Byzantine Empire in 1337

ANDRONIKOS III PALAIOLOGOS — THE LAST SOLDIER-EMPEROR

The empire of the Romans is a thousand years old and shrinking by the season, but its young emperor refuses to preside over a museum. Andronikos III, who won his throne in a civil war against his own grandfather, campaigns in person with his brilliant friend and Grand Domestic John Kantakouzenos ever at his side — this very year their armies bring Epirus back under the double-headed eagle, the empire’s last real reconquest. Yet across the straits the news is all ruin: Nicomedia, the final Roman city in Bithynia, is falling to the emir Orhan, and Anatolia — the empire’s ancient heartland — is gone for good. Andronikos is energetic, beloved by his soldiers, and has a young son. Can the Palaiologoi trade a lost Asia for a rebuilt Greece before the money runs out? Or will the friendship between emperor and Grand Domestic — the empire’s greatest asset — curdle, in the hands of their heirs, into the civil war that finishes what the Fourth Crusade began?

TL;DR

The Byzantine Empire is what you get when the Roman Empire doesn’t fall, but gets a major rebrand. It’s the eastern half that survived the “Barbarian DLC” of the 5th century¹. They called themselves Romans², their Emperor was the Basileus Rhōmaíōn, and for a thousand years, they considered themselves the defenders of Christendom and the keepers of classical knowledge.

Emperor Justinian I tried to reboot the whole Roman server in the 6th century by reconquering Italy and North Africa, but the empire was better at defense than offense. Its history is a 1000-year-long saga of fighting Persians, Arabs, Slavs, Bulgars, and eventually, its own “allies”—the Western Crusaders, who sacked Constantinople in 1204 in the biggest “friendly fire” incident in history. The empire limped on for another 250 years before the Ottomans brought their big cannons in 1453 and ended the series for good.

Roman, or Greek?

A core debate and common confusion about the Byzantium is, were they Roman or Greek? While they proudly identified as Romans, their culture and language increasingly shifted towards Greek influences, creating a unique synthesis.

The Imperial Firewall: Eunuchs in Power

The Byzantine court had a unique solution to the problem of ambitious men seeking the throne: create a class of “men” who legally couldn’t. Eunuchs were the ultimate imperial civil service. Unable to produce heirs and start their own dynasty, they were considered the “safest” people to have in position of extreme power. Was this a feature, or a bug? It’s really hard to tell.

The Ultimate Career Ladder

For a eunuch, the glass ceiling was practically non-existent. They could rise to become:

• Parakoimomenos: The “One Who Sleeps Beside the Emperor.” The chief minister and most powerful man in the empire after the Emperor himself.
• Generals: Unlike in many other societies, Byzantine eunuchs could and did lead armies. Justinian’s brilliant general, Narses, who reconquered Italy from the Goths, was a eunuch.
• Patriarchs: They could even hold the highest religious office as the Patriarch of Constantinople. Nicetas I, a slavic eunuch, was the Patriarch of Constantinople from 766 to 780³.

East vs. East: Byzantine Eunuchs vs. Chinese Eunuchs

While both Byzantium and Chinese dynasties kept eunuchs as a necessary tool of statecraft, the political positions of eunuchs vastly differ. Chinese eunuchs very rarely hold military power, could not hold religious title (due to Confucian views on bodily integrity), and could not legitimately hold massive political power⁴. In essence, a Byzantine eunuch could become a CEO, while a Chinese eunuch was more like the Chief of Staff with a secret police budget—powerful, but in a shadowy way and more contested.

Imperial Symbolism

Born in the Purple

In the Byzantium, purple wasn’t just a color; it was a statement. It was the color of emperors, of divinity, and unbroken legitimacy. The phrase “Porphyrogenitus” (Πορφυρογέννητος), meaning “born in the purple,” wasn’t just a fancy title—it was a crucial claim to the throne (but only when you sit on the throne).

The emperors were so obsessed with purple, that a special “purple room” (the Porphyra Chamber) was designated within the imperial palace specifically for imperial births, ensuring that legitimate heirs were literally ‘born in the purple’. Even among its long history of 10 centuries, there were merely two dozens of emperors who were actually born in the room too purple to live in.

