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.

—Franklin D. Roosevelt (1882–1945)
“Testimony of all ages forces us to admit that war is among the most dangerous enemies to liberty, and that the executive is the branch most favored by it of all the branches of Power.”
—James Madison (1751–1836)
