A distinct historic state, not Russia with a P: a medieval crusader conquest on the Baltic that became the Hohenzollern kingdom, led German unification in 1871, and was abolished by the Allies in 1947.

What Was Prussia?

“Happy the people whose annals are blank in history books.”
Thomas Carlyle, History of Friedrich II of Prussia

Before Germany there was Prussia. Without Prussia there would have been no Germany.

Now Prussia is simply no more.

But what on earth was this mythical land anyway?

Vox pop that question publicly now and more often than not you will be met with stunned silence – or the awkward suggestion that it might have something to do with old mother Russia – or maybe Persia.

What exactly Prussia was has always been defined by the era in which the question has been asked.

By virtue of its wildly different forms, you would receive a different definition if the question were asked in 1945, 1845, or 1745. So old is the quandary that the same could be said for 1445 and 1245. A truly European dilemma.

What can be stated with great certainty is that Prussia no longer exists. Joining the long list of fellow fallen states: Biafra, Rhodesia, Gran Colombia, Sikkim, the Zulu Kingdom, the Orange Free State…

While many of these sovereign states have disappeared into obscurity, the impact of the rise and fall of the once mighty European power of Prussia can still be felt.

Europe without Germany now would be unimaginable but Germany without Prussia would be simply inconceivable. In more than one measure of the word.

Dealing with the question of the former – there would still be the awkward alliance of Austria and Switzerland, enough to preserve the diphthongs and clunky compound nouns (see: Donaudampfschifffahrtselektrizitätenhauptbetriebswerkbauunterbeamtengesellschaft) of the language, and the measurably superior original Viennese Schnitzel.

For better or worse, Europe without Germany would be a substantially different place, but Germany without Prussia would likely have never existed.

So integral as it was to the growth and eventual unification of Germany.

From its colonial origins in the forcible Christianisation of the flatlands of the North European Plain to the height of the Hall of Mirrors in Versailles and the Prussian-led declaration of German nationhood, Prussia endured – and ensured the transition from monastic state, to Kingdom, and then Empire.

Capable of instilling fear and bringing forth admiration in equal measure, it has been dubbed the Kingdom hatched from a cannonball, the state from the sandbox of the Holy Roman Empire, and widely recognised as being responsible for the accouchement of many of the characteristics and values that are now said to be distinctly Deutsch.

Prussia gave the world not just Germany; but German philosophers, artists, and academics.

Immanuel Kant was born and spent almost his entire life in the Prussian port city of Königsberg, revolutionary firebrand Karl Marx and philosopher Friedrich Nietzsche were both Prussian-born; the brothers Alexander and Wilhelm von Humboldt; the writers E. T. A. Hoffmann, Heinrich von Kleist, and Heinrich Heine. Jacob and Wilhelm Grimm, collectors of world-famous fairy tales, would call Prussia home. As would the composers Felix Mendelssohn, Robert Schumann, and Richard Strauss. The great Romantic painter Caspar David Friedrich (1774–1840) came from Greifswald in the Prussian province of Pomerania. Without Prussia, Johann Sebastian Bach’s Brandenburg Concertos would not exist.

Whether it be the legacy of its most celebrated leader, Frederick the Great, the legends of it abnormally tall soldiers, the cultural, scientific, and social achievements the state fostered, or the poisonously fierce patriotism and pernicious militarism its fiercest critics scorn – there is much still to say about Prussia.

Catholic Cowboys Of The Wild East

“A prince … is only the first servant of the state, who is obliged to act with probity and prudence. … As the sovereign is properly the head of a family of citizens, the father of his people, he ought on all occasions to be the last refuge of the unfortunate.”
Frederick II of Prussia

The many iterations of what – at its height – was known as the Imperial Kingdom of Prussia began in the north eastern outreaches of Europe, as the Teutonic Knights, a mediaeval military religious order, forcibly Christianised one of the last remaining pagan regions on the continent.

These Catholic crusaders would establish a monastic state, gradually Germanising the region through immigration from central and western Germanic lands.

The native Old Prussian tribes that had previously inhabited this region would be gradually assimilated by the 18th century when their language also became practically extinct.

The term Prussian – derived from the term Prūsas meaning ‘body of water’ – would, however, live on in the name given to the Duchy of Prussia that emerged following the decline of the Teutonic Order.

Such is the bloody irony of the period: that the Teutonic Knights would repress and destroy the culture and peoples of a land they would claim as their own. And then seeking a title for themselves, would name themselves after the region and people they have so violently subjugated.

By the 16th century, the stewardship of Prussia – sandwiched as it was between Poland, Sweden, and other regional powers – came into question. Accelerated by the gradual decline in the strength of the Teutonic Order.

Control of the duchy would be re-secured by Albert I, the head of the Teutonic Order, in 1525 only after pledging allegiance to the King of Poland – in what is often called the Prussian Homage.

