights of the Golden Circle was a southern group advocating the annexation of former Spanish colonies (Cuba, Central America) to create more slave states and more plantations. Setting them aside, the Federal government had to dissuade southerners from joining privately funded filibustering expeditions to conquer Latin American countries. Leaving aside the speculation, the rationale for taking Texas and the Mexican Cession was southern settlement. That the land was unsuited for plantation farming, or that the locals didn’t want slavery imposed where it had been abolished, and the white settlers (mostly southerners, including California’s governor and all of its Congressmen) agreed with them, was a nasty shock.
