## Slide Transcript

### Slide 1: ROMA

- Imperium
- &#10070;
- S P Q R
- Senātus Populusque Rōmānus &mdash; The Senate and People of Rome
- A thousand years, in thirteen acts. 753 BC &mdash; 476 AD.

### Slide 2: The She-Wolf and the Twins

- 753 BC &middot; The Founding Myth
- By legend, twin princes Romulus and Remus were cast into the Tiber, suckled by a she-wolf, and raised by a shepherd. Grown, they fought to found a city on the Palatine Hill. Romulus killed Remus. The city took his name.
- Beyond the myth: a cluster of Iron-Age villages on seven hills, perched above a river crossing, gradually fused into a town &mdash; Latin in tongue, Etruscan in early kings, mercantile in instinct.
- "From a small thing, mighty things." &mdash; Lucretius

### Slide 3: The Republic is Born

- 509 BC &middot; Res Publica
- The last king, Tarquin the Proud, was overthrown. Rome became res publica &mdash; "the public thing." Power was deliberately split, balanced, and term-limited.
- Senate
- Three hundred elders. Advisory in theory, dominant in practice. The institution that outlived everything.
- Consuls &times; 2
- Two annually elected magistrates. Each could veto the other. Power feared itself.
- Cursus Honōrum
- Quaestor &rarr; Aedile &rarr; Praetor &rarr; Consul. A ladder of office, age-gated and earned.
- A constitution mostly unwritten, mostly observed &mdash; until it wasn't.

### Slide 4: Rome vs. Carthage

- 264 &mdash; 146 BC &middot; The Punic Wars
- First (264&ndash;241): Sicily. Rome learns to build a navy by copying a wrecked Carthaginian ship.
- Second (218&ndash;201): Hannibal crosses the Alps with elephants, annihilates Roman armies at Cannae &mdash; and still loses. Scipio Africanus takes the war to Africa and wins at Zama.
- Third (149&ndash;146): Carthage is razed. "Carthāgō dēlenda est." Salt, allegedly, on the ground.
- After Carthage, Rome had no peer in the western Mediterranean &mdash; and a hundred years of provincial wealth that the Republic could not digest.

### Slide 5: Gaius Julius Caesar

- 100 &mdash; 44 BC
- 58&ndash;50 BC Conquest of Gaul. Eight years, a million dead, a million enslaved &mdash; and a private army loyal to Caesar, not Rome.
- 49 BC Ordered to disband, he crosses the Rubicon. "Ālea iacta est." The die is cast.
- 48&ndash;45 BC Civil war. Pompey killed in Egypt. Caesar emerges dictator perpetuō.
- 44 BC The Ides of March. Twenty-three knife wounds on the Senate floor. "Et tū, Brūte?"
- He was not the first general to march on Rome. He was the one who made it stick.
- Reformed the calendar &mdash; 365.25 days, the Julian.
- Wrote his own dispatches: "Vēnī, vīdī, vīcī."
- His name became a title &mdash; Caesar, Kaiser, Tsar.

### Slide 6: Augustus & the Principate

- 27 BC &mdash; 14 AD
- Caesar's grand-nephew Octavian outlasted Antony and Cleopatra at Actium (31 BC). Returning to Rome, he did something subtler than crowning himself king: he kept the Republic's furniture, called himself "first citizen" (prīnceps), and quietly held every meaningful office at once.
- The Senate voted him the name Augustus &mdash; "the revered one."
- Standing armies, professional bureaucracy, an imperial post.
- Pax Rōmāna: roughly two centuries of relative peace across the Mediterranean.
- "I found Rome a city of brick and left it a city of marble."
- The Republic did not fall in a day. It was hollowed out, then ceremonially preserved &mdash; a constitutional taxidermy that lasted three hundred years.

