From the 1968 assassination of Martin Luther King Jr., to the 2008 election of Barack Obama, to widespread global protests declaring Black Lives Matter in 2020, African American history in the United States has been filled with both triumph and strife.

Here's a look at some of the notable milestones that took place from the end of the civil rights movement to today.

April 4, 1968: Civil rights leader Martin Luther King Jr. is shot and killed at the age of 38 while standing on the balcony of his Lorraine Motel room in Memphis, Tenn.

April 11, 1968: Just days after King's assassination, Johnson signs the Fair Housing Act of 1968, also called the Civil Rights Act of 1968, into law, prohibiting housing discrimination nationwide based on race, religion, national origin and sex (it was later amended to include disability and family status). The bill had languished in Congress, but King's murder prompted Johnson's urging for approval.

Aug. 29, 1968: Arthur Ashe, at age 25, becomes the first African American man to win the U.S. Open (Althea Gibson was the first woman to do so in 1958). He goes on to win the Australian Open in 1970, Wimbledon in 1975 and was ranked in the world's top 10 players for 10 years.

Serving seven terms, she was a founder of the Congressional Black Caucus and Women's Caucus, and ran for president in 1972, the first Black woman to campaign for a major party nomination.

“The next time a woman of whatever color, or a dark-skinned person of whatever sex aspires to be president, the way should be a little smoother because I helped pave it," she wrote in 1973.
