The Amistad Case in New Haven: Sengbe Pieh, John Quincy Adams, and the City's Northern Conscience Tradition

In August 1839, the schooner La Amistad was found drifting off the coast of Long Island by an American naval vessel, its sails ragged, its crew dead, its cargo hold filled with fifty-three West African captives who had taken the ship from their Spanish enslavers two months earlier. The captives, almost all of them members of the Mende people from what is today Sierra Leone, had been illegally seized in Africa, transported across the Atlantic in violation of every international slave-trade treaty in force, and were being moved between Cuban ports when their leader — a young farmer named Sengbe Pieh, known in American newspapers by his Spanish name Cinque — broke free from the chains, armed himself with a sugar cane knife, freed the others, and led an uprising in which the Spanish captain and cook were killed. The captives ordered the surviving crewmen to sail east toward Africa. The crewmen, navigating by the sun by day and steering north and west at night, deceived their captives until the ship eventually drifted into American territorial waters.

The American naval captain who seized La Amistad towed the ship into New London, Connecticut, on August 26, 1839, expecting to claim salvage rights to the cargo, which Spanish law treated as enslaved property worth several hundred thousand dollars. The Africans were transported to New Haven and locked into a jail at Church and Court Streets, immediately adjacent to the New Haven Green, where they would be held for the next eighteen months. The case eventually reached the United States Supreme Court in February 1841, where the captives were defended by a 73-year-old former president, John Quincy Adams, whose three-and-a-half-hour argument won them their freedom. Adams argued that the captives had been illegally enslaved under existing international treaties, that they were free human beings who had legitimately defended themselves against unlawful imprisonment, and that the United States had no business returning them to slavery. The Supreme Court ruled 7-1 to release them.

New Haven civil rights landmarks

This episode is not just a historical curiosity, and it is not just a Steven Spielberg movie. The Amistad case sits at the geographic and symbolic center of a longer thread of New Haven civil-rights history that connects the 1839 case to the 19th-century abolitionist movement, the Underground Railroad routes through Connecticut, the Yale Divinity School's role in 19th-century reform politics, and the 1970 Black Panther trial that drew 12,000 protesters to the New Haven Green. These episodes are not separate. They form a single continuous tradition that the city has only recently — within the last forty years — started memorializing publicly, and that international students walking the New Haven Green today can read in the bronze, the stone, and the absences if they know what to look for.

The Eighteen Months in the Church Street Jail

Once Sengbe Pieh and his fifty-two fellow captives arrived in New Haven in late August 1839, they were imprisoned at Church and Court Streets — a building that no longer stands; the site is currently a parking lot adjacent to the federal courthouse. Local abolitionists, alerted within days, organized a multi-pronged response that would shape American abolitionist organizing for the next two decades.

The most important figure was Lewis Tappan, a New York merchant who organized a legal defense fund within weeks. Tappan was joined by Roger Sherman Baldwin, a New Haven attorney (grandson of the Roger Sherman who had signed both the Declaration of Independence and the Constitution), who would serve as lead defense counsel in the lower courts. Tappan and Baldwin assembled a defense team, raised funds for the captives' food and clothing, and arranged for Yale Divinity School professors and students to teach the captives English. Josiah Willard Gibbs Sr., a Yale linguistics professor, walked the New Haven docks until he found a Mende-speaking sailor — James Covey, a former Mende slave freed by the Royal Navy — to serve as translator. Without Covey, the captives could not have given testimony, identified themselves by name, or communicated with their defenders.

The Yale Divinity School connection is central. Founded in 1822, the school was through the 1830s and 1840s a stronghold of New England abolitionism. Faculty and students from the Yale Divinity School volunteered to instruct the captives in English and Christianity (the latter with mixed results — Sengbe Pieh and the other Mende showed limited interest in conversion). Divinity School students walked from the school to the jail several times a week. By the time the case reached the Supreme Court, the captives had acquired enough English to communicate directly with their defenders.

