In the first century BC, a slave named Spartacus threatened the might of Rome. Spartacus (c. 109 BC-71 BC) was the leader (or possibly one of several leaders) of the massive slave uprising known as the Third Servile War. Under his leadership, a tiny band of rebel gladiators grew into a huge revolutionary army, numbering about 100,000. In the end the full force of the Roman army was needed to crush the revolt.
