Lyndon B. Johnson, a Democrat from Texas, became president after John F. Kennedy's assassination in 1963 and served until 1969. He pursued an ambitious domestic agenda while presiding over a major escalation of the Vietnam War.
Johnson’s domestic agenda, known as the Great Society, expanded civil rights, health care, education, and anti-poverty programs, producing landmark laws such as the Civil Rights Act, the Voting Rights Act, Medicare, and Medicaid.
His decision to escalate U.S. military involvement in Vietnam eroded public support and overshadowed many of his achievements, leaving a complex legacy that reshaped civil rights, social policy, and debates over U.S. foreign intervention.
