The anti-abolitionist riots of 1834 (also Farren Riot or Tappan Riot) take place in New York City over a series of four nights, beginning on July 7, 1834.
Their deeper origins lie in the combination of nativism and abolitionism among Protestants who have 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, the UK repeals legislation controlling and restricting emigration from Ireland, and twenty thousand Irish emigrate; by 1835 over thirty thousand Irish will arrive in New York annually.
