Roman Army History

The Roman army (Latin: exercitus Romanus) was the terrestrial armed forces deployed by the Romans throughout the duration of Ancient Rome, from the Roman Kingdom (to c. 500 BC) to the Roman Republic (500 - 31 BC) and the Roman Empire (31 BC - 395), and its medieval continuation the Eastern Roman Empire. It is thus a term that may span approximately 2,206 years (753 BC to 1453 AD), during which the Roman armed forces underwent numerous permutations in composition, organisation, equipment and tactics, while conserving a core of lasting traditions.
