Attacks on buildings and structures in Maryland

The Dawson family, a family of seven (parents Carnell, Angela, and five children), were all murdered in Baltimore, Maryland, USA, on October 16, 2002. After Angela had repeatedly alerted police to drug dealing, assaul, and other crime in her East Baltimore neighborhood of Oliver, the entire family died after their home was firebombed. A neighbor, Darrell L. Brooks — once a page in the Baltimore City Council chamber — pled guilty to the crimes and was given a life sentence without the possibility of parole. At the time of the attack, Brooks was on probation but had been left unsupervised.

Matthew Williams was lynched on December 4, 1931 in Salisbury, Maryland. He was pulled from a bed in Peninsula General Hospital where he was being treated for a self-inflicted gunshot wound, thrown out of a window and hanged. He had been hospitalized after he shot and killed his white employer and attempted suicide.

The Hunters Brooke arson was a series of fires that destroyed over two dozen houses in the under-construction Hunters Brooke Development on Maryland Route 225, southeast of Indian Head, Maryland, in the United States, on December 6, 2004.

On September 20, 2018, four people were shot and killed outside a Rite Aid distribution center in Aberdeen, Maryland, United States. The shooting occurred 30 miles (48 km) northeast of Baltimore. This was the eighth mass shooting in Maryland in 2018, according to the Gun Violence Archive.

The raid on Catoctin Station was executed against a train passing through the Catoctin Station on the Baltimore and Ohio Railroad on June 17, 1863 by Confederate cavalry forces, during the movement north into Maryland by Gen. Robert E. Lee early in the Gettysburg Campaign. Union Army forces further west, in the city of Winchester, Virginia, had just been routed by Lt.Gen. Ewell's Second Corps on June 15 during the Second Battle of Winchester and federal troops were evacuating east to Harpers Ferry, West Virginia in a state of disarray. Rumors of an invasion by Lee created panic in the region, and no more trains departed Baltimore except for the mail train to Harpers Ferry that provided supplies to the Union forces in Frederick County, Maryland.

On June 28, 2018, a mass shooting occurred at the offices of The Capital, a newspaper serving Annapolis, Maryland, United States. The gunman, Jarrod Ramos, killed five employees with a shotgun and injured two others who were trying to escape. Ramos was arrested shortly thereafter. He pleaded guilty but not criminally responsible to 23 charges; in July 2021, a jury found him criminally responsible. It is the deadliest mass shooting in Maryland history.

The Baltimore bank riot of 1835 took place in Baltimore, the major port city of Maryland. It was a violent reaction to the failure of the Bank of Maryland in 1834. Thousands of citizens had lost millions of dollars in savings. The riot, which lasted from 6 to 9 August, attacked the homes and property of a number of former directors of the bank, who had been accused of financial misconduct and fraud, as well as the federal district courthouse located on Battle Monument Square. The Baltimore bank riot was one of the most violent and destructive events of civic unrest in any American city prior to the Civil War.
