Through the 1920s and 1930s,

the 1914–1918 war was generally known as “TheGreatWar.”

“That was before we knew enough to number them.”

Since the mid-1940s,

the 1914–1918 war has been generally known as “WorldWarOne.”

On monuments erected before 1940, it is called “The Great War;”

on later monuments it is called “WorldWarOne.”

In newspapers published in the 1940s, 1950s, and 1960s,

you will sometimes see references to “The Kaiser War” (1914-1918)

and “The Hitler War” (1939-1945).
