History

Dated history of Roman military (c. 6th century BCE-5th century CE in the West (East continues as Byzantine -- a sequel file)) in Italy, then the Mediterranean and European-Near Eastern frontiers.

Educational history. Casualty figures are documented ranges. This is not operational advice, a ranking of nations, or a how-to for weapons or coups.

Quick answers

Are the scores a ranking of nations or armies?

No. Scores are browsing aids inside an era-bounded atlas — not live league tables of countries.

What were the Marian reforms?

A traditional story that Gaius Marius created a professional, landless legion in the late second century BCE. Specialists now argue about how sudden or how Marian the changes were. Use as a debate, not as a kit list.

Did Rome have a navy?

Yes -- notably in the First Punic War and as standing imperial fleets. English memory under-teaches it beside the legion.

What is Vegetius?

A late Roman writer whose Epitoma was read for centuries as a timeless manual. It is a source about late anxiety and earlier ideal types -- not a guide to fight like a legionary.

Why is cultural memory so high?

Because Latin, Christianity's Roman afterlife, Hollywood, and tourism stacked a thick file. Memory is not the same as understanding pay and citizenship.

Is a Korean comparison allowed?

As institutional analogy (conscription, frontier cost), yes. As racial or "martial people" talk, no.

Start with the Italian alliance, not with a Hollywood helmet. The Republic wins as a system.

Civil war is not a side quest; it is the imperial origin.

  2. Zama

    Scipio and the end of the Hannibalic War.

  3. Marius's consulships

    The professionalisation debate's named hinge.

  4. Social War

    Citizenship as a military crisis.

  5. Caesar's civil war

    A provincial army as a political subject.

    Octavian's war at sea; the imperial preface.

  8. Trajan's Dacia

    The column as propaganda and source.

  9. Adrianople

    A late field-army disaster in the public file.

  10. West's conventional end

    A classroom date; the East continues.

Eras

Republican levy

Italy to a Mediterranean win.

Professional and civil war

Marius to Actium.

High empire

Pay, forts, a famous peace with wars on the edge.

Third-century crisis

Usurpation as a military rhythm.

Late West

Diocletian-Constantine structures; Vegetius; a classroom end.

Milestones

Zama, 202 BCE

A levy system survives Hannibal.

Actium, 31 BCE

A civil war ends in a navy's photograph.

Adrianople, 378

A late army's public disaster.

476 is a classroom door, not the only end. Name the East.

Vegetius is a late mood, not a universal key.
