Also known as the, “Negro Plot of 1741.”
Today, when we look back at the Salem Witch Trials, we shake our collective heads and tell ourselves that the execution of innocent men and women in 1692 was aberrational. “Never again,” we say. Half a century later, however, it happened again, but this time it wasn’t witches—it was the alleged conspiracy of black slaves in New York City to burn down the city and seize control of the government. The public hysteria over the discovery of the alleged “Negro Plot” went far beyond the hysteria of the people of Salem in 1692, and lasted far longer. Yet, most Americans today have no knowledge of the events of 1741: mass arrests, imprisonments, interrogations, convictions, and executions of scores of enslaved persons accused of participating in the plot, based on “evidence” that was questionable at best. These grisly executions were the result of a massive miscarriage of justice perpetrated by a group of judges, prosecutors, witnesses and jurors whose racial biases against blacks were glaringly apparent. It was on May 30, 1741 that the first accused African-American leaders of the “Plot” were tried and convicted of conspiracy, then burned at the stake before an enormous crowd of onlookers. These first two men, named Cuffee and Quaco—were two of dozens of black slaves who were summarily executed after show trials conducted with little or no regard for the civil rights of the defendants. It is estimated that over half of the male slaves in New York City were jailed in the process, with many of them escaping execution only by being shipped off to the West Indies, where many died from the appalling conditions of life that enslaved persons working in the sugar plantations experienced there.

The main source of information about the 1741 trials is a journal written by Daniel Horsmanden, an ambitious political figure in New York who became the leader of the investigation into the alleged “Negro Plot.” The journal was published in 1744 under the title “A Journal of the Proceedings in the Detection of the Conspiracy Formed by Some White People, in Conjunction with Negro and Other Slaves” (available online for free on archive.org).
The “Negro Plot” first came to light—or was invented—based upon widespread speculation that a series of fires in New York City in March through May, 1741 were not accidental, but part of a conspiracy to burn the city down, take control of the government, and install one of the black community’s own—a man named Caesar—as the Governor. The plot thickened when a white prostitute named Peggy (who had given birth to a child by Caesar), implicated Caesar as a ringleader of the plot. Other white people also played a role in the first wave of accusations: Mary Burton, a 16-year-old servant girl, accused her master, John Hughson (also white) of being the leader of the conspiracy, and of hosting meetings attended by a large number of enslaved blacks at his tavern. Hughson was suspected of trading in stolen property and other misdeeds, so he was a convenient target for these accusations. A number of poor working-class white men were also accused of plotting with enslaved blacks to take the white bosses of New York who were oppressing them. It was Mary Burton who ultimately gave sworn testimony that Hughson had agreed to help Cuffee, Caesar and another black slave, Prince, burn the city to the ground, and in exchange for his help, Hughson would be named “King” of the new government. Burton’s alarming testimony led to an all-out witch-hunt, as New York’s lieutenant-governor issued a proclamation offering substantial cash rewards for information on any other persons involved in setting the fires. More accusations followed, and many blacks were arrested and jailed on trumped-up charges. Not surprisingly, some of these men decided to turn “state’s evidence” and accuse others—shades of the Salem Witch Trials, indeed.
By mid-May, vigilante justice was already taking place in New York, with two black men having been burned at the stake on May 3, and two more—Caesar and Prince—hanged on May 11. It was only then that Daniel Horsmanden commenced the first of a series of show trials of various slaves implicated in the conspiracy. On May 29, the trial against Quaco and Cuffee began, with Horsmanden serving as one of the three judges who were to decide their fate. The two defendants pled not guilty, but the trial was a farce: by the end of the day they had been found guilty and were sentenced to be burned at the stake. The next day, the sentence was gruesomely carried out. One account said that “the prisoners were followed by a riotous crowd of New Yorkers, anxious to watch them burn.” Before dying, the two men allegedly confessed to their crimes, and implicated many more black men in the conspiracy. Still, no mercy was shown. After being burned alive, they were unceremoniously buried in the nearby African Burial Ground.

More trials and more executions followed. In total, some 30 or 40 black slaves were either hanged or burned at the stake. Four white people also were hanged, including Hughson and a Catholic priest named John Ury, who was allegedly involved in the conspiracy in order to re-establish Catholicism as the prevailing religion in New York after the city was destroyed.
What became of Horsmanden? Incredibly, perhaps, he went on to become the Chief Justice of the Supreme Court in the Province of New York. At the time of the trials in 1741, he already had been serving as the Recorder of New York City and one of the justices of the Supreme Court. He also served on the Governor’s Executive Council from 1733 to 1747, and then from 1755 to 1776. He led a long and apparently untroubled life, dying in 1778 at the age of 87.
Today, the actual facts of what happened in 1741 are elusive. One fact that is undisputed is that there was a series of fires in 1741; not much more than that is certain, unless one accepts as true the facts set forth in Daniel Horsmanden’s journal (a dubious proposition, to be sure). It is unarguable that a number of witnesses swore that there was a conspiracy, but other witnesses denied that any such conspiracy existed. In many instances, the witness testimony was entirely contradictory, but no serious effort was undertaken to sort out these major evidentiary discrepancies. Verdicts were rendered swiftly and mercilessly. Like the Salem Witch Trials, the “Negro Plot” trials were a travesty of justice, and represent one of the darkest chapters in the history of New York City.
