List of incidents of political violence in Washington, D.C.

There have been numerous incidents of political violence in Washington, D.C., the capital of the United States, as well as in the greater Washington Metropolitan area.

19th century



 * August 24, 1814: Burning of Washington: British forces led by George Cockburn invaded and occupied Washington during the Chesapeake campaign of the War of 1812, after defeating an American force at Bladensburg. In retaliation for acts of destruction by American troops in the Canadas, Cockburn's forces burnt several government buildings in the city, including the White House and the United States Capitol. The occupation only lasted for approximately 26 hours as a storm led to the British abandoning the city. To this date, it remains the only time since the American Revolutionary War that a foreign power has captured and occupied the capital of the United States.
 * April 13, 1832: Sam Houston confronted Representative William Stanbery (OH-08) in Washington, D.C. and beat him repeatedly with a hickory walking stick after Stanbery accused him of profiteering off Andrew Jackson's forced relocation of Native Americans. During the fight Stanbery pulled a gun, placed it on Houston's chest, and pulled the trigger, but the gun misfired. Houston was arrested and charged with breaching the privileges of the House by assaulting Stanbery for remarks made from the floor.
 * January 30, 1835: Just outside the U.S. Capitol, house painter Richard Lawrence aimed two flintlock pistols at President Andrew Jackson, but both misfired: one of them while Lawrence stood within 13 ft of Jackson, and the other at point-blank range. Lawrence was apprehended after Jackson beat him down with a cane. At trial, Lawrence was found not guilty by reason of insanity and spent the remainder of his life in insane asylums.
 * June 20, 1854: A fight between Representatives William M. Churchwell (TN-02) and William Cullom (TN-04) erupted on the floor of the U.S. House of Representatives. The difficulty between the two began a month earlier during a debate of the pro-slavery Kansas–Nebraska Act. Churchwell accused Cullom and Senator John Bell (TN) of defending the Missouri Compromise of 1820. The confrontation led to a resolution permitting the House to expel a representative who brings a concealed weapon into the chamber.
 * May 22, 1856: Caning of Charles Sumner: Abolitionist Senator Charles Sumner (MA) was savagely beaten with a cane and nearly killed by pro-slavery Representative Preston Brooks (SC-04) on the floor of the U.S. Senate in retaliation for a speech criticizing slavery. It has been considered symbolic of the "breakdown of reasoned discourse" and the use of violence that eventually led to the American Civil War.
 * April 14, 1865: Assassination of Abraham Lincoln: President Abraham Lincoln was assassinated by John Wilkes Booth while attending the play Our American Cousin at Ford's Theatre. Shot in the head as he watched the play, Lincoln died the following day at 7:22   a.m. in the Petersen House opposite the theater. He was the first U.S. president to be assassinated, with his funeral and burial marking an extended period of national mourning. Occurring near the end of the American Civil War, the assassination was part of a larger conspiracy intended by Booth to revive the Confederate cause by eliminating the three most important officials of the U.S. government: the president, the vice president, and the secretary of state. After a dramatic initial escape, Booth was killed at the climax of a 12-day manhunt. His accomplices, Lewis Powell, David Herold, George Atzerodt and Mary Surratt, were later hanged for their roles in the conspiracy.
 * June 14, 1866: A debate between Representative Josiah Grinnell (IA) and Representative Lovell Rousseau (KY) over a bill intended to increase the power of the Freedmen's Bureau devolves into both men insulting each other. Rousseau would insult the state of Iowa while Grinnell would insult the state of Kentucky alongside questioning Rousseau's military record. On June 14th Rosseau would approach Grinnell on the east portico of the US Capitol building and requested an apology. When Grinnell refused to do so he would be struck several times by Rousseau's cane. In response Rosseau would be censured by the House of Representatives.
 * July 2, 1881: Assassination of James A. Garfield: President James A. Garfield was assassinated at 9:30   a.m. while he waited for a train at Washington's Baltimore and Potomac Railroad station on the National Mall (at the present location of the National Gallery of Art), less than four months after he took office. As the president was arriving at the train station, writer and lawyer Charles J. Guiteau shot him twice; one bullet grazed the president's shoulder, and the other pierced his back. Garfield lingered for eleven weeks before dying on September 19, 1881, at 10:35    p.m. of complications caused by infections, which were contracted by the doctors' relentless probing of his wound with unsterilized fingers and instruments. Guiteau was immediately arrested. After a highly publicized trial lasting from November 14, 1881, to January 25, 1882, he was found guilty and sentenced to death, which took place on June 30, 1882. Guiteau was assessed during his trial as mentally unbalanced, possibly due to the effects of syphilis on the brain. He claimed to have shot Garfield out of disappointment at being passed over for appointment as Ambassador to France.