Myth vs. Reality of “Born in the Purple”

When the Byzantines said somenone was “born in the purple” they weren’t being metaphorical. The Great Palace in Constantinople had a special room, laid top to bottom with purple marble, (Porphyra in Greek) in which the Empress gave birth. So a Porphyrogenitos was someone literally born in the purple (room).

As far as your question: There were exactly three emperors in all of Byzantine history that had both porphyrogenitoi and non-porphyrogenitoi sons to choose from as successors. The first was Basil I the Macedonian. His co-emperor and designated heir for most of his reign, was his eldest non-porphyrogenitos son, Constantine. He only reluctantly made his other son, Leo, his successor after Constantine died. There was never an issue of deliberately skipping over him in favor of Leo.

The second was Constantine X Doukas. He had both, Michael who was born before he became Emperor, and Konstantios who was “born in the purple”, designated as his co-emperors. After a brief interlude when Romanos IV Diogenes ruled the Empire, Michael took over as senior emperor. Again, there was no objection due to lack of “purple” birth.

The third and most pertinent to your question is Michael VIII Palaiologos. The near-contemporary historian, Nikephoros Gregoras, mentions that Michael would have much preferred to leave the throne to his younger son, Constantine (the first porphyrogenitos in close to a century) rather than his older son, Andronikos, if only his later birth wasn’t a “great obstacle before him”. So again, being “purple born’ in no way trumps being born first.

Just one more thing in case you got you info from this wikipedia article. The source cited for the claim that “children born to reigning emperors held superior rights to the throne over siblings born before their father ascended the imperial throne” is this article. It was published in Scientific American and it is about porphyria, a “group of diseases that result from abnormal accumulations of red and purple pigments produced by the body”. The author is just being clever by titling it “Born to the Purple”. But just in case we are now getting our info on Byzantine history from articles on hematological diseases; no, the author nowhere says what wikipedia claims that he says.

So, kids, your professors aren’t just being dicks when they tell you you can’t use Wikipedia as a source. They have very, very good reasons for that.

The Double-Headed Eagle

While the single-headed eagle was the proud standard of the legions of the original Roman Empire,  the double-headed eagle became the enduring symbol of the Byzantine Empire. It wasn’t just a cool design; it was a profound statement about their identity and aspirations. After the fall of Constantinople, multiple nations and royal houses adopted the double-headed eagle on their coat of arms, most famous ones being Holy Roman Empire and Tsardom of Russia. This adoption often signified a claim to imperial succession or a desire to associate themselves with the prestige and legacy of the Roman Empire⁵.

The Byzantine Diplomacy into Distributed System

The word “Byzantine” is now a synonym for “deviously complex,” and for good reason. Surrounded by enemies, they couldn’t win by brute force alone. They mastered the art of 4D chess⁶.

• Playing the Barbarians: They would pay one tribe to attack another, then pay the survivor to go away.
• The “Wow” Factor: Foreign envoys were treated to displays of immense wealth and mechanical wonders in the palace (like roaring golden lions and rising thrones) to intimidate them into submission.
• Strategic Marriages: They would marry off princesses to powerful foreign rulers (like Anna Porphyrogenita⁷ to Vladimir of Kiev) to create alliances and spread their culture.
• The Varangian Guard: When you can’t beat the Vikings, hire them. The Emperor’s personal bodyguard was an elite force of Norsemen who were famously loyal as long as the gold kept flowing.

Job Welfare as the Basileus

The Emperor of the Romans was the most prestigious job in the medieval world, but statistics suggest it was not the best job you could find. A quick glance at the imperial succession reveals a startlingly high turnover rate, with many rulers meeting violent ends through deposition, blinding, or assassination.

The Onboarding

One good thing about Byzantium is the HR didn’t care about your year of experience. You were either too young to know what was happening or too old to remember it. Michael III ascended the throne at the tender age of two (until his favorite courier murdered him 25 years later), and Justin I didn’t even start the job until 77.

