A world war is an international conflict in which most or all of the major powers of the world are involved. Although historians have also referred to other global conflicts, such as the Seven Years' War and the Cold War, as world wars, the term is traditionally reserved for two major international conflicts that took place during the first half of the 20th century, World War I (1914–1918) and World War II (1939–1945).
