The Olympic Games originated in ancient Greece, specifically in Olympia, around 776 BC. They were held in honor of Zeus, the king of the Greek gods. Initially, the events were limited to athletics, but over time, the games expanded to include various competitions such as wrestling, boxing, and chariot racing. They were held every four years, drawing participants from different city-states, and became a symbol of unity and peace in the region. The modern Olympic Games, revived in the late 19th century, continue to celebrate this legacy of competition and international camaraderie.
