How to read this class
DOCUMENTED = the fact stands in a named primary, legal or inscriptional record. DEBATED = the sources or the scholarship conflict; both sides are printed. CLAIM = asserted without a record at that standard, and labelled where it stands. The era's best historian, Ammianus Marcellinus, was a serving officer and an eyewitness to much of what he records; where the sources thin out after him (the 5th-century West), the page says so rather than filling the quiet. No modern carrier identities appear in this class.
§1 — 313: what Milan did, and what it did not do
DOCUMENTED. The house's Rome class ends at 313 with the persecution closing; this class begins there. The settlement agreed by Constantine and Licinius at Milan in 313 — its implementing letter preserved by Lactantius (On the Deaths of the Persecutors 48) and by Eusebius (Church History 10.5), and conventionally called the Edict of Milan — granted Christianity legal standing in the empire and ordered its confiscated meeting-houses and property restored. It did not make Christianity the religion of the empire. It ended a persecution; the privileging of one church over all others proceeded by stages across the century that followed, and the stages are the record: Constantine's councils at Arles (314) and Nicaea (325) — the creed agreed there and the Easter settlement, the council's own documentary record partial and labelled as such; his church-building from Rome to Jerusalem; a court, a civil service and an army still full of pagans for two generations; an emperor, Julian (r. 361–363), who tried to reverse the whole movement and died campaigning against Persia (§4), his failure measured by how little of the machine his eighteen months could move. In 380 came the legal definition: the emperors' decree at Thessalonica (Codex Theodosianus 16.1.2, Cunctos populos) ordered all their peoples to hold the faith “which the divine Apostle Peter transmitted to the Romans” — orthodoxy defined by law, in the law's own words, DOCUMENTED. The temple laws of 391–392 (Cod. Theod. 16.10.10–12) forbade sacrifice and temple worship, and the destruction of Alexandria's great Serapeum in 391/392 (Rufinus; Socrates; Sozomen — the church historians' accounts differ in detail) stands as the era's emblem. The Olympic festival disappears from the record after 393; a formal decree abolishing it is not documented, and this class does not print one.
§2 — Division, 395: two courts, one name
DOCUMENTED. The empire had been administered in halves since Diocletian's reforms. At Theodosius's death in 395 his sons took the two courts — Arcadius in the East, Honorius in the West — and no emperor ever ruled the whole again. It was a division of courts, armies and tax revenues, not yet a fall: the laws still ran in both emperors' names, and the East still sent the West armies when it could. But the halves were not equal. The East was richer, more urban, harder to invade, and defensible behind Constantinople's straits and, from about 413, the Theodosian land walls. The West's tax base shrank as province after province passed, in fact if not in law, to federate peoples settled inside the frontier under their own kings; its armies were increasingly those peoples, under commanders — Stilicho the Vandal-born, Aetius, Ricimer — who were themselves the frontier become the government. What follows in §3 is therefore told as the record gives it: not an empire struck down on a date, but a western state dissolving by stages across three generations, while an eastern state of the same name, law and faith endured for a thousand years.
§3 — The peoples on the move, and the fall of the West as a process
DOCUMENTED — the crossing and Adrianople. In 376 the Goths, pressed westward by the Huns (Ammianus 31.2 gives the Huns their first Roman-era portrait — an enemy's ethnography, and read as such; for the Huns' steppe world and the Xiongnu question, cross-link The Steppe World), petitioned to cross the Danube and were admitted as refugees. Ammianus names what followed without flinching: the officials Lupicinus and Maximus profiteered from the refugees' starvation, trading dog-meat for Gothic children sold into slavery (31.4–5). The Goths revolted. On 9 August 378, at Adrianople, the eastern field army was destroyed and the emperor Valens killed on the field; Ammianus (31.13) reaches for the only comparison his history holds: Cannae. The settlement of 382 left the Goths inside the empire, armed, under their own chiefs — a precedent with a long fuse, and the single most argued-over decision of the era.
