Europe, 1490. While Leonardo da Vinci sketches flying machines in Milan and Christopher Columbus prepares to sail west, a more practical revolution is unfolding in the mountains north of Bergamo. An Italian family of courier merchants is about to corner the market on something more valuable than gold: information.

Their name is Tasso—Italian for "badger," the animal on their family crest. They're courier merchants, nothing more. But they're about to build something that will outlast kingdoms.

This is a Renaissance story you might not have encountered—the one where logistics mattered as much as art, where a family business became indispensable to emperors, and where controlling the infrastructure of communication turned out to be more valuable than owning land.

To understand why the Tasso family mattered, you need to understand the magnificent disaster they were working with: the Holy Roman Empire.

In 1490, the "Empire" was neither holy, nor Roman, nor much of an empire. It was a bureaucratic fever dream—somewhere between 300 and 350 separate political entities stretched from the Netherlands to Bohemia, from the Baltic to the Alps. Prince-bishoprics. Free imperial cities. Principalities smaller than a modern suburb. The Prince-Abbot of Kempten ruled territory you could walk across in an afternoon. The Free City of Frankfurt answered to no one but the Emperor—who had almost no actual power.

The Empire called itself "Roman" because it claimed to be the successor to the ancient Roman Empire, revived when Pope Leo III crowned Charlemagne "Emperor of the Romans" in 800 AD. But by 1490, that Roman legacy was pure mythology. The emperors were German-speaking rulers elected by German prince-electors, governing primarily Germanic territories. The title "Holy Roman Empire of the German Nation" wouldn't be formalized until 1512, but everyone already understood what it really was: a German confederation pretending to be Rome reborn.

There was no central army, no unified tax system, no imperial bureaucracy that functioned beyond the Emperor's own hereditary lands. The Papacy had spent centuries deliberately sabotaging any attempt at imperial consolidation, terrified that a strong German emperor might challenge Rome. While France and England were building centralized nation-states with actual governments, the Holy Roman Empire remained a patchwork held together by legal fiction and Habsburg ambition.

This was the Renaissance—Gutenberg had invented the printing press in 1440, ideas were spreading faster than ever, trade was booming, banking houses like the Medici and Fuggers were financing kingdoms. But if you were Emperor and needed to send a message from Vienna to Brussels? You hired a guy and hoped he didn't get murdered by bandits.

Communication across this fragmented empire was chaos. And chaos meant opportunity.

The Tasso family came from Cornello, a mountain village in the Val Brembana north of Bergamo, in Lombardy—what's now northern Italy but was then a constantly shifting battlefield between city-states, the Holy Roman Empire, and anyone else with an army.

Around 1290, as Milan and Bergamo tore each other apart in the Guelph-Ghibelline wars (the pro-Pope faction versus the pro-Emperor faction, because medieval Italy loved a good family feud), a man named Omodeo Tasso made a smart bet. He gathered 32 relatives and organized them into the Compagnia dei Corrieri—the Company of Couriers. They created coordinated routes linking Milan, Venice, and Rome.

This wasn't revolutionary. The Roman Empire had its Cursus Publicus—the imperial postal system with relay stations, fresh horses, couriers carrying the Emperor's seal. Mongol khans had built the Yam, an even more terrifying network where riders carrying bronze paizas (authority tablets) could requisition anything they needed and covered 200+ miles a day. Miss your delivery window? Execution.

Both systems collapsed with their empires. What the Tassos did differently was make it commercial. They didn't serve one emperor—they served anyone who could pay. Their riders became so reliable that across Italy, people called fast messengers bergamaschi—"those Bergamo guys."

By 1443, one of them—Ruggiero de Tassis—caught the attention of Holy Roman Emperor Frederick III. Ruggiero reorganized his family operation to serve the Empire, linking Bergamo to Vienna by 1450, then adding routes to Innsbruck, Brussels. The family was moving north, following Habsburg power, transforming from Italian merchants into European infrastructure.

But the real breakthrough came in 1490, when Franz von Taxis (the family name now Germanized from "Tasso" to "Taxis") made an offer to Emperor Maximilian I that changed everything.

Maximilian I had a problem that perfectly illustrated the Renaissance. The printing press was spreading information faster than ever—but only within cities. Between cities? Still medieval. Maximilian had recently married Mary of Burgundy, inheriting the wealthy Netherlands. The Habsburg domains now stretched from Austria to Flanders to Spain, a discontiguous empire held together by dynastic marriage and constantly threatened by France, the Ottomans, and internal rebellion.

He needed coordination. Intelligence. Speed. He needed to know what his governors were doing before they became problems.

Franz von Taxis promised him something impossible: letters delivered from Innsbruck to Brussels in five and a half days. Guaranteed delivery times. Scheduled routes. The Habsburg communication problem solved.

