The following is a partial list of riots and protests involving violent disorder that have occurred in Philadelphia:
In the broader context of racism against Black Americans and racism in the United States, mass racial violence in the United States consists of ethnic conflicts and race riots, along with such events as:
The Gordon Riots of 1780 were several days of rioting in London motivated by anti-Catholic sentiment. They began with a large and orderly protest against the Papists Act 1778, which was intended to reduce official discrimination against British Catholics enacted by the Popery Act 1698. Lord George Gordon, head of the Protestant Association, argued that the law would enable Catholics to join the British Army and plot treason. The protest led to widespread rioting and looting, including attacks on Newgate Prison and the Bank of England and was the most destructive in the history of London.
A riot or mob violence is a form of civil disorder commonly characterized by a group lashing out in a violent public disturbance against authority, property, or people.
The Philadelphia nativist riots were a series of riots that took place on May 6—8 and July 6—7, 1844, in Philadelphia, Pennsylvania, United States and the adjacent districts of Kensington and Southwark. The riots were a result of rising anti-Catholic sentiment at the growing population of Irish Catholic immigrants. The government brought in over a thousand militia—they confronted the nativist mobs and killed and wounded hundreds of anti-Catholic rioters.
Red Summer was a period in mid-1919 during which white supremacist terrorism and racial riots occurred in more than three dozen cities across the United States, and in one rural county in Arkansas. The term "Red Summer" was coined by civil rights activist and author James Weldon Johnson, who had been employed as a field secretary by the National Association for the Advancement of Colored People (NAACP) since 1916. In 1919, he organized peaceful protests against the racial violence.
Violent attacks by armed mobs of White Americans against African Americans in Atlanta, Georgia, began after newspapers, on the evening of September 22, 1906, published several unsubstantiated and luridly detailed reports of the alleged rapes of 4 local women by black men. The violence lasted through September 24, 1906. The events were reported by newspapers around the world, including the French Le Petit Journal which described the "lynchings in the USA" and the "massacre of Negroes in Atlanta," the Scottish Aberdeen Press & Journal under the headline "Race Riots in Georgia," and the London Evening Standard under the headlines "Anti-Negro Riots" and "Outrages in Georgia." The final death toll of the conflict is unknown and disputed, but officially at least 25 African Americans and two whites died. Unofficial reports ranged from 10–100 black Americans killed during the massacre. According to the Atlanta History Center, some black Americans were hanged from lampposts; others were shot, beaten or stabbed to death. They were pulled from street cars and attacked on the street; white mobs invaded black neighborhoods, destroying homes and businesses.
The 1943Detroit race riot took place in the U.S. city of Detroit, Michigan from the evening of June 20 through to the early morning of June 22. It occurred in a period of dramatic population increase and social tensions associated with the military buildup of U.S. participation in World War II, as Detroit's automotive industry was converted to the war effort. Existing social tensions and housing shortages were exacerbated by racist feelings about the arrival of nearly 400,000 migrants, both African-American and White Southerners, from the Southeastern United States between 1941 and 1943. The new migrants competed for space and jobs, as well as against European immigrants and their descendants. The riot escalated in the city after a false rumor spread that a mob of whites had thrown a black mother and her baby into the Detroit River. Blacks looted and destroyed white property as retaliation. Whites overran Woodward to Veron where they proceeded to tip over 20 cars that belonged to black families.
The Chicago race riot of 1919 was a violent racial conflict between white Americans and Black Americans that began on the South Side of Chicago, Illinois, on July 27 and ended on August 3, 1919. During the riot, 38 people died. Over the week, injuries attributed to the episodic confrontations stood at 537, two thirds Black and one third white; and between 1,000 and 2,000 residents, most of them Black, lost their homes. Due to its sustained violence and widespread economic impact, it is considered the worst of the scores of riots and civil disturbances across the United States during the "Red Summer" of 1919, so named because of its racial and labor violence. It was also one of the worst riots in the history of Illinois.
The Lombard Street riot was a three-day race riot in Philadelphia, Pennsylvania, in 1842. The riot was the last in a 13-year period marked by frequent racial attacks in the city. It started on Lombard Street, between Fifth and Eighth streets.
The Detroit race riot of 1863 occurred on March 6, 1863, in the city of Detroit, Michigan, during the American Civil War. At the time, the Detroit Free Press reported these events as "the bloodiest day that ever dawned upon Detroit." It began due to unrest among the working class related to racism and the military draft, which was heightened after the Emancipation Proclamation was issued by President Abraham Lincoln. Based in a free state, some recent immigrants and other workers resented being drafted for a war that they thought was waged for the benefit of slaves in the Southern United States, and they feared competition from Black people.
The 1956 anti-Tamil pogrom, also known as the Gal Oya riots, was the first organised pogrom against Sri Lankan Tamils in the Dominion of Ceylon. It began with anti-Tamil rioting in Colombo, followed by anti-Sinhalese violence in Batticaloa. The worst of the violence took place in the Gal Oya valley, where local majority Sinhalese colonists and employees of the Gal Oya Development Board commandeered government vehicles, dynamite and weapons and massacred minority Tamils. It is estimated that over 150 people, mostly Tamils, had died during the violence. The police and army were eventually able to bring the situation under control.
Riots in Detroit, Michigan, have occurred since the city was founded in 1701. This area was settled by various ethnicities following thousands of years of indigenous history. During the colonial period, it was nominally ruled by France and Great Britain before the border was set in the early 19th century and it became part of the United States. The first riot, social unrest related to enabling fugitive slaves to escape to Canada, was recorded in 1833. Other riots were related to business protests, unions, and other issues.
The Washington race riot of 1919 was civil unrest in Washington, D.C. from July 19, 1919, to July 24, 1919. Starting July 19, white men, many in the armed forces, responded to the rumored arrest of a black man for rape of a white woman with four days of mob violence against black individuals and businesses. They rioted, randomly beat black people on the street, and pulled others off streetcars for attacks. When police refused to intervene, the black population fought back. The city closed saloons and theaters to discourage assemblies. Meanwhile, the four white-owned local papers, including the Washington Post, fanned the violence with incendiary headlines and calling in at least one instance for mobilization of a "clean-up" operation. After four days of police inaction, President Woodrow Wilson ordered 2,000 federal troops to regain control in the nation's capital. But a violent summer rainstorm had more of a dampening effect. When the violence ended, 15 people had died: at least 10 white people, including two police officers; and around 5 black people. Fifty people were seriously wounded and another 100 less severely wounded. It was one of the few times in 20th-century riots of whites against blacks that white fatalities outnumbered those of black people. The unrest was also one of the Red Summer riots in America.
The 1917 Chester race riot was a race riot in Chester, Pennsylvania that took place over four days in July 1917. Racial tensions increased greatly during the World War I industrial boom due to white hostility toward the large influx of southern blacks who moved North as part of the Great Migration. The riot began after a black man walking in a white neighborhood with his girlfriend and another couple bumped into each other. This led to a fight in which the black man stabbed and killed the white man. In retaliation, white gangs targeted and attacked blacks throughout the city. Four days of violent melees involving mobs of hundreds of people followed. The Chester police along with the Pennsylvania National Guard, Pennsylvania State Police, mounted police officers and a 150-person posse finally quelled the riot after four days. The riot resulted in 7 deaths, 28 gunshot wounds, 360 arrests and hundreds of hospitalizations.
The 1834 Philadelphia race riot, also known as the Flying Horses riot, was an instance of communal violence in Philadelphia, Pennsylvania, United States. The riot, in which a mob of several hundred white people attacked African Americans living in the area, began on the evening of August 12 and lasted for several days, dying down by August 14.
