New York Conspiracy of 1741: Mass Hysteria Leads to 34 Executions on Dubious Testimony

Beginning in March 1741, a series of fires in New York City — starting with Fort George on March 18, followed by fires across the city — triggered a citywide panic. Authorities arrested John Hughson, a tavern keeper whose establishment was frequented by sailors and enslaved people. A sixteen-year-old Irish indentured servant named Mary Burton, arrested on theft charges, was promised a reward of £100 and began providing testimony about an alleged conspiracy of enslaved people and poor whites to burn the city, kill the white men, seize white women, and install a new king. Burton's testimony repeatedly expanded only under pressure, and she later told neighbors that 'there was no plot.' Nevertheless, New York authorities executed 13 enslaved people by burning at the stake, 17 by hanging, executed 4 white people, and transported approximately 70 enslaved people to the Caribbean. The victims included Caesar, a Black man hanged despite weak evidence, and John Ury, a Latin teacher accused of being a Catholic priest fomenting rebellion. Contemporary historians largely conclude the conspiracy existed primarily in the minds of authorities seeking to explain the fires and reassert racial control over a city in which approximately 1,700 Black people lived alongside 7,000 whites.
