The Olympic Games first began as athletic festivals to honor the Greek gods. At that time, the most important festival was held in the valley of Olympia to honor Zeus, the king of the gods. It was the festival that became the Olympic games in 776 B.C. Later, these Games were ended in A.D. 394 by the Roman Emperor who ruled Greece. No Olympic Games were held for more than 1,500 years. Then the modern Olympics began in 1896. Almost 300 male athletes competed in the first modern Olympics. During the games held in 1900, female athletes were allowed to compete. The games have continued every four years since 1896 except during World War II, and they will most likely continue for many years to come.