DOCUMENTED — 410 and after. Alaric, the Gothic king who had also held Roman command, marched on Rome when his people's demands for land, pay and standing were refused, and on 24 August 410 his army entered by the Salarian Gate. The sack lasted three days; by the Goths' orders — they were Arian Christians — the great churches stood as sanctuaries and those who fled to them were spared (Orosius 7.39–40). Jerome, writing from Bethlehem (Letter 127.12), grieved in the era's most quoted sentence: “the bright light of all the lands was quenched… in one city the whole world perished” — grief at first hand, and rhetoric, and labelled as both. Augustine spent thirteen years answering the charge that the Christian God had failed the city, in the City of God, begun in 413. Rome was not the capital any longer — the court sat at Ravenna — and the empire in the West did not end in 410. What ended the West, by stages, was the loss of its provinces and their taxes: Gaul and Spain passing to Gothic, Burgundian and Frankish kingdoms through the 410s–470s; and the mortal wound, Africa — the grain province — taken by the Vandals under Genseric, who crossed in 429 and took Carthage in 439. A Vandal fleet sacked Rome itself for fourteen systematic days in 455. Britain, by contrast, simply lapsed: no invasion narrative survives, the coin supply stops, and the province fades from the record in the early 5th century — a different kind of ending, and the page prints it as one.
DOCUMENTED — the Huns, at the one eyewitness. Under Attila (sole ruler from 445) the Hun empire on the Danube drew gold tribute from Constantinople, invaded Gaul in 451 — checked at the Catalaunian Plains by Aetius's coalition of Romans and Visigoths, in an account Jordanes wrote a century later and embroidered, labelled as such — and Italy in 452, where the invasion turned back before Rome. Famine and disease in Italy, eastern Roman pressure on the Hun heartland, and the embassy of Pope Leo all stand in the sources; that Leo's meeting with Attila was itself decisive is DEBATED. Attila died in 453, on his wedding night, of a haemorrhage (Priscus's account, via Jordanes); his sons' empire broke at the river Nedao in 454. What survives him whole is Priscus of Panium's fragment of his own embassy of 449: the wooden palace in a great stockaded camp, the banquet's strict order of seating, the gold and silver cups of the guests against Attila's wooden cup and plain food — the one eyewitness portrait of the Hun court, quoted here at its class.
DOCUMENTED — the Rhine crossing, 406. Between Adrianople and the sack stands the era's other hinge. On the last night of 406 — the date is traditional, the season is the record's — Vandals, Alans and Suebi crossed the frozen Rhine in force near Mogontiacum (Mainz), and the frontier in Gaul never closed behind them (Jerome's letter 123 lists the cities taken and the peoples on the move, tribe by tribe). The western court, fighting usurpers and Goths at once, could not expel them; the crossing peoples wandered Gaul for years, passed into Spain in 409, and the Vandals among them crossed to Africa twenty years later to take the province whose loss (§3) cut the West's grain and taxes away. Britain's garrison, stripped for the usurpers' continental bids, was gone in the same years. The “process” of this section is not an abstraction laid over sudden events: it is what a frontier looks like failing at several points across three generations, each failure making the next likelier, while the eastern half of the same empire — facing the same peoples with more money, shorter land frontiers and one great walled capital — held.
DOCUMENTED — 476, and why it is not the headline. On 4 September 476 the Germanic officer Odoacer deposed the last western emperor, a boy whose name history kept for its irony — Romulus Augustulus — and sent the imperial insignia east to Constantinople (Marcellinus Comes, Chronicle, s.a. 476). No contemporary treated the date as the end of the world; Roman law, the Senate, the coinage and the consulship ran on in Italy under Odoacer and then under Theoderic's Ostrogothic kingdom (from 493), which governed Italy in Roman forms for a generation. The West's fall is therefore taught in this class as it stands in the record: a process — 376, 378, 382, 406, 410, 429–439, 455, 476 are its dated stations, not a single blow — while the rival scholarly emphasis, that the material losses were catastrophic and “transformation” too soft a word for a world that lost its pottery, its coinage, its literacy and its roofs of tile across whole provinces, is carried DEBATED beside the transformation frame, exactly as the scholarship argues it. A student should leave this section able to state both, and to name the evidence each rests on.
