In a process known as the Marian reforms, Roman consul Gaius Marius carried out a programme of reform of the Roman military. In 107 BC, all citizens, regardless of their wealth or social class, were made eligible for entry into the Roman army.* Santosuosso, "Storming the Heavens", p. 10</ref> This move formalised and concluded a gradual process that had been growing for centuries, of removing property requirements for military service. The distinction between "hastati", "principes" and "triarii", which had already become blurred, was officially removed, and the legionary infantry of popular imagination was created. Legionary infantry formed a homogeneous force of heavy infantry. These legionaries were drawn from citizen stock; by this time, Roman or Latin citizenship had been regionally expanded over much of ancient Italy and Cisalpine Gaul. Lighter citizen infantry, such as the "velites" and "equites", were replaced by non-citizen auxiliaries ("auxilia") that could consist of foreign mercenaries. Due to the concentration of the citizen legions into a force of heavy infantry Rome's armies depended on auxiliary cavalry attachments for support. As a tactical necessity, legions were almost always accompanied by an equal or greater number of lighter auxiliary troops, which were drawn from the non-citizens of the Empire's territories. One known exception of legions being formed from non-citizen provinces during this period was the legion that was raised in the province of Galatia.
