Key points5

The Marian reforms refer to a series of structural and social changes to the Roman army traditionally attributed to the general Gaius Marius in 107 BC.
These reforms are considered a pivotal moment in the history of the late Roman Republic, fundamentally altering how the military was recruited and organized.
Central to these changes was the process of proletarianisation, which allowed citizens without property to enlist in the legions.
By removing the property requirement, the military shifted toward a semi-professional force.
This transition created a new dynamic where soldiers became increasingly dependent on their commanders for land grants upon retirement, effectively turning the army into a political tool used by ambitious generals to challenge the existing republican order.

Summary

A series of military reforms that allowed landless citizens to join the army, creating a professional force loyal to their generals.
