Barry Farm is a neighborhood in Southeast Washington, D.C., located east of the Anacostia River and bounded by the Southeast Freeway to the northwest, Suitland Parkway to the northeast and east, and St. Elizabeths Hospital to the south. The neighborhood was renowned as a significant post-Civil-War settlement of free Blacks and freed slaves established by the Freedmen's Bureau. The streets were named to commemorate the Union generals, Radical Republicans, and Freedmen's Bureau officials who advanced the rights of Black Americans during the Civil War and Reconstruction: Howard Road SE for General Oliver O. Howard; Sumner Road SE for Massachusetts Senator Charles Sumner; Wade Road SE for Ohio Senator Benjamin Wade; Pomeroy Road SE for Kansas Senator Samuel C. Pomeroy; Stevens Road SE for Pennsylvania Congressman Thaddeus Stevens, and Nichols Avenue (now Martin Luther King Jr. Avenue SE) for Henry Nichols who was the first superintendent of Saint Elizabeth's Hospital (Formerly called the Government Insane Asylum). The neighborhood name is not a reference to the late former mayor of Washington, D.C., Marion Barry, but coincidentally has the same spelling.

It opened in 1855 under the name Government Hospital for the Insane, the first federally operated psychiatric hospital in the United States.

The Bonus Army was a group of 43,000 demonstrators – 17,000 veterans of U.S. involvement in World War I, their families, and affiliated groups – who gathered in Washington, D.C., in mid-1932 to demand early cash redemption of their service bonus certificates. Organizers called the demonstrators the Bonus Expeditionary Force (B.E.F.), to echo the name of World War I's American Expeditionary Forces, while the media referred to them as the "Bonus Army" or "Bonus Marchers". The demonstrators were led by Walter W. Waters, a former sergeant. Many of the war veterans had been out of work since the beginning of the Great Depression. The World War Adjusted Compensation Act of 1924 had awarded them bonuses in the form of certificates they could not redeem until 1945. Each certificate, issued to a qualified veteran soldier, bore a face value equal to the soldier's promised payment with compound interest. The principal demand of the Bonus Army was the immediate cash payment of their certificates. On July 28, 1932, U.S. Attorney General William D. Mitchell ordered the veterans 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 Bonus Army marchers with their wives and children were driven out, and their shelters and belongings burned. A second, smaller Bonus March in 1933 at the start of the Roosevelt administration was defused in May with an offer of jobs with the Civilian Conservation Corps (CCC) at Fort Hunt, Virginia, which most of the group accepted. Those who chose not to work for the CCC by the May 22 deadline were given transportation home. In 1936, Congress overrode President Roosevelt's veto and paid the veterans their bonus nine years early.
