The famous American patriotic song “Yankee Doodle” actually began as an English song of derision against the colonists.
At the time there was a Macaroni Club in London which catered to foppish, wealthy young men who copied everything Italian, including sticking a feather in their caps, which to many became the sign of a “sissy.”
When the Americans began winning the war they took possession of the song “Yankee Doodle” as revenge.
