Baron Pierre de Coubertin played a significant role in establishing the International Olympic Committee (IOC) in 1894, reviving the ancient Olympic Games. His vision was to promote international unity and peace through sport, embodying the idea of Olympism which emphasizes the value of physical and moral qualities. Coubertin's efforts led to the first modern Olympics in Athens in 1896, creating a platform for athletes worldwide to compete and celebrate human achievement. His contributions laid the foundation for the Olympic movement we recognize today, fostering sportsmanship among nations and encouraging global collaboration through athletic competition.
