The historical origin of the vertical middle finger

The origin of the gesture "vertical middle finger" first appeared at the end of the Hundred Years' War between Britain and France. The British archers caused heavy losses to the French army, and the French army vowed to cut off the middle finger of the British archers after defeating the British army. But as a result, the French army was defeated. When the French army retreated, the British archers stretched out their right middle finger to show off their still existing middle finger. This insulting gesture quickly became popular in western countries.

Second, the introduction:

The middle finger shows contempt. This is a common way to insult others in the world, and it is a very impolite performance.
