The Demon of Unrest Summary The Political and Social Fabric of Secession

Larson argues that slavery was closely linked to secession. The South’s declarations of secession demonstrated that slavery was the central issue. For example, South Carolina’s declaration accused the federal government of violating the Constitution by not returning escaped slaves to their owners and accused the North of inciting slaves to rebel. Meanwhile, Mississippi’s declaration stated that the state’s stance was "completely connected to slavery—the world's primary economic interest." This declaration claimed that Northern hostility to slavery threatened commerce and civilization.

(Shortform note: Some people argue that secession was not about slavery.

To reduce the chance of the Carolina guard steamers detecting them, he arranged for his soldiers to relocate at dusk. He maintained secrecy about his intentions, and the move was a surprise to many, including his second-in-command.

(Shortform note: The standoff at the fort took place within the context of the Antebellum Army, which was the United States Army during the period before the Civil War. The Antebellum Army was a small, professional force tasked with defending the nation’s borders, maintaining order on the frontier, and protecting federal property. Army regulations and customs of the time gave post commanders significant autonomy, especially in isolated or emergency situations. Commanders were expected to take whatever measures they deemed...
