The Olympic Games are the world's foremost sports competition held every four years, with Summer and Winter Games alternating. Over 200 nations participate in competitions inspired by the ancient Olympic Games in Greece. The International Olympic Committee was founded in 1896 to oversee the modern Olympics. Winners receive medals while the ancient Greeks awarded olive leaf crowns. Key Olympic symbols include the rings, motto "Faster, Higher, Stronger", creed of participation over victory, and lighting the Olympic flame.
