Answer:
As an immediate reaction to Martin Luther King Jr.'s assassination in 1968, a wave of riots in different American cities took place, although the most significant riots took place in Washington DC.
Step-by-step explanation:
Martin Luther King Jr. was assassinated in Memphis, Tennessee, on April 4, 1968, just four years after the signing of the Civil Rights Act and with a country still divided by racial segregation. The African-American community in Washington DC reacted violently to the news and for three days maintained a protest that devastated part of the city.
13 people died, hundreds were injured and 7,600 were arrested. It took more than 13,000 members of the Army, the Marine Corps and the National Guard to regain control of the city.