§3A — How they lived while it changed
DOCUMENTED. The bridge was crossed by ordinary people, and the record of their lives thickens precisely where the political record thins. The great change at street level was institutional: the church became the city's welfare machine and its career ladder — bishops distributing grain and ransoming captives, churches and hostels rising where temples closed, the poor registered on church lists as the widows and distressed of Rome had been a century before the persecutions ended (the Chronology's Era 1 fills carry that earlier list). A new way of life appeared inside the empire's own borders: the ascetics. Antony of Egypt (d. 356), whose Life by Athanasius became the age's bestseller, withdrew to the desert and drew a movement after him; Pachomius organised monks into ruled communities in Egypt in the 320s; Simeon Stylites (d. 459) spent a lifetime atop a pillar in Syria and drew the crowds of two empires to its foot — pilgrimage, letters of advice to emperors included, conducted from six metres of platform (Theodoret's account, a contemporary's). In the countryside the villa world thinned unevenly — in Gaul and Italy aristocratic estates and their mosaics run on deep into the 5th century (the poet-bishop Sidonius Apollinaris's letters describe Gallic villa life, baths and verse and hunting, under Visigothic rule, from inside it) while in Britain the towns, the coinage and the potteries lapse within a generation. One empire's transformation was another province's collapse, at the material record — the DEBATED frame of §3, felt at the level of a roof and a coin.
DOCUMENTED — the faith dividing as it triumphed. Christianisation did not mean unity. The councils that defined the faith also drew its fractures: Nicaea (325) against Arius — and Arian Christianity, carried to the Goths by the missionary-bishop Ulfilas, who translated the scriptures into Gothic (the earliest substantial Germanic text; Philostorgius's record, carried in the Rome class), became the confession of the Gothic, Vandal and Lombard kingdoms, so that the West's new rulers were Christians of a kind the empire's law called heresy — a fact that shaped every negotiation between a Gothic king and a Catholic population. Ephesus (431) and Chalcedon (451) divided the East itself: the churches of Egypt and much of Syria rejected Chalcedon's formula, and the schism that followed outlasted the empire in the Coptic and Syriac churches standing today. The bridge thus carries a warning the next volume inherits whole: in late antiquity, to define the faith by law was also to manufacture the dissent the law then had to govern.
DOCUMENTED — the successor kingdoms in Roman forms. The West's new kingdoms governed more Romanly than their reputations. Theoderic's Italy (493–526) kept the Senate, the consulship, the grain supply and the aqueducts, issued law in Roman forms, and left its king's letters — drafted by Cassiodorus, preserved in his Variae — as the record of a Gothic court running a Roman state. In Gaul, Clovis the Frank (r. 481–511) took baptism into the Catholic faith — the year is DEBATED (496 and 508 both argued, Gregory of Tours's account written a lifetime later) — the one Germanic king to choose the majority faith of his Roman subjects, and his kingdom became France. The Vandals in Africa, Arian rulers of a Catholic population, persecuted where the Goths had bargained (Victor of Vita's History of the Vandal Persecution — a Catholic victim's record, labelled as such). Romanity after Rome was not a memory; it was the operating system every successor state ran, at different settings — and the settings, kingdom by kingdom, are the story Volume M1 inherits in the West while Constantinople carries the unbroken original east.
