Timestamped Summary

00:00 Gaius Marius overhauled the Roman military with the Marian reforms in 107 BC.
01:48 The Marian reforms were necessary in Rome because the soldiers were poorly paid and had to purchase their own weapons and armor, leading to a social division based on wealth and property.
03:23 The Roman army was divided into different groups based on wealth and experience, with the elite trarii being the fighters of last resort, the equestrian class serving as cavalry, and the lowest class being ineligible for military service.
04:50 Gaius Marius's reforms removed the property requirement for military service, allowing a larger pool of talent to join the army and creating a permanent standing army.
06:25 Gaius Marius's reforms included the general equipping the army, creating a standing army that trained constantly, making the army more mobile by requiring soldiers to carry their own gear, and changing the Roman tactical units.
08:00 The Maniple system was replaced by the Cohort, a more flexible and homogenized unit consisting of about 480 soldiers, allowing for greater versatility and coordination in battle.
09:40 Marius also standardized the legion's standards, making every legion use an eagle, and extended Roman citizenship to any Italian who fought in a Roman legion, which ultimately led to a shift in loyalty from the republic to the general and later emperor.
