Socii

The socii (/ˈsoʊʃiaɪ/ in English; "allies") were the autonomous tribes and city-states of the Italian Peninsula in permanent military alliance with the Roman Republic until the Social War of 91–88 BC. After this conflict, all Rome's peninsular Italian allies were awarded Roman citizenship and their territories incorporated in the Roman state. The Romans themselves referred to their confederates as the socii Latini ("Latin allies"), although most were not members of the Latin tribe strictly speaking, but members of various other Italian tribes and city-states. In everyday usage, the word socius /ˈsoʊʃəs/ could mean "associate" or "partner" in general.
