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:
“No man, however benevolent, liberal, and wise, can use a large fortune so that it will do half as much good in the world as it would if it were divided into moderate sums and in the hands of workmen who had earned it by industry and frugality. The piling up of estates often does great and conspicuous good.... But no man does with accumulated wealth so much good as the same amount would do in many hands.”
—Rutherford Birchard Hayes (18221893)
“But is an enemy so execrable that tho in captivity his wishes and comforts are to be disregarded and even crossed? I think not. It is for the benefit of mankind to mitigate the horrors of war as much as possible.”
—Thomas Jefferson (17431826)
