From Rodney King riots to LA today: When presidents have deployed troops inside the US

Federal troops in American cities have historical precedent, from President George H.W. Bush's response to Rodney King riots to President Dwight D. Eisenhower protecting Little Rock, Arkansas, students during desegregation.

After a jury acquitted four LAPD officers in the brutal beating of Rodney King, riots erupted across Los Angeles. The chaos prompted then-California Gov. Pete Wilson to request federal assistance.

Then-President George H.W. Bush invoked the Insurrection Act, deploying 4,000 U.S. Army soldiers and 1,500 Marines in addition to National Guardsmen. The riots left more than 60 people dead, thousands injured and large swaths of the city burned.

Bush condemned the violence in a televised address.

"What followed Wednesday's jury verdict in the Rodney King case was a tragic series of events… nearly 4,000 fires, staggering property damage, hundreds of injuries, and the senseless deaths of over 30 people."

A notable incident underscored the challenges of military-civilian coordination. During a tense exchange, a police officer reportedly yelled "Cover me!" to nearby Marines, asking them to watch his back during a domestic disturbance response. Trained in combat response, they misunderstood the command and fired over 200 rounds into a house, believing they were providing covering fire, according to an article printed in an Army War College publication.

One of the most violent civil disturbances in U.S. history broke out after a police raid on an unlicensed bar in Detroit. The five-day riot left 43 dead, more than 1,000 injured and 400 buildings destroyed.

Then-Michigan Gov. George Romney called in 8,000 National Guardsmen. Johnson followed by deploying 4,700 federal troops from the 82nd and 101st Airborne Divisions to support overwhelmed local forces.

During the Civil War, the Union’s first draft law allowed wealthy men to pay $300 to avoid military service—sparking resentment among working-class Irish immigrants.

The protests quickly descended into four days of racially charged riots, with mobs targeting Black Americans and overwhelming local police. Then-President Abraham Lincoln redirected battle-hardened Union troops from Gettysburg, Pennsylvania, to quell the violence.
