The 1733 slave insurrection on St. John (Danish: Slaveoprøret på Sankt Jan), also called the Slave Uprising of 1733, began on November 23, 1733, on the island of Sankt Jan in the Danish West Indies (now St. John, U.S. Virgin Islands). About 150 enslaved Africans, many from the Akwamu people of present-day Ghana, rose up against plantation owners and overseers.
Led in part by Breffu, an enslaved woman from Ghana, the rebellion lasted for months—continuing into August 1734—making it one of the earliest and longest sustained slave revolts in the Americas. The insurgents seized the fort at Coral Bay and gained control over most of the island. Rather than destroying plantations, they aimed to take over the estates and continue crop production under their own authority.
By late May 1734, planters regained control after the rebels were defeated by several hundred French and Swiss troops sent from Martinique in April. After the main fighting ended, local militia forces continued hunting down rebels who had fled into the hills as maroons. Officials declared the uprising fully suppressed in late August 1734.
Background
The Danish slave system on St. John
Denmark claimed St. John in 1718 to develop plantations producing sugar, indigo, and cotton. Labor shortages among European settlers made enslaved African labor central to the economy. By mid-1733, the island held more than 1,000 enslaved Africans, far outnumbering the European population. Many plantations were owned by absentee landlords living on St. Thomas, leaving overseers in charge—conditions that often intensified cruelty.
The Akwamu and forced migration
Denmark’s slave trade expanded along the West African coast near Accra, where the Akwamu had once been a dominant regional power. After political upheaval and defeat in the early 1700s, many Akwamu captives were sold into slavery and transported to plantations in the Danish West Indies, including St. John.
Drought, marooning, and harsh laws
In 1733, environmental hardship—drought, storms, and crop failure—pushed many enslaved people to flee plantations and form maroon communities in the island’s interior. Colonial authorities responded with the Slave Code of 1733, imposing severe punishments meant to prevent escape and rebellion.
The Revolt
November 23, 1733: The outbreak
The uprising began at plantations in the Coral Bay region. Rebels gained entry to the fort under routine pretenses, concealed weapons, and killed most of the soldiers stationed there. Cannon shots from the fort signaled the wider revolt, and rebels quickly expanded control across nearby estates. They moved across the island, targeting settlements while largely avoiding the widespread destruction of property—consistent with their plan to rule and maintain production.
Resistance and flight
Some planters and loyal enslaved people resisted at certain estates, allowing groups of Europeans to escape by boat to St. Thomas. As the rebellion spread, many survivors fled the island.
Suppression and Aftermath
Danish officials requested military assistance from French authorities in Martinique. French ships arrived on April 23, 1734, bringing several hundred troops whose superior arms and numbers broke rebel control. By May 27, plantation rule had been restored. The final phase was a prolonged manhunt for remaining maroons, ending with the capture of the last holdouts and an official declaration on August 25, 1734, that the rebellion was over.
The uprising caused significant loss of life and disrupted the plantation economy. In its wake, some landowners relocated to St. Croix, newly acquired by Denmark in 1733, accelerating development there.
“Freedom” in the century that followed
In the years after the revolt, some individuals gained freedom through exceptional circumstances. One notable example was Franz Claasen, described as a “loyal slave,” who received a land deed in 1738, becoming the first recorded “Free Colored” landowner on St. John.
Denmark-Norway ended the transatlantic slave trade to its Caribbean colonies on January 1, 1803, but slavery continued. Enslaved people sometimes escaped to nearby British islands such as Tortola, where British authorities offered refuge. Pressure for abolition grew through petitions and resistance.
On July 3, 1848, enslaved Afro-Caribbeans on St. Croix staged a mass, nonviolent demonstration demanding freedom. Governor-General Peter von Scholten declared emancipation across the Danish West Indies—114 years after the St. John insurrection.
In modern times, remembrance efforts continue. For example, the Consolidated Appropriations Act, 2023 directed the placement of a commemorative plaque at Ram Head Peak, recognizing the history and legacy of the rebellion.
