TOP 10 BEST ROMAN EMPERORS (SPECIAL MENTION)
(11) VESPASIAN – FLAVIAN DYNASTY
(1 JULY 69 – 23 JUNE 79 AD: 9 YEARS 11 MONTHS 22 DAYS)
Founder of the Flavian dynasty and restorer of the Pax Romana from the civil war of succession in the first century.
(12) CLADIUS – JULIO-CLAUDIAN DYNASTY
(24 JANUARY 41 AD – 13 OCTOBER 54 AD: 13 YEARS 8 MONTHS 19 DAYS)
“Such was life for Uncle Claudius”.
Turned the empire around after inheriting it from its worst emperor – an able and efficient administrator, above all restoring the empire’s finances.
(13) DOMITIAN – FLAVIAN DYNASTY
(14 SEPTEMBER 81 AD – 18 SEPTEMBER 96 AD: 15 YEARS 4 DAYS)
Modern historians have increasingly seen Domitian’s reign as laying the foundation of the golden age that immediately succeeded him (or at least did via a brief interregnum via Nerva). His reign was distinctive or even unique for its economic success, above all in revaluing the currency. Whether or not as per Spectrum he “was the only emperor to have actually fixed the problem of inflation, the only one”, he certainly “maintained the Roman currency at a standard it would never again achieve”.
(14) TIBERIUS – JULIO-CLAUDIAN DYNASTY
(17 SEPTEMBER 14 – 16 MARCH 37 AD: 22 YEARS 5 MONTHS 17 DAYS)
Successor to Augustus – consolidated the empire and left the imperial treasury in huge surplus.
(15) ANTONINUS PIUS – NERVA-ANTONINE DYNASTY / FIVE GOOD EMPERORS
(10 JULY 138 AD – 7 MARCH 161 AD: 22 YEARS 7 MONTHS 25 DAYS)
My man Tony Pius, the man who maxed the pax of the Pax Romana – “His reign was the most peaceful in the entire history of the Principate” – which I would hazard to guess makes it the most peaceful in the entire history of the classical empire, given how much less peaceful the Dominate was.
(16) MARCIAN – THEODOSIAN DYNASTY: EASTERN EMPIRE
(25 AUGUST 450 AD – 27 JANUARY 457 AD: 6 YEARS 5 MONTHS 2 DAYS)
Sadly overlooked and underrated among Roman emperors – except among sources from the eastern Roman empire, with his reign often looked back on as a golden age and the people of Constantinople shouting “Reign like Marcian!” at the accession of subsequent emperors.
Took on the Huns in their own heartland – “Marcian secured the Eastern Empire both politically and financially”, and left the treasury with a surplus, reversing its near bankruptcy in which it had been when he acceded to the throne.
(17) CONSTANTIUS III – THEODOSIAN DYNASTY: WESTERN EMPIRE
(8 FEBRUARY – 2 SEPTEMBER 421 AD: 6 MONTHS 25 DAYS)
An emperor who should be ranked highly for his achievement in stabilizing the fifth century western empire, an achievement that would have been more enduring but for his short reign, truncated by illness.
(18) CLAUDIUS II / CLAUDIUS GOTHICUS – NON-DYNASTIC / CRISIS OF THE THIRD CENTURY
(SEPTEMBER 268 AD – AUGUST 270 AD: 1 YEAR 11 MONTHS)
The first of the so-called Illyrian emperors who renewed and led the Roman empire – turned the tide on the Crisis of the Third Century, laying the foundations for Aurelian and Probus to restore the empire, particularly by the victory of his title against the Goths, “one of the greatest in the history of Roman arms”.
(19) CONSTANTIUS – NON-DYNASTIC / TETRARCHY: WESTERN EMPIRE
(1 MAY 305 AD – 25 JULY 306 AD: 1 YEAR 2 MONTHS 24 DAYS)
Constantius might well have ranked higher but for his short reign as augustus or senior emperor in the West – the capstone of achievements as junior emperor or caesar for over 12 years from 293 AD, defeating the Carausian Revolt and Germanic tribes at the Rhine.
