John F. Kennedy was the 35th President of the United States, serving from January 20, 1961, until his assassination on November 22, 1963. A Democrat and former U.S. senator from Massachusetts, he is remembered for his Cold War leadership and ambitious domestic and space initiatives.
Kennedy's presidency was defined by Cold War confrontations and high-stakes diplomacy. He navigated crises such as the Bay of Pigs invasion and the Cuban Missile Crisis, pursued arms-control agreements like the 1963 Partial Nuclear Test Ban Treaty, and worked to maintain U.S. credibility abroad.
On the domestic front, Kennedy advanced a program called the New Frontier that promoted economic stimulus, education, and social programs, established the Peace Corps, and used federal authority to press for civil rights. His pledge to land a man on the Moon and his assassination in 1963 left a lasting cultural and political legacy.