The case wound through the federal court system relatively quickly by 1839 standards. The first hearing was at Hartford in September 1839, the second at New Haven in November, the District Court ruling in January 1840 (the first court to free the captives), the Circuit Court appeal in May 1840 (upholding), and finally the Supreme Court appeal in February 1841. The Spanish government, American president Martin Van Buren (who supported Spanish claims), and salvage claimants all pressed for the captives' return to Cuba and to slavery.

John Quincy Adams's Supreme Court Argument

The decision to engage John Quincy Adams as appellate counsel was Tappan's. Adams was 73, had served as the sixth President of the United States, had returned to political life as a member of Congress from Massachusetts in 1830, and had become through the 1830s the most prominent congressional critic of slavery — opposing the "gag rule" that prevented House debate on antislavery petitions. Adams was reluctant at first; his health was poor, his legal practice limited. He eventually agreed, partly because he believed the case was a test of constitutional principle.

Adams's Supreme Court argument over February 24-March 1, 1841 ran for eight and a half hours across two days — one of the longest sustained Supreme Court arguments in American legal history. Adams argued that the captives had been illegally enslaved under the 1817 Anglo-Spanish treaty outlawing the international slave trade; that their original enslavement was therefore not legally valid; that their resistance against the Spanish crew was lawful self-defense; and that the United States had no constitutional authority to return them to bondage.

The ruling on March 9, 1841 went 7-1 for the captives. The opinion, written by Justice Joseph Story, ordered them released. The slaveholding justices — including Roger Taney, who would later author the Dred Scott opinion — joined the majority because the case was decided narrowly on treaty grounds rather than broader antislavery principle.

Sengbe Pieh and approximately 35 surviving Mende — several had died of disease during the imprisonment — sailed for Sierra Leone in November 1841, accompanied by abolitionist missionaries. The American Missionary Association's Mende Mission that resulted became the foundation of long-term Yale Divinity School engagement with West Africa.

The Amistad Memorial: A Late Memorialization

For nearly 150 years after the case, New Haven did not publicly memorialize the Amistad episode. The site of the jail was demolished and forgotten. The 1839 site was a parking lot.

In 1990, after a multi-year campaign by Yale historians, local activists, and the Amistad Committee, the city installed the Amistad Memorial — a fourteen-foot-high bronze sculpture by Ed Hamilton depicting Sengbe Pieh in three poses (in chains as a captive, leading the uprising, and as a free man returning to Africa) — at the site of the former jail at Church and Court, on the eastern edge of the New Haven Green. The memorial is now the most important physical landmark of African American history on the Green, and serves as the focal point for an annual commemoration each February.

The memorial's late installation — 151 years after the case — is itself a significant historical fact. New Haven, like most American cities, did not begin systematically memorializing African American history until the late 20th century. The 1990 installation reflected a national shift that included the National Underground Railroad Freedom Center (2004) and the National Memorial for Peace and Justice (2018). The Amistad Memorial was both belated and consistent with broader patterns.

The Underground Railroad in Connecticut

The Amistad case sat within a broader Connecticut abolitionist context. Connecticut was officially a free state by the 1820s — a gradual emancipation act in 1784 had freed children born to enslaved mothers when they reached age 25 (later 21), with full abolition completed by 1848. But Connecticut was a substantial Underground Railroad corridor through the 1830s-1850s, connecting Mid-Atlantic free states to Massachusetts, Vermont, and Canadian routes for fugitive slaves.

The routes through Connecticut were not literal railroads — the term referred to the informal network of safe houses and abolitionist organizations that helped fugitive slaves move north. New Haven was a documented stop, with several Yale Divinity School professors and Congregationalist church members serving as conductors. Farmington, 40 miles north, was particularly active — the Farmington Underground Railroad is among the best-documented in the country, with surviving safe houses still preserved as historical sites.

The Connecticut Underground Railroad was substantially organized through Congregationalist churches, particularly those affiliated with Yale Divinity School graduates serving as ministers across the state. The same theological community that produced the Yale faculty teaching English to the Amistad captives also produced the Connecticut clergy who hid fugitives in church basements and drove wagons of refugees north under cover of night.

