The country that is considered the origin of the Olympic Games is Greece. The ancient Olympic Games began in Olympia, Greece, in 776 BC and were held in honor of the god Zeus. Initially, the games featured only a single event, the foot race, but they gradually expanded to include various athletic competitions, including wrestling, boxing, and chariot racing. The Olympics were a significant cultural and religious festival in ancient Greece, promoting unity amongst the city-states. The modern Olympic Games, revived in 1896, have continued this tradition, celebrating sports and international cooperation, while maintaining Greece's legacy in athletic achievement.
