The anti-abolitionist riots of 1834, (also Farren Riot or Tappan Riot), occurred in New York City over a series of four nights, beginning on July 7, 1834. Their deeper origins lay in the combination of nativism and abolitionism among the Protestants who had controlled the booming city since the American Revolutionary War, and fear and resentment of blacks among the growing underclass of Irish immigrants and their kin. In 1827 Britain repealed legislation controlling and restricting emigration from Ireland, and 20,000 Irish emigrated; by 1835 over 30,000 Irish arrived in New York annually.
In May and June 1834, the silk merchants and ardent abolitionists Arthur Tappan and his brother Lewis stepped up their agitation for the abolition of slavery by underwriting the formation in New York of a female anti-slavery society. Arthur Tappan drew particular attention by sitting in his pew (at Samuel Cox's Laight Street Church) with Samuel Cornish, a mixed-race clergyman of his acquaintance. By June, lurid rumors were being circulated by the champion of repatriating "colonization", James Watson Webb, through his newspaper Courier and Enquirer: abolitionists had told their daughters to marry blacks, black dandies in search of white wives were promenading Broadway on horseback, and Arthur Tappan had divorced his wife and married a black woman.
Reports appearing in London in The Times, taken from American newspapers, cite as the triggering cause a disturbance following a misunderstanding at the Chatham Street Chapel, a former theater converted with money from Arthur Tappan for the ministry of Charles Grandison Finney. Edwin G. Burrows and Mike Wallace note that on July 4, an integrated group that had convened at the chapel to celebrate New York's emancipation (in 1827) of its remaining slaves was dispersed by angry spectators. The celebration was rescheduled for July 7. According to The Times, the secretary of the New York Sacred Music Society, which leased the chapel on Monday and Thursday evenings, gave a black congregation leave to use it on July 7 to hold a church service. This service was in progress when members of the society who were unaware of the arrangement arrived and demanded to use the facility. Though one member of the congregation called for the chapel to be vacated, most refused. A 'fracas' ensued "which resulted in the usual number of broken heads and benches". Burrows and Wallace note that constables arrived and arrested six African Americans. Webb's paper described the event as a Negro riot resulting from "Arthur Tappan's mad impertinence", and the Commercial Advertiser reported that gangs of blacks were preparing to set the city ablaze.