The historical irony is that the same university whose name memorializes a slave-trading East India Company governor (Elihu Yale) also produced — through its Divinity School — one of the most concentrated networks of Northern antislavery activism in 19th-century America. Yale's institutional relationship to slavery is genuinely complicated, and the Amistad case is one of the moments when the institution was, in significant part, on the right side of the question.

The 1970 New Haven Black Panther Trial

The Amistad-Underground Railroad-abolitionist tradition continued, in modified forms, into the 20th-century civil rights era. The single most consequential 20th-century New Haven civil-rights event was the 1970 trial of Bobby Seale and Ericka Huggins, two leaders of the Black Panther Party, on charges related to the murder of fellow Panther Alex Rackley in May 1969.

The case was contested at the time. Rackley had been murdered by other Panthers in New Haven on suspicion of being an FBI informant. Bobby Seale, the national chairman, had been in New Haven briefly at the time of the killing but was not directly accused of committing the murder. Ericka Huggins, a New Haven Panther organizer, was more directly involved. The state's case argued that Seale had ordered the killing; the defense argued that the FBI had infiltrated the Panther leadership and that the trial was a political prosecution.

The trial attracted national attention. On May Day 1970 — May 1, 1970 — approximately 12,000 protesters, many of them students from Yale, Wesleyan, Trinity, and other regional colleges, gathered on the New Haven Green demanding that the charges be dropped. Yale president Kingman Brewster Jr. made a public statement that he was "skeptical of the ability of black revolutionaries to achieve a fair trial anywhere in the United States" — a statement that drew national criticism but helped maintain civil order. The protest, despite its size, remained largely peaceful, in significant part because Brewster, the Yale faculty, the New Haven mayor, and Panther leadership all worked together to prevent escalation.

The trial ended in mistrial in May 1971 after the jury deadlocked, and the prosecution declined to retry. Seale and Huggins were released. The 1970 Black Panther episode is geographically continuous with the Amistad case. The trial took place in the federal courthouse on Church Street — adjacent to the site of the former jail where Sengbe Pieh had been held 131 years earlier. The May Day protest gathered on the New Haven Green — the same Green where the colonial Puritan founders had imagined a holy city in 1638. The geographic stack of these episodes — Puritan, abolitionist, civil-rights — is concentrated in roughly six city blocks at the center of New Haven.

The Conscience Tradition and Its Public Memorialization

The thread connecting these episodes — the Amistad case, the Connecticut Underground Railroad, the Yale Divinity School's reform politics, the 1970 Black Panther trial — is what some New Haven historians call the Northern Conscience tradition. The tradition is real, but genuinely complicated, and its public memorialization has been belated and partial.

The complications include Yale's own slaveholding past — the university owned enslaved people in its earliest decades, several buildings were named for slaveholders (Calhoun College was renamed Hopper College in 2017 in recognition of this), and the institution profited indirectly from slavery through the 18th and 19th centuries. They include Connecticut's slow path to emancipation — the state did not fully abolish slavery until 1848, decades after Massachusetts and other New England states. They include the political mixed-record of the abolitionist tradition itself, which combined principled antislavery commitment with paternalism, evangelical conversion politics, and limited engagement with what Black freedom would require beyond the technical end of slavery.

For an international student walking the New Haven Green and the surrounding streets, the layered history is legible if you know where to look. The Amistad Memorial at Church and Court bears the bronze image of Sengbe Pieh. The US District Court a few feet away is where 1970 protests against political prosecution took place. The Yale Divinity School half a mile north was the institutional base from which 19th-century abolitionist clergy organized their networks. The Green itself, the central square of the 1638 Puritan plan, has been the gathering ground for protest, mourning, and commemoration for nearly four centuries.

The tradition does not redeem Yale's slavery-era complications, and it does not redeem New Haven's 20th-century history of segregated housing and ongoing patterns of racial inequality. What it does is establish that, alongside those complications, there is a substantive and continuous record of New Haven institutions and individuals committing themselves to antislavery and civil-rights work over roughly 200 years. That record is now publicly visible in ways it was not until recent decades, and the visibility itself is part of what international students see when they walk the Green and notice the Amistad Memorial standing at the eastern edge.