§4 — Persia's last Sasanian centuries: the other empire, unfallen
DOCUMENTED. Rome's mirror stood through the whole bridge. The Sasanian empire, founded in AD 224 when Ardashir overthrew the Parthians, was Rome's peer for four centuries — and the companion classical class's Persia, six hundred years on, organised on the same imperial grammar of king of kings, provinces and a state faith. Shapur I (r. 240–270) beat Rome in three campaigns and captured the emperor Valerian alive in 260 — his own trilingual inscription at Naqsh-e Rostam (the SKZ) lists the Roman armies destroyed and the deported city populations settled in Persis, who built in Khuzistan as Rome's captives had built at home; the Rome class carries Valerian's capture as the close of his persecution, and this class does not duplicate it. Beside the kings stands the priest Kartir, whose inscriptions boast the raising of fire temples and the suppression of rival faiths — Persia's own record of its Zoroastrian establishment. Under Shapur II, from 339/340, Persian Christians were persecuted as suspected friends of a now-Christian Rome (the Syriac martyr acts carry the record, labelled as acts): the two empires' religions had become each other's foreign policy. Julian's invasion of 363 ended with the emperor dead on the retreat Ammianus marched in and wrote (Book 25); his successor Jovian ceded Nisibis and five provinces to buy the army's way home. Thereafter, with wars between, the peace of 387 partitioned Armenia and the two empires jointly maintained the Caucasus passes against the steppe — the frontier both of them faced. The 5th century brought Persia its own steppe crisis in the Hephthalites on its eastern frontier, kings killed and ransomed (Peroz I fell against them in 484), and its own internal religious-political upheaval in the Mazdak movement at the century's end. Persia stands in AD 500 as it stood in 313: unconquered, administered, and Rome's equal. Its fall, when it came in the next century, came from Arabia — and belongs to Volume M1, not to this bridge.
§5 — Byzantium born, inside this volume's dates
DOCUMENTED. Constantine dedicated Constantinople on 11 May 330, on the site of Byzantion, where Europe meets Asia and the Black Sea meets the Aegean: a New Rome with its own senate, its own Egyptian grain supply, its fora and its great churches. The 5th century made it a capital in full: the Theodosian Walls (c. 413), triple lines of wall, moat and towers that no enemy breached for a thousand years; a state-salaried university refounded by Theodosius II's decree of 425, its chairs of grammar, rhetoric, philosophy and law named in the law itself (Cod. Theod. 14.9.3); the Codex Theodosianus of 438, the first official codification of the empire's laws since the early Republic; and a population the estimates place in the several hundred thousands — the figure DEBATED, the scale not. Its streets were turning Greek while its law and army kept Latin forms; its church, its court ceremonial and its fiscal machine were becoming things Rome had never quite been. The empire that the next volume opens with is therefore not born in 500, or in 476, or at any later date a syllabus chooses: it is born here, between 330 and 450, inside this class's years — which is why this bridge ends by handing its reader east.
The hand-off. In AD 500 the map this volume closes on holds: an eastern Roman empire at Constantinople, solvent and walled; an Ostrogothic Italy governing in Roman forms; Frankish, Burgundian, Visigothic and Vandal kingdoms in the old West; a Sasanian Persia unfallen on the Euphrates frontier; a Gupta India thinned by the Huna; a China divided between northern and southern dynasties since the Han fell — and, off this volume's edge, Arabia, where the next volume's second subject is gathering. Byzantium and Islam (Volume M1) takes the story from exactly here.
§6 — What the bridge carries forward
DOCUMENTED, as the volume's own summary. Four things cross this bridge and structure everything after it. First, a Christian empire: by 500 the faith the persecutions tried to burn out of the market-places in 303 is the state's own, defined by its law and divided by its councils — in the East for another thousand years, in the West as the one institution, the church, that outlasts the state that adopted it. Second, two successor worlds in the West: kingdoms governing Roman populations in Roman forms under Germanic kings, whose law codes, written in Latin in the following century, are Volume M1's opening evidence. Third, Persia entire: the bridge is not Rome's story with Persia at its edge — the Sasanian empire crosses it at full strength, and falls outside it, to a power neither empire foresaw. Fourth, the steppe's peoples inside the frontier: Goths, Vandals, Franks, Huns and Hephthalites move through every section of this class, as refugees, soldiers, kings and invaders in turn — the frontier peoples becoming the successor states is late antiquity's deepest pattern, and the Steppe class, cross-linked throughout, is its long record. The missing millennium that older syllabuses skipped is missing no longer in this history: it begins here, in a world already transformed, not in a darkness that fell at a date.
