Final answer:
Robert Kennedy was assassinated at the Ambassador Hotel in Los Angeles on June 5, 1968, by Sirhan Sirhan after a significant victory in the California Democratic primary. Kennedy's death was a major setback to the Civil Rights Movement and left the nation in mourning.
Step-by-step explanation:
Robert F. Kennedy was assassinated in Los Angeles at the Ambassador Hotel on June 5, 1968, shortly after winning the California Democratic primary. Kennedy, who was a former U.S. Attorney General and a U.S. Senator from New York, was a passionate advocate for civil rights and had been instrumental in advancing the Civil Rights Act of 1964. His assassination by Sirhan Sirhan, a Jordanian immigrant, was a devastating blow to many Americans who saw Kennedy as a unifying force capable of progressing civil rights in a turbulent era.
On the fateful night, after delivering his victory speech, Kennedy was shot as he tried to exit the hotel through the kitchen; he died 26 hours later. Sirhan's motive was reportedly Kennedy's support for Israel during the Arab-Israeli conflict. The loss of Robert Kennedy marked a tragic end to a hopeful campaign and heightened the tumult of 1968, a year already burdened by deep societal and political divisions.
