World War

A world war is a war affecting most of the world's most powerful and populous countries. World wars span multiple countries on multiple continents, with battles fought in multiple theaters.

The term is usually applied to the two conflicts of unprecedented scale that occurred during the 20th century: World War I (1914–1918) and World War II (1939–1945). However, it is also sometimes applied to earlier wars and to a hypothetical future war.

Famous quotes containing the words world and/or war:

    Children belong in families, which, ideally, serve as a sanctuary and a cushion from the world at large. Parents belong to society and are a part of that greater world. Sometimes parents are a channel to the larger society, sometimes they are a shield from it. Ideally they act as filters, guiding their children and teaching them to avoid the tempting trash.
    Louise Hart (20th century)

    The dead have been awakened—shall I sleep?
    The world’s at war with tyrants—shall I crouch?
    The harvest’s ripe—and shall I pause to reap?
    I slumber not; the thorn is in my couch;
    Each day a trumpet soundeth in mine ear,
    Its echo in my heart.
    George Gordon Noel Byron (1788–1824)