(20) TITUS – FLAVIAN DYNASTY
(24 JUNE 79 AD – 13 SEPTEMBER 81 AD: 2 YEARS 2 MONTHS 20 DAYS)
Built on the achievements of his father Vespasian – literally building in the case of completing the Colosseum, the achievement for which he is best known as emperor, and figuratively, coinciding with his most outstanding achievement being prior to his imperial accession, winning decisive victory in the First Jewish War.
And yes – I’ve shuffled those special mention entries from my original ranking, notably upgrading Constantius II after reading Peter Heather’s The Fall of the Roman Empire.
B-TIER (HIGH TIER)
And now we come to some special mention matched pairings, in which one emperor is similar to or echoed by another emperor in the Crisis of the Third Century – also while good, drop down a tier from top-tier to high-tier, often coinciding with a mixed or even negative reputation.
(21) CONSTANTIUS II – CONSTANTINIAN DYNASTY: EASTERN EMPIRE THEN WHOLE EMPIRE
(9 SEPTEMBER 337 AD – 3 NOVEMBER 361 AD: 24 YEARS 1 MONTH 25 DAYS)
(22) GALLIENUS – NON-DYNASTIC / CRISIS OF THE THIRD CENTURY:
WESTERN EMPIRE THEN WHOLE EMPIRE
(SEPTEMBER 253 AD – SEPTEMBER 268 AD: 15 YEARS)
Two beleagured emperors who holding the line of the empire during their reigns.
Constantius II has a mixed reputation but deserves his place among the good emperors for holding the empire together for almost two and a half decades – despite his brothers fighting each other, usurpers, civil war, and Germanic barbarian tribes, all while waging war with the Persian Sassanid empire for most of his reign.
Gallienus was the Crisis counterpart of Constantius II – holding the line as the empire faced “disease rampant, endless barbarian invasions, entire provinces seceding, and God knows how many usurpers”.
(23) LUCIUS VERUS – NERVA-ANTONINE DYNASTY / FIVE GOOD EMPERORS
(7 MARCH 161 AD – JANUARY / FEBRUARY 169 AD: 7 YEARS 11 MONTHS)
(24) CARUS – NON-DYNASTIC / CRISIS OF THE THIRD CENTURY
(SEPTEMBER 282 AD – JULY / AUGUST 283 AD: 10 MONTHS)
Two emperors who won impressive victories against the successive Persian empires, Parthians and Sassanids.
Lucius Verus – the mad lad or party boy adoptive brother and co-emperor of Marcus Aurelian everyone forgets about when they talk about the Five Good Emperors. “Meditate this, Marcus!” Led the Romans to victories over the Parthians, regaining control in Armenia and territory in Mesopotamia as well as sacking the Parthian royal city of Ctesiphon.
Carus – Crisis of the Third Century counterpart mirroring Lucius Verus, arguably outdoing Lucius’ Parthian War as the active leader of a campaign by an empire still recovering from the nadir of the Crisis of the Third Century against the tougher Sassanids, again sacking the Persian royal city of Ctesiphon.
(25) JULIAN – CONSTANTINIAN DYNASTY
(3 NOVEMBER 361 AD – 26 JUNE 363 AD: 1 YEAR 7 MONTHS 23 DAYS)
(26) VALERIAN – NON-DYNASTIC / CRISIS OF THE THIRD CENTURY: EASTERN EMPIRE
(SEPTEMBER 253 AD – JUNE 260 AD: 6 YEARS 9 MONTHS)
Two emperors with impressive achievements, particularly in the military field prior to their accession, but undone by defeat against the Persians.
Julian – “Thou has conquered, Galilean”. The Apostate or the Philosopher, reflecting his attempted revival of classical paganism.
