Marius Builds a New Kind of Army
Around 107 B.C.E., the Roman general Marius transformed the Roman military by creating a professional army open to landless citizens. Previously, soldiers had to own land to serve — but as poverty spread and land ownership declined, the Republic struggled to fill its ranks. Marius solved the manpower shortage by offering landless men wages and land grants after service. The unintended consequence was profound: soldiers now owed loyalty to the general who paid them rather than to the Republic, creating private armies that ambitious leaders used to seize political power and ultimately destabilize Rome. This 6th grade topic is in Chapter 9 of IMPACT California Social Studies, Grade 6.
Key Concepts
As Rome's problems grew, its army faced a shortage of soldiers. Many poor citizens no longer owned land, which had been a requirement for military service.
Around 107 B.C.E., a general named Marius changed the rules. He created a professional army by recruiting these landless men. He promised them a salary and, more importantly, land of their own after their service was over.
