What unit from the Roman Army consisting of centuries enjoyed more prestige than the Roman navy?
Roman legion A Roman legion (from Latin "legio" "military levy, conscription", from "legere" "to choose") was the largest unit of the Roman army, evolving from 3000 men in early times to over 5200 men in imperial times, consisting of "centuries" as the basic units. Until the middle of the first century, 10 cohorts (about 5,000 men) made up a Roman Legion. This was later changed to nine cohorts of standard size (with 6 centuries at 80 men each) and one cohort, the first cohort, of double strength (5 double-strength centuries with 160 men each).
Crisis of the Third Century The Crisis of the Third Century, also known as Military Anarchy or the Imperial Crisis (AD 235–284), was a period in which the Roman Empire nearly collapsed under the combined pressures of invasion, civil war, plague, and economic depression. The crisis began with the assassination of Emperor Severus Alexander by his own troops in 235, initiating a 50-year period in which there were at least 26 claimants to the title of Emperor, mostly prominent Roman army generals, who assumed imperial power over all or part of the Empire. The same number of men became accepted by the Roman Senate as emperor during this period and so became legitimate emperors.
