The Peace Corps is an independent agency and program of the United States government that trains and deploys volunteers to provide international development assistance. It was established in March 1961 by an executive order of President John F. Kennedy and authorized by Congress the following September by the Peace Corps Act.Kennedy first publicly proposed the Peace Corps during his 1960 presidential campaign as a means to improve America's global image and leadership in the Cold War; he cited the Soviet Union's deployment of skilled citizens "abroad in the service of world communism" and argued the U.S. must do the same to advance values such as democracy and liberty. The Peace Corps was formally established within three months of Kennedy's presidency, garnering both bipartisan congressional support and popular support, particularly among recent university graduates.The official goal of the Peace Corps is to assist developing countries by providing skilled workers in fields such as education, health, entrepreneurship, women's empowerment, and community development. Volunteers are American citizens, typically with a college degree, who are assigned to specific projects in certain countries based on their qualifications and experience; they often work with other stakeholders, governments, schools, non-profit organizations, non-governmental organizations, and entrepreneurs. Following three months of technical training, Peace Corps members are expected to serve at least two years in the host country, after which they may request an extension of service. Volunteers are strongly encouraged to respect local customs, learn the prevailing language, and live in comparable conditions.In addition to its technical mission, the Peace Corps is intended to promote mutual understanding between Americans and foreign peoples, and by extension improve the international standing of the U.S.In its inaugural year, the Peace Corps had 900 volunteers serving 16 countries, reaching its peak in 1966 with 15,556 volunteers in 52 countries. Following budget cuts in 1989, the number of volunteers declined to 5,100, though subsequent increases in funding led to renewed growth into the 21st century; by its 50th anniversary in 2011, there were over 8,500 volunteers serving in 77 countries. Since its inception, more than 240,000 Americans have joined the Peace Corps and served in 142 countries.

John Fitzgerald Kennedy (May 29, 1917 – November 22, 1963), often referred to by his initials JFK, was an American politician who served as the 35th president of the United States from 1961 until his assassination near the end of his third year in office. Kennedy served at the height of the Cold War, and the majority of his work as president concerned relations with the Soviet Union and Cuba. A Democrat, he represented Massachusetts in both houses of the U.S. Congress prior to his presidency.

Born into the prominent Kennedy family in Brookline, Massachusetts, Kennedy graduated from Harvard University in 1940 before joining the U.S. Naval Reserve the following year. During World War II, he commanded a series of PT boats in the Pacific theater. Kennedy's survival of the sinking of PT-109 and rescue of his fellow sailors made him a war hero for which he earned the Navy and Marine Corps Medal, but left him with serious injuries. After a brief stint in journalism, Kennedy represented a working-class Boston district in the U.S. House of Representatives from 1947 to 1953. He was subsequently elected to the U.S. Senate and served as the junior senator for Massachusetts from 1953 to 1960. While in the Senate, Kennedy published his book, Profiles in Courage, which won a Pulitzer Prize. In the 1960 presidential election, he narrowly defeated Republican opponent Richard Nixon, who was the incumbent vice president. Kennedy's humor, charm, and youth in addition to his father's money and contacts were great assets in his campaign. Kennedy's campaign gained momentum after the first televised presidential debates in American history. He was the first Catholic elected president.

Kennedy's administration included high tensions with communist states in the Cold War. As a result, he increased the number of American military advisers in South Vietnam. The Strategic Hamlet Program began in Vietnam during his presidency. In April 1961, he authorized an attempt to overthrow the Cuban government of Fidel Castro in the failed Bay of Pigs Invasion. Kennedy authorized the Cuban Project in November 1961. He rejected Operation Northwoods (plans for false flag attacks to gain approval for a war against Cuba) in March 1962. However, his administration continued to plan for an invasion of Cuba in the summer of 1962. The following October, US spy planes discovered Soviet missile bases had been deployed in Cuba; the resulting period of tensions, termed the Cuban Missile Crisis, nearly resulted in the breakout of a global thermonuclear conflict. He also signed the first nuclear weapons treaty in October 1963. Kennedy presided over the establishment of the Peace Corps, Alliance for Progress with Latin America, and the continuation of the Apollo program with the goal of landing a man on the Moon before 1970. He also supported the civil rights movement, but was only somewhat successful in passing his New Frontier domestic policies.

On November 22, 1963, he was assassinated in Dallas. Vice President Lyndon B. Johnson assumed the presidency upon Kennedy's death. Marxist and former U.S. Marine Lee Harvey Oswald was arrested for the assassination, but he was shot and killed by Jack Ruby two days later. The FBI and the Warren Commission both concluded Oswald had acted alone. After Kennedy's death, Congress enacted many of his proposals, including the Civil Rights Act and the Revenue Act of 1964. Despite his truncated presidency, Kennedy ranks highly in polls of U.S. presidents with historians and the general public. His personal life has also been the focus of considerable sustained interest following public revelations in the 1970s of his chronic health ailments and extramarital affairs. Kennedy is the most recent U.S. president to have been assassinated as well as the most recent U.S. president to die in office.
