Lyndon B. Johnson served as the 36th President of the United States from 1963 to 1969. He assumed the office on November 22, 1963, after the assassination of President John F. Kennedy in Dallas, Texas. Johnson completed Kennedy’s term and was elected to a full term in his own right in 1964. He declined to seek reelection in 1968. This profile explains who became president after LBJ, how the transition occurred, and the constitutional and political context of the change.
The 1968 Election and the Search for a New President
By 1968, Lyndon Johnson had presided over significant domestic achievements, including the Civil Rights Act of 1964 and the Voting Rights Act of 1965, but also an increasingly unpopular war in Vietnam. On March 31, 1968, Johnson announced he would not seek reelection, opening the Democratic nomination to a crowded field that included Vice President Hubert Humphrey, Senator Eugene McCarthy, and Senator Robert F. Kennedy.
Democratic Primaries and a Divided Party
The Democratic primaries and caucuses reflected deep divisions over the Vietnam War and civil rights. McCarthy’s strong showing in New Hampshire and Kennedy’s entry into the race shifted momentum, but the party establishment ultimately coalesced around Humphrey, who secured the nomination at the tumultuous 1968 Democratic National Convention in Chicago. Meanwhile, the Republican Party nominated Richard Nixon, who ran on a platform of restoring law and order and ending the war with “Vietnamization.” The election thus presented a choice between Humphrey, closely tied to the Johnson administration, and Nixon, promising a new approach to Vietnam and domestic stability.
Richard Nixon: The President After LBJ
Richard Nixon won the 1968 general election, becoming the 37th President of the United States on January 20, 1969. He received 301 electoral votes to Humphrey’s 191, with third-party candidate George Wallace winning 46 electoral votes and several million popular votes. The outcome reflected voter fatigue with the war, concerns about social unrest, and Nixon’s promise of a “secret plan” to end Vietnam hostilities. At noon on January 20, 1969, the presidential oath was administered by Chief Justice Earl Warren, marking the formal transition of executive power from the Johnson administration to Nixon’s presidency.
Formal Transition Details
- November 5, 1968: General election; Nixon wins 301 electoral votes.
- January 20, 1969: Inauguration Day; Nixon sworn in as 37th president.
- January 20, 1969, 12:00 p.m.: Presidential transition effective; LBJ leaves office.
Constitutional Mechanisms for Presidential Succession
The process by which Nixon succeeded Johnson illustrates both an election-driven transfer and the constitutional framework for presidential transitions. The Twentieth Amendment sets the start date for presidential terms at January 20 following a general election. The Presidential Succession Act of 1947 establishes the line of succession should the office become vacant between elections, but in 1969 the mechanism was straightforward: the winner of the November election was inaugurated on January 20, ensuring continuity of government.
Key Figures in the Transition
Several key figures shaped the transition from Johnson to Nixon. Vice President Hubert Humphrey represented continuity with Johnson’s policies, particularly on civil rights and Vietnam, while Nixon’s staff, including White House Chief of Designate H. R. Haldeman and domestic policy advisor John Ehrlichman, began informal transition planning well before the election results were finalized. The General Services Administration (GSA) played a crucial logistical role in facilitating the transfer of presidential power, providing office space, security clearances, and operational briefings to the president-elect’s team.

| Gerald Ford | Nelson Rockefeller | August 9, 1974 | January 20, 1977 | Appointment and Election |
Legacy and Historical Context
The Johnson-to-Nixon transition coincided with profound cultural and geopolitical shifts in the United States. Domestically, the federal government’s role in civil rights enforcement expanded, while debates over federal power and states’ rights intensified. Internationally, the Vietnam War continued until the Paris Peace Accords in 1973, and the Nixon administration pursued détente with the Soviet Union and the opening of relations with China. Understanding who became president after LBJ thus provides a useful lens for examining this pivotal period in American politics.
