7.3 Rise of powerful generals and civil wars

The rise of powerful generals in ancient Rome marked a turning point in the Republic's history. Military leaders like Marius and Sulla used their armies to gain political power, weakening the Senate's authority and setting dangerous precedents for future conflicts.

This period saw intense rivalries between ambitious generals, culminating in civil wars that tore the Republic apart. The actions of Caesar, Pompey, and eventually Octavian led to the fall of the Republic and the birth of the Roman Empire.
