Lyndon Baines Johnson (August 27, 1908 – January 22, 1973), often referred to as LBJ, was the 36th President of the United States (1963–1969) after his service as the 37th Vice President of the United States (1961–1963). He is one of only four people who served in all four elected federal offices of the United States: Representative, Senator, Vice President and President.
Johnson, a Democrat, served as a United States Representative from Texas, from 1937–1949 and as United States Senator from 1949–1961, including six years as United States Senate Majority Leader, two as Senate Minority Leader and two as Senate Majority Whip. After campaigning unsuccessfully for the Democratic nomination in 1960, Johnson was asked by John F. Kennedy to be his running mate for the 1960 presidential election.
Johnson succeeded to the presidency following the assassination of John F. Kennedy, completed Kennedy's term and was elected President in his own right, winning by a large margin in the 1964 Presidential election. Johnson was greatly supported by the Democratic Party and, as President, was responsible for designing the "Great Society" legislation that included laws that upheld civil rights, Public Broadcasting, Medicare, Medicaid, environmental protection, aid to education, and his "War on Poverty." He was renowned for his domineering personality and the "Johnson treatment," his coercion of powerful politicians in order to advance legislation.
