The '''Roman army''' ({{Langx|la|exercitus Romanus}}) served [[ancient Rome]] and the [[Roman people]], enduring through the [[Roman Kingdom]] (753–509 BC), the [[Roman Republic]] (509–27 BC), and the [[Roman Empire]] (27 BC–AD 1453), including the [[Western Roman Empire]] (collapsed [[Fall of the Western Roman Empire|AD 476/480]]) and the [[Byzantine Empire|Eastern Roman Empire]] (collapsed [[Fall of Constantinople|AD 1453]]). It is thus a term that broadly spans approximately 2,206 years, during which the force underwent numerous permutations in [[Size of the Roman army|size]], [[Military of ancient Rome|composition]], [[Structural history of the Roman military|organization]], [[Roman military equipment|equipment]] and [[Strategy of the Roman military|tactics]], while conserving a core of lasting traditions.<ref>The Complete Roman Army, Adrian Goldsworthy Thames & Hudson, 2011</ref><ref>Companion to the Roman Army, Paul Erdkamp, John Wiley & Sons, 31 March 2011</ref><ref name=":0">{{Cite book|last=Southern|first=Pat|url=https://books.google.com/books?id=b3UHGXny-NwC&q=Tactics+of+the+Roman+Army&pg=PT16|title=The Roman Army: A Social and Institutional History|date=2007|publisher=Oxford University Press|isbn=978-0-19-532878-3|language=en |author-link= Pat Southern}}</ref>
