Henry Cabot Lodge Jr. in the context of "1960 Democratic National Convention"

The 1960 presidential campaign of John F. Kennedy, then junior United States senator from Massachusetts, was formally launched on January 2, 1960, as Senator Kennedy announced his intention to seek the Democratic Party nomination for the presidency of the United States in the 1960 presidential election.

Kennedy was nominated by the Democratic Party at the national convention on July 15, 1960, and he named Senator Lyndon B. Johnson as his vice-presidential running mate. On November 8, 1960, they defeated incumbent Vice President Richard Nixon and United Nations Ambassador Henry Cabot Lodge Jr. in the general election. Kennedy was sworn in as president on January 20, 1961, and would serve until his assassination on November 22, 1963. His brothers Robert and Ted would both later run for president in 1968 and 1980 respectively, but neither received the presidential nomination.

Presidential elections were held in the United States on November 8, 1960. The Democratic ticket of Senator John F. Kennedy and his running mate, Senate Majority Leader Lyndon B. Johnson, narrowly defeated the Republican ticket of incumbent Vice President Richard Nixon and his running mate, U.N. Ambassador Henry Cabot Lodge Jr. This was the first election in which 50 states participated, marking the first participation of Alaska and Hawaii, and the last in which the District of Columbia did not. It was also the first election in which an incumbent president—in this case, Dwight D. Eisenhower—was ineligible to run for a third term because of the term limits established by the 22nd Amendment.

Nixon faced little opposition in the Republican race to succeed popular incumbent Eisenhower. Kennedy, the junior senator from Massachusetts, established himself as the Democratic frontrunner with his strong performance in the 1960 Democratic primaries, including key victories in Wisconsin and West Virginia over Senator Hubert Humphrey. He defeated Senate Majority Leader Lyndon B. Johnson on the first presidential ballot of the 1960 Democratic National Convention, and asked Johnson to serve as his running mate.

On November 1, 1963, President Ngô Đình Diệm and the Personalist Labor Revolutionary Party of the Republic of Vietnam (South Vietnam) were deposed by a group of CIA-backed Army of the Republic of Vietnam officers who disagreed with Diệm's handling of the Buddhist crisis and the North Vietnamese and Viet Cong (VC) threat to South Vietnam. During South Vietnam's later years, some referred to the coup as Cách mạng 1-11-1963 (1st November 1963 Revolution).

The Kennedy administration had been aware of the coup planning, but Cable 243 from the United States Department of State to U.S. Ambassador to South Vietnam Henry Cabot Lodge Jr. stated that it was U.S. policy not to try to stop it. Lucien Conein, the Central Intelligence Agency's liaison between the U.S. Embassy and the coup planners, told them that the U.S. would not intervene to stop it. Conein also provided 3 million Vietnamese piastres (approx. $42,000 USD) to reward military units that joined the coup.The decision to support the coup stemmed from the Kennedy administration's growing conviction that Diem was incapable of uniting the South Vietnamese people against communism. Diem's government was also increasingly seen as repressive, particularly after his violent crackdown on Buddhist protests.

The 1960 Republican National Convention was held in Chicago, Illinois, from July 25 to July 28, 1960, at the International Amphitheatre. It was the 14th and most recent time overall that Chicago hosted the Republican National Convention, more times than any other city.

The convention nominated then Vice President of the United States Richard Nixon for President of the United States and former Senator Henry Cabot Lodge Jr. of Massachusetts for vice president.
