The Cincinnati riots of 1836 were caused by racial tensions at a time when African Americans, some of whom had escaped from slavery in the Southern United States, were competing with whites for jobs. The racial riots occurred in Cincinnati, Ohio, United States in April and July 1836 by a mob of whites against black residents. These were part of a pattern of violence at that time. A severe riot had occurred in 1829, led by ethnic Irish, and another riot against blacks broke out in 1841. After the Cincinnati riots of 1829, in which many African Americans lost their homes and property, a growing number of whites, such as the "Lane rebels" who withdrew from the Cincinnati Lane Seminary en masse in 1834 over the issue of abolition, became sympathetic to their plight. The anti-abolitionist rioters of 1836, worried about their jobs if they had to compete with more blacks, attacked both the blacks and white supporters.
Background
Blacks in southern Ohio suffered from severe restrictions to their freedom due to the Black Codes passed by the state legislature in 1804 and 1807. Under this legislation, the testimony of any black person was invalid in a court of law. A black person could not defend himself against a charge, and could not bring action against a white man. If he managed to acquire property, he was taxed for school support, but his children were not allowed to attend the schools. A black person moving to the state was required to obtain the signatures of two white men on a $500 bond. The Fugitive Slave Act of 1793 was enforced rigorously, and steep fines were imposed on anyone who assisted a runaway slave.

Despite this, growing numbers of black people moved into the state within the first three decades, which aggravated tensions. In 1819 a citizen asked for relief "from the hordes of idle runaway blacks of both sexes, who are sauntering about the streets at all hours of the day". Some who were opposed to slavery but alarmed at the social consequences of abolition argued for colonization schemes, by which free blacks would be shipped to Liberia, as proposed by the American Colonization Society, which revived the Black Code of Ohio so as to stimulate emigration; or to Haiti (which was trying to recruit American blacks); or to the west coast of North America. Others were willing to risk public disapproval and fight for the rights of free blacks.

James Gillespie Birney, a former slave owner from Alabama, had become an abolitionist. In January 1836 he set up The Philanthropist, a newspaper sponsored by the Ohio Anti-Slavery Society. At first, the newspaper was printed in nearby New Richmond. It was distributed across the Ohio River in Kentucky and was filled with anti-slavery propaganda. This angered local Cincinnati businessmen, who were keen to do business with the Southern states.

In late January 1836, some of the most prominent citizens organized a meeting opposing abolition; it was attended by over 500 people. Birney attended the meeting but was not allowed to give his views.
April riot
In April, Birney moved his press to Cincinnati. On 11 April 1836, a mob entered a black community, attacked people, burned buildings, and forced many of the occupants to leave their homes. Irish rioters burned down a tenement in the Ohio River bottom section of the lower West End. Several blacks died. The riot was not brought under control until the governor intervened and declared martial law. The anti-abolitionist paper the Daily Cincinnati Republican described the tenement that was burned as "notorious as a place of resort of rogues, thieves, and prostitutes - black and white". The paper said the arson was viewed by a "large concourse of our citizens" who made no effort to extinguish the flames.
July riots
On 5 July, a race riot began when African Americans observed an Independence Day celebration. Although this had long been the custom of the blacks, some whites considered it as a demonstration that the blacks wanted full integration. James Birney attended the event, which helped stir up passions as he was a noted abolitionist. On 12 July 1836, about forty men broke into the building housing Birney's press and destroyed it. The men were described as "respectable and wealthy gentlemen". They shredded newspapers, broke the press in pieces, and dragged the damaged parts through the streets. Birney lost an estimated $1,500 in damage. He agreed to continue producing the paper only when his property was guaranteed to the value of $2,000 by the Ohio Anti-Slavery Society.
