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.

A slave rebellion is an armed uprising by slaves, as a way of fighting for their freedom. Rebellions of slaves have occurred in nearly all societies that practice slavery or have practiced slavery in the past. A desire for freedom and the dream of successful rebellion is often the greatest object of song, art, and culture amongst the enslaved population. These events, however, are often violently opposed and suppressed by slaveholders.
