マリウスの軍制改革
The Marian reforms were reforms of the ancient Roman army implemented in 107 BC by the statesman Gaius Marius, for whom they were later named. The reforms originated as a reaction to the military and logistical stagnation of the Roman Republic in the late 2nd century BC. Centuries of military campaigning throughout the Mediterranean and increasing invasions and uprisings across Roman territory had stretched the human and physical resources of the Roman army.
