Oklahoma City Bombing

At 9:02 a.m. on April 19, 1995, a truck bomb packed with 4,800 pounds of ammonium nitrate fertilizer detonated outside the Alfred P. Murrah Federal Building in Oklahoma City, Oklahoma. The blast destroyed the north face of the nine-story structure, killed 168 people — including 19 children in the building's day care center — and injured nearly 700 more. It was, until September 11, 2001, the deadliest act of terrorism on American soil. The perpetrator was not a foreign adversary but a decorated U.S. Army veteran named Timothy McVeigh.

McVeigh had chosen both the target and the date deliberately. April 19 was the second anniversary of the FBI's final assault on the Branch Davidian compound in Waco, Texas, and also the 220th anniversary of the 1775 Battles of Lexington and Concord — a date that carried deep symbolic weight in the far-right militia movement McVeigh inhabited. He believed the federal government had become a tyrannical occupying force and that violent resistance was both justified and necessary. He was arrested within hours, tried, convicted on all charges, and executed by lethal injection in June 2001.

The bombing forced a national reckoning with the scope and radicalization of the American militia movement — a network of anti-government organizations that had grown rapidly in the early 1990s and that law enforcement had substantially underestimated. The image of firefighter Chris Fields carrying one-year-old Baylee Almon from the wreckage became one of the decade's defining photographs. The Oklahoma City National Memorial, opened in 2000, arranges 168 empty bronze chairs in nine rows — one for each floor of the building — on the precise footprint of the Murrah's north face.
