benefits on the army in accordance with the advice of his father to keep their loyalty, and considered dividing the Empire into eastern and western sectors with his brother Geta to reduce the conflict in their co-rule. But with the major influence of their mother, Julia Domna, this division of the empire was not possible. Instead of warring in foreign lands, the Roman empire was increasingly put on the defensive by marauding enemies and civil wars. This cut off the essential source of income gained from plundering enemy countries, while opening up the Roman countryside to economic devastation from looters both foreign and domestic. Frequent civil wars contributed to depletion of the army's manpower, and drafting replacement soldiers strained the labour force further. Fighting on multiple fronts, increasing size and pay of the army, increasing cost of transport, populist "bread and circuses" political campaigns, inefficient and corrupt tax collection, unorganised budgeting, and paying off foreign nations for peace all contributed to financial crisis. The emperors responded by confiscating assets and supplies to combat the deficit. The situation of the Roman Empire became dire in 235. Many Roman legions had been defeated during a previous campaign against Germanic peoples raiding across the borders, while the emperor Severus Alexander had been focused primarily on the dangers from the Sassanid Empire. Leading his troops personally, the emperor resorted to diplomacy and accepting tribute to pacify the Germanic chieftains quickly, rather than military conquest. According to Herodian this cost Severus Alexander the respect of his troops, who may have felt that more severe punishment was required for the tribes that had intruded on Rome's territory. The troops assassinated Severus Alexander and proclaimed the new emperor to be Maximinus Thrax, commander of one of the legions present. Maximinus was the first of the barracks emperors – rulers who were elevated by the troops without having any political experience, a supporting faction, distinguished ancestors, or a hereditary claim to the imperial throne. As their rule rested on military might and generalship, they operated as warlords reliant on the army to maintain power. Maximinus continued the campaigns in Germania but struggled to exert his authority over the whole empire. The Senate was displeased at having to accept a peasant as Emperor. This precipitated the chaotic Year of the Six Emperors during which all of the original claimants were killed: in 238 a revolt broke out in Africa
