Among other reasons, Rome built its global dominance in his militia, the Roman legions, the best army in ancient times. A body of men skilled in the art of war extremely disciplined under the command of generals able both to lead their armies in the field of battle as you lead the people from the Senate or the elections.
In the early and middle stage of the Republic, men who were the legions were Roman citizens landowners, that is, each man had paid their gear for battle, which greatly hindered the military levies, and not all citizens of Rome had enough money to enlist in the legions. Given day the year was held a meeting on Capitol Hill in which the military legacies soldiers recruited men between 16 and 45 owners. In turn, Rome required its Italian allies (Marsi, Samnites, etc.) to submit the auxiliary armies that accompany the Romans.

Continuous wars of expansion that Roma faced
caused the depletion of this mode of recruitment. Compounding the situation, the male population of working age was diminished so that there were no men to work the lands of Rome, which at one time or another caused food crisis and led to the emergence of wealthy landowners who exploited the country with slave labor for profit. At the end of s.II BC, during the war against Numidia, the consul Gaius Marius (later known as the third founder of Rome) got the Senate approve the possibility of recruiting for the legions of the known as "Captain Censi "or Head Count. The Head Count it all Roman citizens were non-owners who did not have enough annual income to be able to vote at centuries. All materials needed to battle the Roman treasure would pay and salaries. In this way, Rome professionalize its army. In addition, Mario led also a law that once you leave the troops, gives each Legionnaire land ownership in the various Roman provinces. These measures had an immediate success driving new conquests and kill two birds with one stone. Eventually, the unconditional adherence of the legionaries to the respective commanding generals who lead them civil wars if AC


were four types of legionnaires. The "hastati" (first line) and the "princeps" (second line) were the infantry and the main army. In the rear, were the "triarii", a group of army veterans. The last group was composed of the velites play a role harassing the enemy, acted in a more dispersed and free than the rest Legionnaires. The first two were equipped by the famous short sword (gladius hispaniensis ") intended to make cuts rather than endlessly useless when attacking large espadazo in formation, and two spears known as" pilum. " The triarios replaced the "stack" for a much longer throws in imitation of the Greek phalanx. While the velites only weapons were a series of lighter than spears of the infantry to fulfill their missions. On the defensive, the legionnaires had a helmet, shield larger or smaller depending on the type, bracers, greaves and breastplate or chain mail.
As support forces, the flanks of the infantry, cavalry stood composed of men with greater economic power. The legions also relied on instruments of harassment and battering rams, catapults and crossbows.
But Marius, not only introduced reforms in the political sphere as seen above, but set far-reaching changes in the military itself. Mario
out the distinction between the bulls, the triarios and "princeps", equipping them all in the same way, and eliminated the kind candles that became part of the auxiliary troops. As the unit was replaced by the handpiece cohort and increase the number to form a century from 60 to 80. Since then, a legion would consist of ten cohorts numbered from the I to X.
to Mario, the legions marched always accompanied by a large convoy carrying everything needed for campaigns. This convoy was easy and tempting prey for the enemy. Mario arranged for each Legionnaire to take responsibility for their basic equipment. The legionnaires carried two sticks in a cross on his shoulder hanging, for example, molting, socks, water bottle, food rations and camping tools. The shield is held him behind his back like a backpack. Eight men had a mule he was carrying, among others, the leather shop, spears and supplementary food supplies. These changes led to a march much lighter army up to 50km. in a day. Be known as "mules Mario."
