He led the Gauls in 52 BC against the Roman army in Gaul led by Julius Caesar. Vercingetorix's name in Gaulish means "over-king of the marching men"; the "marching men" would now be called "infantry".
Vercingetorix was probably one of the first to unite some tribes of Gaul against a common enemy. This was the last major uprising of the peoples of Gaul against the Roman invaders.
After the celebration of Caesar's triumph was over, Vercingetorix was executed.
