Racist bombings in Birmingham, Alabama disrupt nonviolence in the Birmingham campaign and precipitate a crisis involving federal troops.

The Birmingham riot of 1963 was a civil disorder and riot in Birmingham, Alabama, that was provoked by bombings on the night of May 11, 1963. The bombings targeted African-American leaders of the Birmingham campaign, but ended in the murder of three adolescent girls. The places bombed were the parsonage of Rev. A. D. King, brother of Martin Luther King Jr., and a motel owned by A. G. Gaston, where King and others organizing the campaign had stayed. It is believed that the bombings were carried out by members of the Ku Klux Klan, in cooperation with Birmingham police. In response, local African-Americans burned businesses and fought police throughout the downtown area.

Civil rights protesters were frustrated with local police complicity with the perpetrators of the bombings, and grew frustrated at the non-violence strategy directed by King. Initially starting as a protest, violence escalated following local police intervention. The federal government intervened with federal troops for the first time to control violence during a largely African-American riot. It was also a rare instance of domestic military deployment independent of enforcing a court injunction, an action which was considered controversial by Governor George Wallace and other Alabama whites. The African-American response was a pivotal event that contributed to President Kennedy's decision to propose a major civil rights bill. It was ultimately passed under President Lyndon B. Johnson as the Civil Rights Act of 1964.

Birmingham ( BUR-ming-ham) is a city in the north central region of the U.S. state of Alabama. Birmingham is the seat of Jefferson County, Alabama's most populous county. As of 2020, Birmingham had a population of 200,733, making it Alabama's second-most populous city after Huntsville. The broader Birmingham metropolitan area had a 2020 population of 1,115,289, and is the largest metropolitan area in Alabama as well as the 50th-most populous in the United States. Birmingham serves as an important regional hub and is associated with the Deep South, Piedmont, and Appalachian regions of the nation.

Birmingham was founded in 1871, during the post-Civil War Reconstruction period, through the merger of three pre-existing farm towns, notably, former Elyton. It grew from there, annexing many more of its smaller neighbors, into an industrial and railroad transportation center with a focus on mining, the iron and steel industry, and railroading. Birmingham was named for Birmingham, England; one of that nation's major industrial cities. Most of the original settlers who founded Birmingham were of English ancestry. The city may have been planned as a place where cheap, non-unionized, and often African-American labor from rural Alabama could be employed in the city's steel mills and blast furnaces, giving it a competitive advantage over industrial cities in the Midwest and Northeast.From its founding through the end of the 1960s, Birmingham was a primary industrial center of the South. The pace of Birmingham's growth during the period from 1881 through 1920 earned its nicknames The Magic City and The Pittsburgh of the South. Much like Pittsburgh, Birmingham's major industries were iron and steel production, plus a major component of the railroading industry, where rails and railroad cars were both manufactured in Birmingham. In the field of railroading, the two primary hubs of railroading in the Deep South were nearby Atlanta and Birmingham, beginning in the 1860s and continuing through to the present day. The economy diversified during the later half of the twentieth century. Though the manufacturing industry maintains a strong presence in Birmingham, other businesses and industries such as banking, telecommunications, transportation, electrical power transmission, medical care, college education, and insurance have risen in stature. Mining in the Birmingham area is no longer a major industry with the exception of coal mining. Birmingham ranks as one of the most important business centers in the Southeastern United States and is also one of the largest banking centers in the United States. In addition, the Birmingham area serves as headquarters to one Fortune 500 company: Regions Financial, along with five other Fortune 1000 companies.

In higher education, Birmingham has been the location of the University of Alabama School of Medicine (formerly the Medical College of Alabama) and the University of Alabama School of Dentistry since 1947. Since that time it has also obtained a campus of the University of Alabama, University of Alabama at Birmingham (founded circa 1969), one of three main campuses of the University of Alabama System. It is also home to three private institutions: Samford University, Birmingham-Southern College, and Miles College. Between these colleges and universities, the Birmingham area has major colleges of medicine, dentistry, optometry, pharmacy, law, engineering, and nursing. Birmingham is also the headquarters of the Southeastern Conference, one of the major U.S. collegiate athletic conferences.
