What is a roman ally?

A Roman ally, or "socius," was a non-Roman community or state that maintained a cooperative relationship with the Roman Republic or Empire. These allies often provided military support, resources, or manpower in exchange for protection, trade privileges, and a degree of autonomy. While they were not full citizens of Rome, their alliances were crucial for Rome's expansion and control over vast territories. The status of allies varied over time, influencing their rights and obligations within the Roman political system.
