as a whole. Zosimus describes the Cyprianic outbreak as even worse. The armies and, by extension, the frontier provinces where they were based (and mainly recruited), would likely have suffered deaths at the top end of the range, due to their close concentration of individuals and frequent movements across the empire. The 3rd-century crisis started a chain-reaction of socio-economic effects that proved decisive for the development of the late army. The combination of barbarian devastation and reduced tax-base due to plague bankrupted the imperial government, which resorted to issuing ever more debased coin e.g. the antoninianus, the silver coin used to pay the troops in this period, lost 95% of its silver content between its launch in 215 and its demise in the 260s. Thus, twenty times more money could be distributed with the same amount of precious metal. This led to rampant price inflation: for example, the price of wheat under Diocletian was 67 times the typical price under the Principate. The monetary economy collapsed and the army was obliged to rely on unpaid food levies to obtain supplies. Food levies were raised without regard to fairness, ruining the border provinces where the military was mainly based. Soldiers' salaries became worthless, which reduced the army's recruits to a subsistence-level existence. This in turn discouraged volunteers and forced the government to rely on conscription and large-scale recruitment of barbarians into the regular army because of the shortfalls caused by the plague. By the mid-4th century, barbarian-born men probably accounted for about a quarter of all recruits (and over a third in elite regiments), likely a far higher share than in the 1st and 2nd centuries. Danubian military junta By the 3rd century, Romanised Illyrians and Thracians, mostly primipilares and their descendants, came to dominate the army's senior officer echelons. Finally, the Danubian officer-class seized control of the state itself. In 268, the emperor Gallienus (ruled 260–68) was overthrown by a coup d'état organised by a clique of Danubian senior officers, including his successors Claudius II Gothicus and Aurelian (270–75). They and their successors Probus (276–82) and Diocletian (ruled 284–305) and his colleagues in the Tetrarchy formed a sort of self-perpetuating military junta of Danubian officers who were born in the same provinces (several in the same city, Sirmium, a major legionary base in Moesia Superior) and/or had served in the same regiments. The Junta reversed the military disasters of 251–71
