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:
“The world leaves no track in space, and the greatest action of man no mark in the vast idea.”
—Ralph Waldo Emerson (1803–1882)
“When they are not at war they do a little hunting, but spend most of their time in idleness, sleeping and eating. The strongest and most warlike do nothing. They vegetate, while the care of hearth and home and fields is left to the women, the old and the weak. Strange inconsistency of temperament, which makes the same men lovers of sloth and haters of tranquility.”
—Tacitus (c. 55–c. 120)
