In 1829, North Carolina’s Supreme Court made their decision on Mann v. State, a case which revealed the realities of slavery in early 1800s America and the ways in which our legal system upheld its institution. Mann v. State had a significant impact on the United States as it further stripped away any protection that enslaved people had under the law. To understand the historical impact of Mann v. State, we need to look at both the court’s ruling and the broader national occurrences going on in the same time period.

The case itself was in regard to John Mann, who had hired an enslaved woman named Lydia, to do work on his plantation. Mann told Lydia to do something, which she resisted, leading Mann to attempt to punish her. In order to avoid this, Lydia attempted to run away and escape the abuse, leading Mann to shoot her in the back. She was wounded, but survived, and Mann was taken to court for injuring a slave that wasn’t his.
A lower level court in North Carolina convicted John Mann of battery, however he didn’t like this ruling and the case was taken to the Supreme Court. Supreme Court Justice Thomas Ruffin overturned this ruling, as “power of the master must be absolute.” Justice Ruffin admitted to moral and personal discomfort over this case and his ruling, but he claimed that the law shouldn’t undermine the authority of masters over enslaved people. This ruling further set the precedent that enslaved individuals had no protection, even under the law, to those who inflicted violence upon them and held authority over them.

A decade before Mann v. State, the Missouri Compromise had revealed how divisive slavery was becoming at a national level. The compromise maintained the balance of free and slave states, but also highlighted the fact that the country was becoming more divided. Decisions like Mann v. State reflected the South’s determination to defend slavery against any moral, political, or legal encroachments to protect their economic livelihood.
Although abolitionism was still in its early stages in the late 1820s, some voices were beginning to call the practice of slavery into question. David Walker, a free black man from North Carolina, published Appeal to the Colored Citizens of the World, which called for resistance against slavery. His stance and appeal to a group of the public was not taken well by many Southerners and plantation owners, who feared uprising, opposition, and the loss of their labor force. The legal ruling in Mann v. State can be seen as a part of the South’s attempt to defend themselves against the growing opposition to slavery.

slaves couldn’t be punished for violence against enslaved people.
By understanding Mann v. State, we can observe how courts were active participants in preserving slavery in the south and how this legal history still shapes conversations in our modern day and age.