The Off-boarding

Among the 90 emperors who ruled from 330 to 1453 (depending on how you count co-emperors), the success rate for a peaceful retirement is very low. 23 of the 90 emperors met a violent end, and it just got worse in the subsequent turbulent centuries. We have two honorable mentions:

• Most Stylish Off-boarding: After the Crusaders sacked the city in 1204, Alexios V “Murtzuphlos” fled, but was eventually captured by the Latins. The decided a standard execution was too boring for a Roman Emperor. Instead, they asked him to do a leap of faith from the top of the Column of Theodosius.
• Extreme Makeover Monastery Edition: While most emperors were dragged kicking and screaming to the monastery, John VI Kantakouzenos made it a lifestyle choice. After a chaotic civil war, he abdicated and rebranded as “Monk Joasaph.” He spent his retirement writing a massive four-volume history of his own reign and becoming a celebrity theologian. It’s the ultimate 14th-century version of “quitting your corporate job to write a memoir and do yoga.”

The Most Roman Awards

The glory of Most Roman Death was given to Nikephoros I, whose skull became a drinking cup—a stark reminder that the “civilized” Romans were always one bad day away from becoming dinnerware.

Then there is Justinian II “Rhinotmetos” (the Slit-Nosed). After having his nose cut off and being exiled—which should have been a career-ender⁸—he got a prosthetic gold nose, raised a barbarian army, sneaked back into Constantinople through an aqueduct, and took his revenge.

Statistics Corner: A Data-Driven Analysis

Among the 86 universally recognized emperors (excluding brief co-emperors and usurpers for data sanity) ($N=86$):

• Lifespan: $52.0\pm16.5$ years (median: $56.0$ years)
• Reign: $12.5\pm 11.8$ years (median: $9.0$ years)
• Violent Ends: $29.4\%$ (or $32.9\%$ if you count “hunting accidents”)
  The massive standard deviation in both categories confirms the extreme occupational hazard. The brutal reality is further visualized in the following figures.

  Comparison with TTAP. Compared with the Basileus, tenure-track assistant professor (TTAP) suddenly looks like a preferable job. In academia, a harsh mid-tenure review involves a committee of senior faculty critiquing your citation index and grant funding. In Constantinople, your mid-tenure review usually involved a rogue general from Anatolia marching on the capital or the Varangian Guard deciding they didn’t like your recent budget cuts.

The “severance packages” are also vastly different:

• Academic Severance: Being denied tenure, getting a terminal year to wrap up your research, and updating your CV for the job market.
• Byzantine Severance: Forced tonsure and monastic exile, rhinokopia (nose-slitting to legally disqualify you from future rule), blinding with a red-hot poker, or a sudden, fatal “hunting accident.”

While dealing with university bureaucracy and the peer-review process is genuinely agonizing, at least your department chair isn’t going to mandate your blinding if your latest paper gets rejected by a major journal. The academic tenure track is incredibly demanding, but the occupational health and safety standards are a massive upgrade from the Roman Empire.

Trivia

• Greek Fire: The empire’s secret weapon. An ancient form of napalm that could burn on water. It was pumped through siphons. It wasn’t just a bomb; it was a flamethrower. The recipe was a state secret so well-kept that people still don’t know its exact composition today.
• They Gave Us The Fork: The fork was considered a decadent and scandalous item in the West, but it was common in the high society of Constantinople. A Byzantine princess brought it to Venice in the 11th century, and Europe slowly, very slowly, caught on.

Footnotes

1. After the fall of the Western Roman Empire in 476 CE, the Eastern half continued to thrive. And they actually lasted another 10 centuries! ↩

2. The term “Byzantine” was actually invented by a German historian in the 16th century. The empire was never called “Byzantine” by either its people or its neighbors. The formal name of the Empire was always the Roman Empire, or Basileía Rhōmaíōn in Greek. Interestingly, the term is invented by German - people of the pretenders to the Roman Empire. ↩

3. Interesting enough, Nicetas I was declared as heresy by the Second Council of Nicaea in 787 for his support of Iconoclasm (destruction of icons). ↩

4. While politically strong eunuchs in Chinese history were usually considered “corruption” and a sign of imperial decline, there were more than enough eunuchs holding huge political power in Chinese history. ↩

5. Romulus must wonder why all these barbarians claim to be his successor while obsessed with birds. ↩

6. But eventually it turns out playing 4D chess, for all its ingenuity, couldn’t always compensate for the sheer number and tenacity of their enemies. ↩

7. Anna was a “Porphyrogenita” - princess born in the purple. ↩

8. Byzantine law prohibited mutilated individuals from becoming emperor, as physical perfection was considered a prerequisite for imperial rule. ↩