Albert would also become the first European ruler to establish Lutheranism, and thus Protestantism, as the official state religion of his lands. This odd arrangement – a Protestant duchy owing fealty to Catholic Poland – set the stage for Prussia’s rise.

A member of the House of Hohenzollern royal family, Albert was a nephew of the Polish King, Sigismund I, and son of Frederick I, Margrave of Brandenburg-Ansbach. A significant connection that would play an important role in the development of Prussia.

At the time, Albert’s court was based in the city of Königsberg (now known as Kaliningrad and since 1945 a part of the Soviet Union and now the Russian Federation).

The shift to Berlin as the capital of Prussia would take another two centuries.

In 1618 the duchy fell into the hands of the Hohenzollern dynasty of Brandenburg, meaning one ambitious family now ruled both Brandenburg (a German electorate) and Prussia (a Polish fief).

Through marriage – and the extinction of the male line of succession in Prussia – the Electors of Brandenburg inherited full control of the Duchy of Prussia.

Establishing what was known as Brandenburg-Prussia.

Thus, by the 17th century, the “cowboys” of the Teutonic Order had given way to princely statesmen.

The union of Brandenburg and Prussia created a powerful Brandenburg-Prussia bloc, the nucleus from which a modern Protestant power would emerge.

It also planted the seed of German nationalism in the region – as Germanic culture and the Protestant faith took root in Prussia, the stage was set for this frontier land to identify itself with the wider German nation in the centuries to come.

Although, at the time, the resulting state still consisted of geographically disconnected territories in Prussia, Brandenburg, and the Rhineland lands of Cleves and Mark.

This, however, would soon change.

As historian Christopher Clarke would note: “the Baltic territory formerly known as Ducal Prussia was no longer a mere outlying possession of the Brandenburg heartland, but a constitutive element in the new royal-electoral amalgam that would first be known as Brandenburg-Prussia, later simply as Prussia.”

The Iron Kingdom

“I wish it were night or the Prussians would come!”
Arthur Wellesley, 1st Duke of Wellington, expecting to go into battle against Napoleon Bonaparte without his Prussian allies at the Battle of Waterloo

Prussia’s meteoric rise came in the 18th century, when it was forged into Europe’s “Iron Kingdom”. In 1701, the Hohenzollern ruler crowned himself King in Prussia, elevating the duchy to a kingdom even while much of its lands remained part of the Holy Roman Empire. From that point, Prussia cultivated a famously militaristic identity.

The state was poor in natural resources, but rich in military discipline – a discipline so pronounced that one contemporary quipped, “Prussia is not a country with an army, but an army with a country.”

In-fact, the development of Prussia from this point would be intrinsically tied not only to the three successive monarchs of the 18th century (Fredrick I/Frederick William I/Frederick II) but also their distinctly different personalities.

The first, Frederick I, would usher into existence the concept of a greater, more central Prussia.
His son, Frederick I, known by his nickname ‘The Soldier King’, would place emphasis on the creation and training of a modern capable army.
While his son, Frederick II (also known as Frederick the Great), would wield this power on the battlefield. Cementing Prussia’s reputation as a major European player and military power and also his personal legacy as one of the most capable military strategists in history.

As the first Prussian King would look outwards for recognition, the second would turn his gaze inwards – gutting his father’s court of any excess expenditure, instead focusing on the development of his army, the often sadistic pleasures of his Tobacco Ministry, where the King and his cabal would gather to gossip, drink, and torment each other in almost equal measure.

Frederick William I (the ‘Soldier-King’), turned the Prussian Army into Europe’s most efficient fighting force, with iron discipline instilled in both troops and society. Soldiers drilled relentlessly, bureaucracy was organized to serve the military, and even the tall grenadiers of Potsdam (hand-picked for height) became an object of legend. Prussia’s social structure was bent toward war: the Junker nobles provided the officer corps and peasants filled the ranks, all worshipping the cult of obedience.

Frederick II, now content with the structures and state (in particular, the military) that his predecessors had established, used this foundation to engage in independent Kingship.

Proclaiming himself King of Prussia, in a symbolic break from the hierarchy of the Holy Roman Empire, fighting wars against the French, Russian and Austria-Hungarian Empire – and emerging victorious.

Thanks as much to the army he had inherited from his father as his skills as a military tactician that would earn him the title: ‘Frederick the Great’.

While an incredibly superficial estimation of the successive monarchs and their achievements and merits, it does underline the important thread in this story.

In the space of less than 100 years, Prussia grew from a sandy backwater and Ducal Province in the North of Poland to a mighty power known around the world and respected as much as it was feared.

By the year of Frederick the Great’s death, Prussia’s territory had more than doubled and it was recognized as one of the continent’s leading states.

In time, Prussia would transform itself into a leading player in European politics, a highly regarded military power, and a great supporter of the arts and sciences.

