The Third Servile War, also called the Gladiator War and the War of Spartacus by Plutarch, was the last in a series of slave rebellions against the Roman Republic known as the Servile Wars. This third rebellion was the only one that directly threatened the Roman heartland of Italy. It was particularly alarming to Rome because its military seemed powerless to suppress it.
The revolt began in 73 BC, with the escape of around 70 slave gladiators from a gladiator school in Capua. They easily defeated the small Roman force sent to recapture them, and within two years, they had been joined by some 120,000 men, women, and children. The able-bodied adults of this large group were a surprisingly effective armed force that repeatedly showed they could withstand or defeat the Roman military, from the local Campanian patrols to the Roman militia and even to trained Roman legions under consular command. This army of slaves roamed across Italy, raiding estates and towns with relative impunity, sometimes dividing into separate but connected bands with several leaders, including the famous former gladiator Spartacus.
