Lyndon B. Johnson played a significant role in Black history during his presidency from 1963 to 1969. Johnson was a key figure in advancing the civil rights movement, particularly with the passage of the Civil Rights Act of 1964 and the Voting Rights Act of 1965.

The Civil Rights Act of 1964 outlawed discrimination based on race, color, religion, sex, or national origin and ended segregation in public places. It was a landmark piece of legislation that marked a major step forward in the struggle for civil rights for African Americans.

Johnson also signed the Voting Rights Act of 1965 into law, which aimed to overcome legal barriers that prevented African Americans from exercising their right to vote. The act prohibited discriminatory voting practices such as literacy tests and poll taxes, which had been used to disenfranchise Black voters.

Overall, Johnson's support for civil rights legislation and his efforts to combat racial discrimination had a profound impact on Black history and helped to advance the cause of equality and justice for African Americans in the United States.
