A general by the name of Gaius Marius began to change the army. He was afraid that Rome was going to be attacked by barbarians. The Romans called everyone who wasn't a Roman or Greek a barbarian. He began to let poor plebeians join the army. From now on, generals paid their soldiers. The soldiers were now loyal to their general, not the Republic.