The method was Roman: relay stations with fresh horses every 15-20 miles. Riders carried post horns—distinctive curved brass instruments they'd blow as they approached each station, alerting stable hands to have a fresh mount saddled. The rider would dismount, transfer his felleisen (an iron-reinforced leather satchel chained to his wrist), and be gone within minutes. The letter never stopped moving.

Compare this to the Mongol Yam's 25-mile relay stations, or the Pony Express 370 years later with its dramatic 10-mile sprints. The Tassos weren't trying to break speed records—they were building reliability. You could plan around their schedules. Merchants could time their business correspondence. Diplomats could coordinate negotiations. Military commanders could synchronize troop movements. You could respond to crises before they spiraled.

In 1505, Franz von Taxis was named Imperial Postmaster General with a monopoly on carrying royal mail. This is where the story gets interesting—because in 1506, they opened the service to private customers.

Suddenly, merchants could send contracts across Europe on predictable schedules. Bankers could coordinate trades. Scholars could exchange letters. The Venetian merchant networks had done something similar in the Mediterranean, using trading houses as communication nodes, but those were informal and fragmented. The Taxis network was systematic—standardized rates, published timetables, guaranteed service.

In 1516, when Maximilian's grandson Charles V inherited both the Spanish throne and the Habsburg domains, creating an empire so vast that it literally spanned the globe—from the Americas to the Philippines—the Taxis network expanded accordingly. They established the Brussels-to-Spain route. They connected Prague. They reached Naples.

By the mid-1500s, the family's postal network was the only pan-European institution that actually functioned. In an empire with no unified government, they were the nervous system.

And like any nervous system, they knew everything.

Here's where the story gets dark—and remarkably modern.

The Taxis family maintained Geheime Kabinette—secret cabinets, or what the French called cabinets noirs and the English called "black chambers." These were specialized offices where government-employed experts would intercept mail, open it, copy or decode it, and reseal it before delivery.

The technique was sophisticated. By 7 AM, letters destined for foreign embassies in Vienna would be redirected to the black chamber in the Hofburg Palace. Teams worked with industrial precision:

The seal forgers would carefully heat wax seals with special tools, softening them just enough to peel away without breaking. They'd make impressions in clay or special wax to create duplicate stamps. This was delicate work—break the seal and the recipient knows their mail was compromised.

The copyists would transcribe the letter's contents, working at speed. Important letters might be fully copied; others just summarized.

The cryptanalysts would tackle coded correspondence. By the 18th century, teams of specialists worked together cracking monoalphabetic ciphers—the kind where each letter is replaced by another letter or symbol. They'd use frequency analysis (the letter 'E' appears most often in most languages), pattern recognition, educated guessing based on diplomatic context.

The resealing team would fold the letters back precisely, apply fresh wax using the forged seals, and ensure no visible signs of tampering. Some became so skilled they could open and reseal a letter in under ten minutes.

And when diplomatic correspondence became sensitive enough to require secrecy, people adapted. Invisible inks became an arms race. Writers used solutions made from ferrous sulfate and water (iron compounds dissolved to create messages that appeared blank until treated with chemicals), lemon juice, milk, even artichoke juice—all of which would write invisibly and only appear when heated or treated with specific reagents. The alum-based invisible ink developed by William Gregory in the 1570s required revealing with a specific chemical wash—just holding it over a candle wouldn't work.

Diplomatic correspondence filled with elaborate ciphers. Writers developed numerical codes where numbers replaced words based on agreed-upon dictionaries—you'd need the exact same edition of a specific book to decode the message. Some letters used mask ciphers—you'd write a normal letter, but place a special cutout sheet with windows over it to reveal the real message hidden in specific words.

The Taxis network handled all of this traffic. And here's the critical question: did people know their mail was being opened?

The answer is complicated. Diplomatic correspondence sent through the Brussels black chamber run by Alexandrine of Taxis was opened systematically, with letters copied and resealed within a couple of hours—and diplomats absolutely knew this was happening. It was an open secret. Foreign embassies assumed their letters would be read and encrypted accordingly.

But what about private citizens and merchants who paid hefty fees—the equivalent of a day's wages—to send letters? The evidence suggests the family was selective. Black chambers opened "suspicious" letters, which likely meant correspondence that could yield valuable intelligence or involved politically sensitive figures. Routine merchant correspondence about wool shipments or family letters probably passed through unmolested—there simply wasn't enough value or manpower to read everything.

The Habsburgs explicitly authorized this arrangement. The family's monopoly came with an implicit understanding: they would provide intelligence to the Emperor. Other European powers accepted it too and some sources claim Alexandrine sold information to the highest bidder, while others claim she worked for both Emperor Ferdinand II and his successor Ferdinand III. The French started their own Cabinet Noir in 1590. The British established a black chamber in the Post Office by 1732.

