President Donald Trump’s deployment of the National Guard to Los Angeles to stop protests against his immigration crackdown isn’t the first time an elected U.S. official has sent troops to thwart unrest over civil rights.
But National Guard troops are typically deployed — for a variety of emergencies and natural disasters — with the permission of governors in responding states. Trump, a Republican, sent about 1,000 California National Guard troops to Los Angeles despite the objections of California Gov. Gavin Newsom and Los Angeles Mayor Karen Bass, both Democrats.

Confrontations began Friday when dozens of protesters gathered outside a federal detention center demanding the release of more than 40 people arrested by federal immigration authorities across Los Angeles, as part of Trump’s mass deportation campaign.
Trump said that federalizing the troops on Saturday was necessary to “address the lawlessness” in California. Newsom said Trump’s order was a “complete overreaction," used to “purposely inflammatory and will only escalate tensions."

Some previous National Guard deployments have restored peace after violent crackdowns from local law enforcement or vigilante violence, but sometimes troops have intensified tensions in communities and with people who were protesting for civil rights or racial equality.
On rare occasion, presidents have invoked an 18th-century wartime law called the Insurrection Act, which is the main legal mechanism that a president can use to activate the military or National Guard during times of rebellion or unrest. Other times they have relied on a similar federal law that allows the president to federalize National Guard troops under certain circumstances, which is what Trump did on Saturday.
Still, some experts told The Associated Press that the current standoff in Los Angeles is not comparable, from a legal perspective, to past situations.
“I think that the provision that Trump is using is really an exception to the norm," said Bernadette Meyler, a professor of constitutional law at Stanford University.
Here is a look at some of the most notable deployments:
George Floyd protests in Los Angeles in 2020

Almost five years ago, Newsom deployed approximately 8,000 National Guard troops to quell protests over racial injustice inspired by the death of George Floyd in Minnesota. Well over half the troops deployed in California were sent to Los Angeles County, where police arrested more than 3,000 people. City officials at the time, including then-Los Angeles Mayor Eric Garcetti, supported Newsom's decision.
Yale historian Elizabeth Hinton, who wrote a book about race-related uprisings and police violence, said the 2020 protests were characterized as violent but for the most part were not.
That’s even truer today, she said.
“There is no imminent threat that would require the mass deployment of militarized troops,” said Hinton.
Rodney King protests in 1992

Some have compared Trump's decision on Saturday to George H.W. Bush's use of the Insurrection Act to respond to riots in Los Angeles in 1992, after the acquittal of white police officers who were videotaped beating Black motorist Rodney King. In just six days the protests became one of the deadliest race riots in American history, with 63 people dying, nine of whom were killed by police.
Syreeta Danley, a teacher from South Central Los Angeles, said she vividly remembers as a teen seeing black smoke from her porch during the 1992 uprisings.
She said some people in her neighborhood were still more afraid of the police than the National Guard because once the troops left, local police “had the green light to continue brutalizing people."
The National Guard can enforce curfews like they did in 1992, but that won’t stop people from showing up to protest, Danley said.
“I have lived long enough to know that people will push back, and I’m here for it,” Danley said.
Watts protests in 1965
There were deadly protests in the Watts neighborhood of Los Angeles in 1965 in response to pent-up anger over an abusive police force and lack of resources for the community. Over 30 people were killed — two-thirds of whom were shot by police or National Guard troops. Many say the neighborhood has never fully recovered from fires that leveled hundreds of buildings.
Breeze McDonald, a doctoral student and local school district employee from South Central Los Angeles, says she is still haunted by scars her aunt sustained after she was hosed down during the 1965 protests, and her own memories of the 1992 uprisings.
“A lot of the anger happened because our voices weren’t being heard. Because instead of stopping to listen, you decided to employ the National Guard," McDonald said.
Integration protests in the 1950-1960s

In 1956, the governor of Tennessee assigned National Guard troops to help enforce integration in Clinton, Tennessee, after white supremacists violently resisted federal orders to desegregate.
President Dwight Eisenhower called the Arkansas National Guard and the 101st Airborne Division of the U.S. Army in 1957 to escort nine Black students as they integrated a previously white-only school.
A few years later, the Maryland National Guard remained in the small town of Cambridge for two years after Maryland’s Democratic Gov. J Millard Tawes in 1963 called in troops to mediate violent clashes between white mobs and Black protesters demanding desegregation.
Selma, Alabama, voting rights protest in 1965
National Guard troops played a pivotal role in the march often credited with pressuring the passage of Voting Rights Act of 1965, when nonviolent protesters — including the late congressman John Lewis — calling for the right to vote were brutally assaulted by Alabama State Troopers in Selma, Alabama, in 1965.
Two weeks later, then-President Lyndon B. Johnson sent National Guard troops to escort thousands of protesters along the 50-mile march to the state Capitol. Johnson's decision was at odds with then-Gov. George Wallace who staunchly supported segregation.
