In what year did John F. Kennedy become president?

John F. Kennedy became president in 1961 after winning the presidential election in November 1960. He was inaugurated on January 20, 1961, marking the start of his presidency. This event is significant in American history as it represented a generational change in leadership, with Kennedy being the youngest elected president at the time.

In understanding the context of the other options, while the election took place in 1960, it was not until the following January that Kennedy officially took office. The year 1963 is notable for Kennedy’s assassination, and 1964 is associated with Lyndon B. Johnson’s presidency, which began after Kennedy’s death. Therefore, 1961 is the correct year marking when Kennedy assumed the role of President of the United States.