Everyone was doing it. Privacy wasn't a right—it was something you negotiated through increasingly sophisticated encryption. The Taxis family just happened to control the choke point where all that encrypted traffic passed through.

Think about what this meant in practice. The Taxis family knew who was corresponding with whom. They knew about trade negotiations before governments did. Military movements. Secret alliances. Personal scandals. They were simultaneously Europe's postal service, its intelligence network, and its information marketplace.

Sound familiar? Because this is exactly what we argue about today—except instead of steamed-open letters, it's encrypted messaging apps and government backdoors.

The difference is we pretend to be shocked when we learn intelligence agencies read our communications. In the 1600s, everyone knew the mail was compromised. Privacy wasn't expected—it was negotiated through increasingly complex encryption.

Compare this to the Rothschild banking family's courier network in the 1800s—they famously learned of Napoleon's defeat at Waterloo before the British government through a combination of express riders and carrier pigeons. That intelligence advantage earned them a fortune on the bond markets. The Rothschilds operated for decades. The Taxis family did the same thing for three centuries.

Now we get to the name confusion, which tells you everything about how the family transformed.

They started as Tasso—Italian, meaning "badger." When they moved north and began serving the Habsburg court, the name became Tassis (Latin form) or de Taxis (German variant). Same family, different linguistic contexts. Italians becoming German. Merchants becoming nobility.

In 1608, the Brussels branch of the family was elevated to hereditary barons. In 1624, they became counts. But here's where it gets delicious: when you're trying to become princes in a society obsessed with ancient lineage, being descendants of courier merchants isn't impressive enough.

So in 1650, Alexandrine von Taxis—one of the first female CEOs in European history, running the postal empire after her husband's death in 1628—commissioned genealogists to "clarify" the family origins. These genealogists made a remarkable "discovery": the Tassos weren't just merchants! They descended from the Della Torre family (Torriani), who had ruled Milan and Lombardy until 1311!

Was there documentary evidence? No. Did anyone believe it? Probably not. Did it matter? No—because Alexandrine successfully petitioned Emperor Ferdinand III for a name change in 1650.

Torre (Italian for "tower") became Thurn (old German for tower). Tasso (badger) became Taxis (German variant). The family was now Thurn und Taxis—Tower and Badger. Their coat of arms now featured both the tower from the (possibly fictional) Della Torre lineage and the badger from their actual merchant past.

In 1681, they achieved princely rank in the Spanish Netherlands. In 1695, Emperor Leopold I elevated them to Imperial Princes of the Holy Roman Empire—Fürstenhaus, First House. They were now princes without territory, "briefadel" (letter nobility), elevated purely for service rather than land ownership.

Think about this trajectory: In 1290, they were Italian couriers fleeing civil war. By 1695, they were Imperial Princes of the Holy Roman Empire. Not through conquest, not through marriage—through logistics. They built infrastructure, and infrastructure became power.

Consider the contrast with America's most romanticized postal venture: the Pony Express.

The Pony Express operated from April 1860 to October 1861. Eighteen months. It was a spectacular financial disaster, required military protection against hostile territory, and became obsolete the moment the transcontinental telegraph was completed. It exists now primarily in Western films.

The Thurn und Taxis postal system lasted 377 years. From 1490 to 1867. It survived:

Why the difference?

The Pony Express was nationalist—linking California to the Union during mounting sectional crisis. Its purpose was political, temporary, and expensive. It served a single government with a specific short-term goal.

The Thurn und Taxis empire was transnational. They didn't serve nations—they served the network. They carried mail for emperors, revolutionaries, merchants, and spies. When borders changed, they adapted. When technologies improved, they integrated them—adding stagecoaches, riverboats, early railways. When the Holy Roman Empire dissolved in 1806, they pivoted to serving the German successor states.

Their loyalty wasn't to politics—it was to infrastructure. And infrastructure transcends individual regimes.

This is also why they outlasted the Roman Cursus Publicus (which collapsed with the Western Roman Empire around 476 AD) and the Mongol Yam (which fragmented with the Mongol Empire's decline in the 14th century). Those were imperial systems—they lived and died with their empires. The Thurn und Taxis system was something stranger: a private company operating with imperial monopoly, flexible enough to survive political chaos.

