At its height between 73 and 71 BCE, the slave revolt led by Spartacus spread across large parts of southern and central Italy, threatening Roman control through rapid movement rather than territorial administration. The rebellion began in Capua and expanded through Campania, Lucania, and Apulia, with forces maneuvering across the Italian peninsula. Unlike organized states, the revolt had no fixed borders, relying instead on mobility, captured resources, and the temporary control of key routes. At its peak, it represented the most serious internal uprising against Roman authority during the Republic.
