The incident that actually ignited the French Revolution was a group of dancers at a public dance in Paris  who insisted on a left allemande, despite the caller's pleas for a right allemande--much more mundane than the incident at Fort Sumter which ignited the United States' Civil War, or the assassination of Duke Ferdinand which ignited WWI.
