The two "world wars" are called that because they were major wars that involved most countries in the world, and were fought all over the world. World War I was fought in Europe, Africa, the Middle East, the Atlantic Ocean, and even in the Pacific and China.
World War II involved even more, and took place in Europe, Africa, Asia/Pacific, even a little bit in North and South America!
