In 1846, a free Black abolitionist named Moses Dickson founded a secret organization known as the Knights of Liberty. The group’s goal was ambitious and dangerous: to organize enslaved and free African Americans across the South and prepare for a large-scale uprising against slavery that could have dealt a devastating blow to the institution of slavery.
For decades, enslaved Africans had resisted in every way imaginable. Some escaped through the Underground Railroad, some poisoned masters, some sabotaged plantations, and others launched outright rebellions. The Haitian Revolution had already shown the world that enslaved Africans could overthrow an entire slave system through violence, and ever since then, the possibility of armed Black revolt haunted white slaveholding societies across the Americas.
It was within that atmosphere that one of the most mysterious Black resistance organizations in American history reportedly emerged.
According to later accounts by abolitionist Moses Dickson, a secret all-Black militant organization known as the Knights of Liberty was founded in St. Louis, Missouri, in 1846 with one objective: to prepare for a massive armed insurrection against slavery in the United States.
If the claims surrounding the organization are accurate, the Knights of Liberty may have represented one of the largest planned slave uprisings in American history.
Dickson was born in Cincinnati, Ohio, in 1824. Unlike millions of Africans living in bondage at the time, he was born free, but growing up free in America did not mean escaping the shadow of slavery. As a young man, Dickson reportedly worked on Mississippi River steamboats, where he traveled through slave states and witnessed slavery up close. He saw enslaved Africans chained, bought, sold, and brutalized throughout the South, experiences that deeply shaped his worldview.
Eventually, he settled in St. Louis, Missouri, a city that occupied a strange position in the American slave system. Missouri was a slave state, but St. Louis also contained free Black communities, anti-slavery activists, and Underground Railroad activity. The city became a crossroads where slavery and resistance existed side by side.
According to Dickson’s later writings, on August 12, 1846, he and eleven other Black men secretly met in St. Louis and founded the Knights of Liberty. The organization was allegedly built around strict secrecy, military discipline, and preparation for war. Members reportedly took secret oaths and organized hidden chapters across slave states and border regions.
Their goal was not merely to help enslaved Africans escape, but was to destroy slavery itself through armed revolt.
Dickson later claimed that the organization recruited both free and enslaved Black people, secretly trained men for combat, and stockpiled weapons while preparing for a future uprising. According to his account, the organization spread across several states and eventually grew into a massive underground network.
One of the most dramatic claims surrounding the Knights of Liberty was that the organization planned to launch a coordinated rebellion centered around Atlanta, Georgia. Dickson claimed the revolt would target transportation systems, seize weapons, and trigger a chain reaction of uprisings throughout the South.
Some of his later statements suggested the organization had tens of thousands of members.
That figure remains heavily disputed today.
Many historians are skeptical because much of what is known about the Knights of Liberty comes from Dickson’s own recollections decades later, and there is limited independent evidence confirming the enormous scale he described. Some historians believe Dickson likely exaggerated certain details, especially the claimed membership numbers. Others argue that the secrecy of the organization itself may explain why so few records survived.
Still, historians generally agree that Dickson was genuinely involved in anti-slavery organizing and Underground Railroad activity, and most do not dismiss the possibility that some form of secret militant network existed around him.
The story also fits within a broader historical reality that is often ignored in mainstream narratives about slavery in the United States.
Black resistance was not always peaceful.
Long before the Civil War, free and enslaved Africans had repeatedly discussed, planned, and sometimes carried out violent resistance against slavery. In 1831, Nat Turner led one of the most famous slave revolts in American history, killings dozens of white people in Virginia before the rebellion was crushed. Earlier still, Denmark Vesey had organized a massive planned uprising in Charleston, South Carolina, though authorities stopped it before it began.
The mere fear of Black rebellion shaped Southern society for generations. Slave patrols, curfews, violent punishments, and strict laws restricting Black movement all existed partly because white slaveholders constantly feared insurrection.
The Knights of Liberty emerged from that same world.
According to Dickson, the planned uprising was eventually abandoned because national events were already pushing the United States toward civil war. By the late 1850s, violence between pro-slavery and anti-slavery factions had intensified dramatically, especially in Kansas, where armed conflict broke out over whether the territory would permit slavery. Dickson reportedly concluded that a nationwide war between North and South was becoming inevitable and that such a war might destroy slavery more effectively than a risky insurrection.
In 1861, the Civil War finally erupted.
For many free and enslaved Africans, the war became the armed struggle against slavery they had anticipated for decades. Thousands eventually joined Union forces, fought Confederate armies, sabotaged plantations, and transformed the conflict into a war against slavery itself. In many ways, the central idea behind the Knights of Liberty, that slavery in the United States would ultimately have to be destroyed through violence, proved correct.
After the Civil War, Moses Dickson remained active in Black civic and fraternal organizations. He later became associated with the International Order of Twelve Knights and Daughters of Tabor, a Black mutual aid society connected to education and racial uplift. By the time of his death in 1901, he had become a respected figure in Black community circles, though the story of the Knights of Liberty remained largely forgotten outside specialized historical discussions.
Part of the reason the organization faded from popular memory is because secret groups rarely leave behind detailed records. Another reason is that mainstream American history has often been more comfortable celebrating peaceful abolitionism than confronting the reality of Black militant resistance.
Stories about speeches, petitions, and moral debates fit more neatly into national mythology than stories about enslaved Africans secretly preparing for armed rebellion.
Yet the existence of the Knights of Liberty, whether it was as large as Dickson claimed or not, reveals something important about the era before emancipation.
Freedom was not something many enslaved Africans intended to wait for. Across the South, they were organizing, plotting, and preparing to seize it with their own hands if they had to.
Many of the enslaved were not simply waiting for freedom to arrive.
They were organizing, planning, and preparing to seize it themselves if necessary.
