Lyndon B. Johnson was the 36th President of the United States. John F. Kennedy asked him to be his running mate for the 1960 presidential election. Johnson succeeded to the presidency following the assassination of JFK in 1963 and was elected President in 1964. He was responsible for Great Society social reforms designed to eliminate poverty and racial injustice. Johnson also escalated U.S. involvement in the Vietnam War, which stimulated a large antiwar movement.
