Legatus legionis was a title awarded to legion commanders in Ancient Rome.


By the time of the Roman Republic, the term legatus delegated authority (usually a consul or proconsul). Julius Caesar made wide use of the title throughout the Gallic Wars.[1]

From Augustus, the emperor gave the title of legatus legionis to senior commanders (former military tribunes) of a legion, except in Egypt and Mesopotamia, where the legions were commanded by a praefectus legionis of an equestrian rank. The legatus legionis was under the supreme command of Legatus Augusti pro praetore of senatorial rank. If the province was defended by a single legion, the Legatus Augusti pro praetor was also in direct command of the legion.

A legatus legionis could order capital punishment.[2]

The senatorial legatus legionis was removed from the Roman army by Gallienus, who preferred to entrust the command of a legionary unit to a leader chosen from within the equestrian order who had a long military career.

This post generally lasted 3 or 4 years, but could be much longer.[3] A legatus legionis was usually from a wealthy or important family.[4]
