It has been estimated that at the beginning of the empire, about 750,000 Italians lived in the provinces. Julius Caesar, Mark Anthony and Octavian settled many of their veterans in colonies: in Italy, and the provinces. The colonies that were established in Italy until 14 BCE have been studied by Keppie (1983). In his account of the achievements of his long reign, "Res Gestae Divi Augusti", Augustus stated that he had settled 120,000 soldiers in twenty colonies in Italy in 31 BCE, then 100,000 men in colonies in Spain and southern Gaul in 14 BCE, followed by another 96,000 in 2 BCE. Brian Campbell also states "From 49 to 32 BCE about 420,000 Italians were recruited", which would thus be the veteran (citizen) stock that was largely sent to the provinces (colonies) during Augustus. The Lex Calpurnia, however, also allowed citizenship to be granted for distinguished bravery. For example, the 1,000 socii from Camerinum after Vercellae 101 BCE (Plutarch Mar. XXXVIII) and the auxiliary (later Legio XXII Deiotariana) after Zela, got Roman citizenship. By the time of Augustus, the legions consisted mostly of ethnic Latins/Italics and Cisalpine Gauls.
