During the nineteen sixties in the USA, numerous citizens participated in demonstrations, fighting for their rights. Social subordination of the African-Americans and women caused escalations, while a major economic crisis had an additional impact on social division and overall feeling of apprehension. Arrival of the young and ambitious president - John Fitzgerald Kennedy - offered a glimmer of hope for civic and social equality. Due to his frequent health issues, he learned to appreciate and respect the fight for life. Upon taking the office of president, Kennedy promised to implement structural reforms, and he promised a new chapter in the history of the USA and the Americans. He started to implement democratic principles since his first arrival to the White House by proposing acts to enforce civil rights, combat organized crime, prevent juvenile delinquency, as well as by proposing acts on equal pay and the right to vote. Implementation of reforms of the justice system and of the Supreme Court enabled protection of the fundamental human rights and freedoms. He showed solidarity and generosity by founding charity organizations and helping poor third world countries. JFK managed to defeat the communist regime in Cuba and Vietnam thanks to peaceful and determined course of action. Owing to his brief yet efficient mandate, John Fitzgerald Kennedy left a great legacy to the Americans and to the rest of the world. A research was conducted and all the relevant data was incorporated in this paper upon detailed analysis of the official journals, books and specialized literature.
