Liberty cabbage (also known as victory cabbage) was an American euphemism for "sauerkraut." It was introuced in the United States during World War I, but was rarely used thereafter. During the same period "liberty steak" was used in place of "hamburger" (hamburger is derived from "Hamburg", a city in Germany); this euphemism regained popular usage during World War II. Other euphemisms to spring up during the second World War include "liberty measles" for "German measles," "Eisenhower jacket" for "Hindenburg jacket," "Eisenhower herring" for "Bismarck herring, and others.