 * July 28, 1932: Bonus Army Conflict: a group of 43,000 demonstrators – made up of 17,000 U.S. World War I veterans, together with their families and affiliated groups – gathered in Washington, D.C. to demand early cash redemption of their service certificates. U.S. Attorney General William D. Mitchell ordered the group to be removed from all government property. Washington police, met with resistance, shot at the protestors, and two veterans were wounded and later died. President Herbert Hoover then ordered the U.S. Army to clear the marchers' campsite. Army Chief of Staff General Douglas MacArthur commanded a contingent of infantry and cavalry, supported by six tanks.

The group cited the continued war in Vietnam and Cambodia and the continued U.S. support for those governments.
 * September 21, 1976: Assassination of Orlando Letelier: Orlando Letelier, a former member of the Chilean government, who was living in exile in the United States, was killed by a car bomb along with his assistant Ronni Moffitt.

Declassified U.S. documents revealed that Chilean army general and dictator Augusto Pinochet directly ordered the assassination.
 * March 9–11, 1977: Hanafi Siege: Three buildings in Washington, D.C. were seized by 12 "Hanafi Movement" gunmen, including the District Building (city hall), then called the John A. Wilson Building, B'nai B'rith headquarters and the Islamic Center of Washington. The siege was led by Hamaas Abdul Khaalis, who wanted to bring attention to the murder of his family in 1973 (See: January 18, 1973, above). The hostage takers held 149 people, two of whom died.

 * March 30, 1981: Attempted assassination of Ronald Reagan: President Ronald Reagan and three others were shot and wounded by John Hinckley, Jr. after a speaking engagement by Reagan at the Hilton Washington. Hinckley believed the attack would impress actress Jodie Foster, with whom he had become obsessed. White House Press Secretary James Brady, Secret Service agent Tim McCarthy, and police officer Thomas Delahanty were also wounded. All three survived, but Brady suffered brain damage and was permanently disabled. His death in 2014 was considered a homicide because it was ultimately caused by this injury.
 * December 7, 1981: A kidnapping of members of the Federal Reserve Board at the Federal Reserve headquarters building was attempted by James von Brunn, a white supremacist, neo-Nazi, and Holocaust denier. Von Brunn's motive was to raise awareness of alleged "treacherous and unconstitutional" acts by the Federal Reserve. He would later attack the United States Holocaust Memorial Museum on June 10, 2009.
 * December 8, 1982: Norman Mayer, an anti-nuclear weapons activist and eccentric, drove a white van up to the base of the Washington Monument.

Attendees included white nationalists and members of far-right groups such as the Proud Boys, as well as counter-protestors from various far-left organizations. After nightfall, violence broke out between the attendees and counter-protesters. The latter began stealing MAGA hats and flags and proceeded to light them on fire. The chaos culminated at 8:00p.m. when violence broke out five blocks east of the White House. The opposing groups charged each other, brawling for several minutes before police intervened. At least 10 were arrested and two officers were injured; one man was stabbed.
 * December 12, 2020: Supporters of President Trump hosted a "Stop the Steal" rally at the Freedom Plaza, drawing 10,000–15,000 attendees.

They were apprehended by police on October 24. Muhammad was sentenced to death and Malvo, a juvenile, was sentenced to six consecutive life sentences without parole. At the 2006 trial of Muhammad, Malvo testified that the aim of the killing spree was to kidnap children for the purpose of extorting money from the government.
 * March 1, 2007: Paul Joyal, a security analyst and critic of the administration of Russian president Vladimir Putin, was shot and wounded in front of his Adelphi, Maryland, home.

 * May 2, 2021: A man, whose name has not yet been released, attempted to enter the campus of the Langley, Virginia CIA facility after multiple prior attempts. The man, who was, by some reports, mentally ill, was stopped by armed guards, and was ordered to leave his car. He refused, and a standoff was initiated. FBI officers arrived, but a couple hours later, he exited his vehicle and claimed he had a gun, before moving erratically towards them. He was then shot by one of the FBI agents, and died the next day. The FBI is investigating the incident in order to figure out the motive of the man. The FBI later reported that, despite the man's repeated claims, he was not in fact armed.
