Before dawn on July 2, 1839, a group of enslaved Africans chained in the hold of the Spanish schooner La Amistad broke free of their shackles, armed themselves with cane knives found in the cargo, and rose up against the crew sailing them between two Cuban ports. By the time the uprising ended, the ship's captain and cook were dead, and the roughly fifty-three surviving Africans, led by a man named Sengbe Pieh — known to history by his Spanish-given name, Cinqué — had seized control of the vessel. What followed was a two-year legal odyssey that carried the captives from a Long Island beach to the United States Supreme Court, where a former President of the United States argued for their freedom.
Kidnapped Twice Over
The people aboard La Amistad were, almost without exception, free members of Mende and other ethnic communities from the region of present-day Sierra Leone, kidnapped by slave traders and transported across the Atlantic in direct violation of Spanish law. Spain had agreed by treaty to prohibit the transatlantic slave trade after 1820, yet an illegal trade persisted for decades afterward, smuggling captives into Cuba disguised as though they were already part of the island's existing, legally recognized enslaved population. The Africans aboard La Amistad had been sold in Havana to two Spanish plantation owners, José Ruiz and Pedro Montes, who were transporting them along the Cuban coast to another port when the uprising occurred.
Cinqué and his fellow captives spared the lives of Ruiz and Montes on the condition that the Spaniards sail the ship back toward Africa. Montes, who had some knowledge of navigation, instead steered a deceptive course, sailing east by day when the Africans could observe the sun but turning the ship northwest under cover of darkness, gradually working the schooner up the Atlantic coast of North America rather than toward Sierra Leone. After weeks at sea, with food and water running low and several captives dead from illness and the earlier violence, La Amistad was sighted and boarded off Long Island, New York, by the USS Washington, a United States Navy surveying brig commanded by Lieutenant Thomas R. Gedney, near Culloden Point on August 26, 1839.
Property or People? A Case in the Courts
Gedney brought the ship and its human cargo into New London, Connecticut, setting off a complicated legal fight over what, exactly, the law should regard the Africans to be. The Spanish government, backed by Queen Isabella II's regime, demanded that the ship, its cargo, and the Africans be returned to Cuba as Spanish property, insisting the matter fell under treaty obligations between Spain and the United States governing the return of vessels and goods. Ruiz and Montes likewise claimed the Africans as their legal property under Cuban and Spanish law. Complicating matters further, Lieutenant Gedney and his crew filed a salvage claim, seeking compensation for having recovered the ship — a claim that made sense only if the Africans themselves were legally cargo rather than people.
President Martin Van Buren's administration, eager to preserve good relations with Spain and mindful of the political sensitivities of an election year in which Southern support mattered greatly, sided with the Spanish position and pressed for the swift, quiet return of the Africans to Cuba, where they would likely have faced execution or re-enslavement.
Abolitionists intervened. A coalition of activists — including the merchant and reformer Lewis Tappan, the minister Simeon Jocelyn, and the journalist Joshua Leavitt — formed what became known as the Amistad Committee, raising funds, securing legal counsel, and locating interpreters who could communicate with the Mende-speaking captives, most critically a sailor named James Covey who could translate their testimony for the American courts for the first time.
The Africans' Own Testimony
The case moved through the federal district and circuit courts in Connecticut, where the central legal question was stark: were the people aboard La Amistad enslaved property under Spanish law, or were they free individuals who had been kidnapped in violation of international treaties banning the slave trade, and who had therefore been justified in resisting their captors? Testimony gathered through Covey's translation allowed the Africans, for the first time, to describe their own kidnapping and transport in their own words before an American court.
In January 1840, federal district judge Andrew Judson ruled that the Africans had indeed been illegally enslaved — kidnapped and transported in violation of the very treaties Spain itself had signed banning the trade — and were therefore free persons, not property subject to return. He ordered that they be transported back to Africa. The Van Buren administration, still committed to the Spanish position, appealed the ruling, eventually carrying the case to the Supreme Court of the United States.
John Quincy Adams Before the Court
To argue the case before the Supreme Court, the Amistad Committee turned to the seventy-three-year-old former President John Quincy Adams, then serving as a member of the House of Representatives and one of the era's most formidable legal minds, though he had not argued before the Court in decades. Adams joined the attorney Roger Baldwin in presenting the Africans' case in February and March of 1841. Adams's argument stretched across parts of two days, an unusually lengthy oral presentation even by the standards of the period, and drew on both legal precedent and moral appeal, invoking the Declaration of Independence's assertion of natural rights as directly applicable to the captives' claim to freedom.
On March 9, 1841, the Supreme Court ruled in the Africans' favor. Justice Joseph Story, writing for the majority, affirmed the lower court's central finding: the Africans aboard La Amistad had been kidnapped in violation of international law banning the slave trade, were never legitimately enslaved under Spanish law to begin with, and were therefore free people who had been justified in resisting their unlawful captivity. The salvage claims of Gedney and his crew were allowed to proceed against the ship and its cargo, but not against the persons of the Africans themselves.
The Journey Home
Roughly thirty-five of the original captives survived to see their freedom confirmed; others had died from illness, violence, or the hardships of the voyage and their subsequent imprisonment while the case wound through the courts. With support from abolitionist and missionary organizations, the survivors sailed back to Sierra Leone in November 1841, accompanied by American missionaries who would go on to establish a mission among the Mende people, a direct outgrowth of the relationships formed during the two-year legal battle.
The Amistad case did not end slavery in the United States, nor did it resolve the broader legal status of slavery within the country's own borders, where the institution remained fully legal for another two decades. But it stood as a rare instance in which the American legal system, tested by an international incident it could not simply ignore, affirmed that kidnapped free people retained their right to resist captivity and reclaim their freedom — a principle argued, in the end, by a former President before the highest court in the land.
