The Audit of the Eight Hundred Years

Why the West, and Not the East

The volume's first closing question is the comparative one, because the empire's own eastern half is the control-group history rarely provides: the same state, the same army-structure, the same enemies at the door — and a thousand more years. The Editor assembles the volume's evidence into the standard answers and weighs them. Geography: the East's exposed frontier was one river and one desert against the West's two rivers and an ocean of coastline; and behind the Danube stood Constantinople — the Theodosian walls repaired in sixty days under Hunnic threat, the city unstormable until gunpowder — so that no eastern catastrophe, not Adrianople, not the Utus, could be converted by its victors into the capital's capture, while the West's heart lay open to any fleet at Carthage. Money: the East was simply richer — Egypt and Syria and Asia intact through every convulsion, the tax-machine unbroken — and this volume has shown what the difference purchased: the East paid Attila six thousand pounds of gold a year as a budget-line and survived; the West lost Africa's revenues and could not, in thirty-seven years of trying, buy them back. Politics: the East kept the throne and the army separate — its fifth-century emperors were civilians ruling through interchangeable generals, its dangerous generalissimo (Aspar) eventually destroyed by the palace rather than the reverse — while the West fused them, so that every military crisis was a succession crisis and every Ricimer irreplaceable. And settlement: the East deflected its federate nations westward — the compendium has watched Constantinople export Alaric, decline Attila, and finance the Ostrogoths' eventual departure for Italy — while the West absorbed them, until the army of Italy in 476 was the dissolved Hun empire under new management, asking for the standard terms. None of these answers excludes the others; together they are the volume's finding: the West did not die of barbarians, whom it had digested for five centuries, but of the conjunction — fiscal amputation, political fusion, and geographic exposure — that made the standard remedy, hiring the enemy, into the mechanism of transfer.

The Instrument, Concluded

The compendium's constant has been the army, and the series closes its file. Eight hundred years separate the levy that drowned at the Allia from the federate regiments that petitioned Odoacer, and the whole arc is visible from here: the citizen-militia of Books I–II, annihilated and self-replacing, whose depth was the Republic's one unanswerable weapon; the Marian client-army of Book V, which conquered the world and ate the state; the Augustan professional establishment of Book VI, which solved the client-problem by nationalizing it and revealed, in 69, the arcanum that never afterward closed; the perimeter army of Book VII, broken by simultaneity and rebuilt as the mobile reserve; and this volume's final form — the field armies fed increasingly by treaty rather than levy, until the distinction between the army and the federate nations dissolved and the hospitalitas of soldiers became the kingdoms of Gaul, Spain, Africa, and Italy. The Editor states the series' summary theorem without decoration: Rome was destroyed by nothing except the cost of being defended. Every transformation in the sequence above was a rational answer to the last crisis's bill; each answer's price compounded; and the final settlement — paying the defenders in the one currency that could not be debased, the land itself — was the state liquidating its own substance in wages. The successor kingdoms were not the empire's conquerors; they were its army, paid off and gone into business for itself, which is why they kept the law, the language, the Church, the tax-lists, and the consular datings, and why the men who ended the western empire spent the next fifty years asking Constantinople to ratify their titles.

The Sources, Concluded; and the Series

The last audit is the one this compendium has conducted in every Editor's Note for eight volumes, now run across the whole. The series began in reconstructed legend — the Allia known from traditions four centuries after the arrows — rose through Polybius's autopsy and Caesar's self-authored campaigns to the documentary noon of the Principate, watched the third century's narrative go dark while the stones talked, recovered Ammianus, and ended in chronicle-clauses and one boy's pension. Across that whole range the method held: grade the witness, name the interest, trust the ground, confess the gap — and the Editor closes with the confession that contains the others: this compendium, like every history of Rome, is built overwhelmingly from the records of the victors' language, and its final volume narrated the one war Rome lost entirely — the long war against its own costs — in sources that did not know they were describing a defeat. The reader who has traveled all eight volumes is owed the series' last sentence in the register of its first: on a July day in 390 BC an army of Gauls destroyed the levy of a middling Italian city-state at a stream twelve miles from its walls, and the city, against every precedent of its world, declined to accept the verdict; on a September day in AD 476 the last emperor of that city's West, a boy named for its founder, handed his diadem to a Gaul's remote heir and accepted a pension — and between those two days lies the largest single fact in the political history of the western world, which this compendium has now narrated, graded, and closed. The wars of Rome are ended. The argument about them, the Editor is confident, is not; the apparatus was built for the argument, and is hereby delivered to it.
