The New Army, The New Loyalty
Rome’s armies were once landed citizens—bound to the soil and invested in its fate. Marius needed soldiers, fast, so he tossed out old rules. He turned Rome’s desperate and jobless into a professional army, loyal to their general, not the Senate. The Republic would never be the same.

Future generals—Sulla, Caesar—will use armies that answer to them, not Rome. Marius arms the state, but also plants the seed of civil war.