### Slide 7: Greatest Extent

- 96 &mdash; 180 AD &middot; The High Empire
- Trajan (117 AD): Empire at maximum &mdash; from Britain's Tyne to the Persian Gulf, 5 million km&sup2;, ~70 million people.
- Hadrian: Pulled back. Built the Wall across northern Britain. Drew a line and meant it.
- The Pantheon (c. 126 AD): Largest unreinforced concrete dome ever built. Still standing, still working.
- The Five Good Emperors &mdash; Nerva to Marcus Aurelius &mdash; chose successors by adoption, not blood.

### Slide 8: The Engineers' Empire

- Ingenium Rōmānum
- Roads: ~400,000 km, of which 80,500 paved. Designed for the speed of a courier. Omnēs viae Rōmam dūcunt.
- Aqueducts: 11 served the city alone. Some still flow. The Pont du Gard has stood 2,000 years.
- Concrete: opus caementicium &mdash; volcanic ash + lime + seawater. It cures harder over centuries.
- The Legion: ~5,000 men, drilled to the point where battles were the easy part. They built the roads they marched on.

### Slide 9: The Crisis of the Third Century

- 235 &mdash; 284 AD
- For half a century the empire nearly came apart. Roughly fifty emperors in fifty years; most died by the sword of their own troops. The currency collapsed. Plague. Inflation. Frontier breaches on every border.
- Generals' Anarchy
- Legions made and unmade emperors as a matter of pay raises.
- Breakaway States
- Gallic Empire in the west. Palmyrene Empire under Zenobia in the east. For a decade, three Romes.
- Debasement
- The silver denarius lost ~95% of its silver content. Trade reverted to barter in places.
- That Rome survived at all is the surprise. It did &mdash; transformed.

### Slide 10: Reform, Faith, a New Capital

- 284 &mdash; 337 AD
- Diocletian
- The Tetrarchy: two senior Augustī, two junior Caesarēs. Empire too big for one man.
- Price edicts, tax reform, a hardened bureaucracy.
- The last great persecution of Christians.
- Constantine
- 312: Battle of the Milvian Bridge. "In hōc signō vincēs."
- 313: Edict of Milan &mdash; toleration of Christianity.
- 325: Council of Nicaea defines orthodox doctrine.
- 330: Founds Constantinople &mdash; New Rome on the Bosphorus.
- Two reformers bought the empire two more centuries in the west, and a thousand more in the east.

### Slide 11: Sack & Deposition

- 410 &mdash; 476 AD &middot; The Fall in the West
- 378: Emperor Valens dies at Adrianople &mdash; a Roman emperor killed by Goths in pitched battle. The frontiers are no longer holding.
- 410: Alaric and the Visigoths sack Rome itself. The city had not been taken in 800 years. Jerome wept in his cell in Bethlehem.
- 455: Vandal sack &mdash; longer, more thorough.
- 476: The Germanic general Odoacer deposes a teenage emperor named &mdash; with mythic symmetry &mdash; Romulus Augustulus. He sends the imperial regalia to Constantinople. There is no longer a Western emperor to send them to.
- "The decline of Rome was the natural and inevitable effect of immoderate greatness." &mdash; Edward Gibbon
- In the east, the empire continues. They keep calling themselves Rōmaîoi &mdash; Romans &mdash; for another thousand years, until 1453.

### Slide 12: What Rome Left Behind

- Hērēditās
- Law
- Justinian's Corpus Iūris Cīvīlis is the trunk of every European civil-law tradition. Habeas corpus, contract, property &mdash; Roman scaffolding.
- Language
- Latin became Italian, Spanish, French, Portuguese, Romanian. Half the English dictionary still arrives via Latin or French.
- Infrastructure
- Roads still followed in modern motorways. The week. The calendar. The senate. The republic itself, as an idea.
- The Church
- The bishop of Rome inherited the city's prestige. Latin liturgy preserved Roman texts through the long medieval night.
- Architecture
- Domes, arches, concrete. Every capitol building, every triumphal arch, is a quotation.
- The Idea
- "Rome" became the word every later empire wanted to claim &mdash; Holy, Russian, Ottoman, American. They are all arguing with the same ghost.
