A world war is an international conflict that involves most or all of the world's major powers. Conventionally, the term is reserved for the two major international conflicts that occurred during the first half of the 20th century: World War I (1914–1918) and World War II (1939–1945). Some historians have also characterized other global conflicts as world wars, such as the Cold War and the war on terror.
