The History of Margarine: A Hundred-Year Fight Over Fake Butter

Butter was once so scarce it started a science experiment — and the "fake butter" it produced ended up landing people in federal prison. In 1869, a French chemist was ordered to invent a cheap butter substitute for Napoleon III's army. What he created — margarine — should have been a simple wartime fix. Instead, it triggered nearly a century of legal warfare: taxed by Congress, banned outright in six states, forced by law to be dyed an unappetizing pink, and treated as contraband smuggled across state lines on so-called "oleo runs." This is the real history of margarine — the invention, the Butter Wars, the criminalization of a kitchen staple, and the small-town blindfold taste test that finally ended it.