Valerian – Crisis of the Third Century counterpart to Julian, similar in that his reign has also been defined by his defeat by the Sassanid Persians, although unlike Julian he was captured rather than mortally wounded in battle.
(27) NERVA – NERVA-ANTONINE / FIVE GOOD EMPERORS
(18 SEPTEMBER 96 AD – 27 JANUARY 98 AD: 1 YEAR 4 MONTHS 9 DAYS)
(28) TACITUS –
NON-DYNASTIC / CRISIS OF THE THIRD CENTURY
(DECEMBER 275 AD – JUNE 276 AD: 7 MONTHS)
Nerva – the first (and least) of the Five Good Emperors. Yes, his only real achievement might have been ensuring the peaceful transition to a good successor, but that’s still an impressive achievement, given how many Roman emperors screwed even that up.
Tacitus – no, not the historian that everyone knows when they hear the name, but Crisis counterpart of Nerva. Both were essentially (elderly) senatorial caretaker or placeholder emperors, enabling the stable succession of imperial authority from an assassinated predecessor.
C-TIER (MID-TIER)
MY PERTINAX-THRAX LINE SEPARATING GOOD FROM BAD EMPERORS
(29) PERTINAX – NON-DYNASTIC / YEAR OF FIVE EMPERORS
(1 JANUARY – 28 MARCH 193 AD: 2 MONTHS 27 DAYS)
(30) MAXIMINUS THRAX –
NON-DYNASTIC / CRISIS OF THE THIRD CENTURY
(MARCH 235 AD – JUNE 238 AD: 3 YEARS 3 MONTHS)
Poor Pertinax – he essentially tried to pull off a Nerva, but was unlucky to be faced with a more aggressive and frankly out of control Praetorian Guard. Indeed, in terms of his brief administration, he was better than Nerva, particularly in financial reform, but just didn’t get the same chance Nerva did.
Maximinus Thrax – archetypal barracks emperor, who secured the German frontier of the empire, at least for a while.
TOP 10 BEST ROMAN EMPERORS (HONORABLE MENTION)
ULPIA SEVERINA – FIRST AND LAST EMPRESS OF THE CLASSICAL ROMAN EMPIRE
(275 AD: 5-11 WEEKS – 6 MONTHS?)
I’m not giving her a numbered ranking since her ‘reign’ as widow of Aurelian really boils down to a few coins minted in her name (and she does not appear in the Wikipedia list of Roman emperors accordingly).
However, I’ll just leave her here as I like the romantic speculation of her as first and last empress of the classical Roman Empire.
(31) VETRANIO – USURPER: CONSTANTINIAN DYNASTY (WESTERN EMPIRE)
(1 MARCH – 25 DECEMBER 350 AD: 9 MONTHS 24 DAYS)
One of three good usurpers of the classical Roman empire – counter-usurper against another usurper (Magnentius), abandoning his claim when meeting Constantius II and earning himself peaceful retirement
MY PERTINAX-THRAX LINE…OR IS THAT MY EUGENIUS-JOHANNES LINE SEPARATING GOOD USURPERS FROM BAD EMPERORS?
(32) EUGENIUS – USURPER: VALENTINIAN DYNASTY (WESTERN EMPIRE)
(22 AUGUST 392 AD – 6 SEPTEMBER 394 AD: 2 YEARS 15 DAYS)
One of the great what-ifs of the late Roman empire – that the western empire would have fared better or at least stalled its fall longer if he and military commander Arbogast had won the Battle of the Frigidus in 394 AD. Or even better, if they had not fought it at all, with the eastern emperor Theodosius recognizing Eugenius as western emperor instead. At very least, the western empire would have been spared Honorius.
(33) JOHANNES – USURPER: THEODOSIAN DYNASTY (WESTERN EMPIRE)
(20 NOVEMBER 423 AD – MAY 425 AD: 1 YEAR 6 MONTHS)
If Eugenius would have spared the western empire Honorius, Johannes would have spared it Valentinian III.