In 1748, when Emperor Franz I appointed Prince Alexander Ferdinand as Principal Commissioner (the Emperor's representative) at the Perpetual Diet in Regensburg, the family moved their entire court there. The Perpetual Diet—formally the Immerwährender Reichstag—was the Holy Roman Empire's permanent parliament that had been in continuous session in Regensburg since 1663. (The word "diet" comes from Medieval Latin dieta, meaning "assembly.") Unlike earlier diets that met occasionally and disbanded, this one never adjourned, remaining in session for 143 years until the Empire's dissolution in 1806. By becoming the Emperor's official representative to this assembly, the Thurn und Taxis family embedded themselves at the very center of imperial governance. They brought culture, wealth, patronage. The Bohemian-Austrian poet Rainer Maria Rilke—one of the most important modernist poets of the early 20th century—would later write his Duino Elegies while staying as a guest of Princess Marie von Thurn und Taxis at Duino Castle near Trieste. They transformed from postal administrators into aristocratic fixtures.

They weren't just delivering mail anymore. They were the establishment.

By the 19th century, the problem was obvious to anyone paying attention.

Nation-states were consolidating. Germany was unifying under Prussian leadership. The age of fragmented medieval empires was ending. And governments were looking at the Thurn und Taxis monopoly and asking an uncomfortable question:

Why is a private family controlling our national communications infrastructure?

The Holy Roman Empire's dissolution in 1806 had already stripped them of their imperial monopoly. They pivoted to operating across the German successor states—Bavaria, Württemberg, Baden, Hesse, the Rhineland. They even started issuing their own postage stamps in 1852, after the innovation spread from Britain.

But Prussia was consolidating power. In 1866, the Seven Weeks' War saw Prussian troops occupy Frankfurt, where the Thurn und Taxis headquarters was located. For a private postal company trying to maintain operations across a fragmenting Germany, having your headquarters under military occupation by the very power consolidating German unification was ominous. Prussia was clearly building a unified German state—and unified states don't tolerate private families controlling national infrastructure.

In 1867, the family sold their entire postal operation to the Prussian government for three million thalers—roughly $350 million in today's money. They used the proceeds to buy castles, breweries, forests, and art collections. They remained at St. Emmeram Castle in Regensburg, where they'd been based since 1803.

The age of the national post office had arrived. Every major European power now understood what Rome, the Mongols, and the Habsburgs had always known: whoever controls the mail controls power. And that power was too important to leave in private hands.

The Thurn und Taxis family didn't disappear, though. They just became what old money becomes: patrons of culture, fixtures of aristocratic society, holders of vast inherited wealth. Today they're one of Germany's richest families. The current head is Albert, 12th Prince of Thurn and Taxis.

Most people have never heard of them. Which is remarkable, considering they ran Europe's communications for 377 years.

Strip away the horses and wax seals and look at what actually happened:

Does this sound familiar? Because we're having the exact same argument about tech platforms right now.

In 1650, people complained about the Thurn und Taxis family reading their letters. Today we complain about tech companies reading our data. The tools change. The dynamic doesn't.

The Hanseatic League understood this in the 1400s with their merchant-messenger system linking trading posts from London to Novgorod—whoever controlled communication between autonomous cities controlled trade itself.

The Dutch and British East India Companies built global networks of ships acting as communication relays in the 1600s. They operated like private governments, much like the Thurn und Taxis acted as the mail system of the Holy Roman Empire.

Even the "Black Dispatch" networks during the American Civil War—semi-official, privately managed courier routes run by Union and Confederate intelligence—operated on the same principle: trusted couriers, fragmented territories, logistics as espionage.

The lesson isn't that history repeats. It's that infrastructure is always political. Communication infrastructure especially. Whether it's Roman roads, Mongol relay stations, courier networks, postal services, telegraph lines, telephone systems, or internet platforms—whoever builds the roads that information travels on doesn't just provide a service. They shape what's possible to know, who can know it, and how fast it spreads.

The Von Thurn und Taxis understood this in 1490. They built the roads information traveled on. They charged fees for using those roads—not physical tolls on highways, but postal rates for guaranteed delivery. They monitored the traffic flowing through their network. For 377 years, they were more important than most kings—precisely because kings depended on them.

Then nation-states caught up, built their own postal systems, and made infrastructure a sovereign function. The family got rich and faded into aristocratic obscurity.

We're living through a similar moment now. The arguments about whether private companies should control data infrastructure, cloud computing, social media networks, and payment systems echo the 19th-century realization that families shouldn't control the mail.

History suggests an endpoint: the state eventually takes over. But the pattern also reveals who wins. The Thurn und Taxis family walked away with three million thalers in 1867—roughly $350 million in today's money. They're still one of Germany's wealthiest families. The current Prince of Thurn und Taxis lives in a palace with 500 rooms.

Infrastructure always becomes too important to leave in private hands. But by the time the state realizes this, the private operators have already extracted enough wealth to remain powerful indefinitely—just in different ways.

The family that ran Europe's mail for 377 years still exists. They just don't need to work anymore.