Although it would be the state’s formidable professional army that would win it the most praise – and suspicion. With Prussia located in the centre of Europe, lacking in natural boundaries and surrounded by potential enemies, the state’s military was considered especially important to Prussia’s survival and growth – with the percussive march of Prussian soldiery perhaps the most defining aspect of its existence.

While its belligerence would be highlighted, Prussia would also serve as a safe haven for people fleeing religious persecution in much the same way that the United States welcomed immigrants seeking freedom in the 19th century.

Under King Friedrich II – who ruled from 1740 until 1786 – Berlin was transformed into the centre of Enlightenment thinking in the German speaking lands.

Remarkably, this tough warrior-king was also a patron of philosophy and the arts – he corresponded with Voltaire, played the flute, and promoted religious tolerance – exemplifying the paradox of Prussia’s legacy.

Prussia came to be seen as “Europe’s Sparta,” admired and feared for its martial prowess. Its army, with crack drill and rapid-fire musket volleys, became the envy (and dread) of larger nations. Yet Prussia also championed the Enlightenment in government, pioneering merit-based civil service, compulsory education, and legal reforms. It was this blend of “iron and reason” – ruthless military efficiency coupled with modern statecraft – that made the Prussian kingdom so influential.

The early years of Prussian state-building in the 17th century and consolidation of territory would set the stage for the projections of power and achievements of the Kingdom’s inhabitants in the following century.

By the early 19th century, Prussia’s rise was complete: it had helped defeat Napoleon, gained vast new territories (including the Rhineland), and stood poised to lead the German peoples into a new era.

Resulting in a capital city full of architecture inspired by the Greek and Roman civilisations that the Prussia elites sought to emulate, world-renowned institutions of learning, and a cultural milieu to rival that in Paris, Saint Petersburg, or London.

The Making Of Germany

“Prussia is not a state with an army, but an army with a state.”
French revolutionary Mirabeau

After Napoleon’s second defeat, the German states were loosely grouped in a confederation, with Prussia and its rival Austria competing for influence.

Prussia, industrializing rapidly in the west and reforming its army, positioned itself as the champion of German unity (on its own terms).

The 19th century saw Prussia become the architect of German unification – a development that would fundamentally reshape Europe. The task fell to the Iron Chancellor, Otto von Bismarck, a master of realpolitik. Appointed Prussian minister-president in 1862, Bismarck famously declared that the great questions of the age would be settled “by iron and blood.” He promptly set about using Prussia’s military might and diplomacy to achieve what liberal nationalists had failed to: a united Germany under Prussian leadership.

Bismarck’s strategy was to unify Germany through a series of short, decisive wars

First, Prussia (in alliance with Austria) defeated Denmark in 1864, liberating the German-speaking duchies of Schleswig and Holstein.
Next, in 1866, Bismarck deliberately provoked the Austro-Prussian War – a brief conflict in which Prussia’s well-oiled war machine crushed Austria in just seven weeks. This victory shocked Europe and ousted Austrian influence from German affairs. Prussia annexed several North German states and formed the North German Confederation under its hegemony.
Finally, in 1870, Bismarck goaded France into attacking, igniting the Franco-Prussian War. Behind a facade of defending German honor, Prussia rallied the independent South German states to join the fight, and together they humiliated France at Sedan.

In the aftermath, in the glittering Hall of Mirrors at Versailles, King Wilhelm I of Prussia was proclaimed Emperor of a united Germany on January 18th 1871.

It was a Prussian triumph: the birth of the German Empire (Deutsches Kaiserreich) with Prussia at its core. Bismarck had achieved with cannons what centuries of princes and revolutionaries could not – Germany was now one nation-state.

This Prussia-led proclamation of the German Empire fell on the anniversary of the coronation of Frederick I in 1701. Emphasising the continuity in the succession of the crowning of the first Prussian King and the first German Emperor.

Prussian dominance set the tone in the new empire.

An Empire conjured into existence at the same time as Northern and Southern Italy were finally unified, a matter for which Prussia can also take a great measure of responsibility.

By the time of German Unification in 1871 – the Prussian lands made up around three-fifths of the territory of what would become known as Germany.

Amounting to around two-thirds of the population of this new mega-state.

With the Prussian capital of Berlin now the capital of the unified country and the Hohenzollern monarch both King of Prussia and German Emperor – Prussia’s König became Germany’s Kaiser.

Soon Prussian officials (like Bismarck) filled key governmental positions.

The empire’s values in many ways reflected Prussian militarism and conservatism, which created internal tensions. Southern German states, largely Catholic and more liberal, warily accepted rule by Protestant Prussia. Bismarck himself launched the Kulturkampf in the 1870s – a “culture struggle” against the Catholic Church – attempting to impose Protestant-prussian ideals, which only alienated Catholic citizens.

Moreover, Prussia’s authoritarian political culture (e.g. its three-class voting system and powerful aristocracy) left a democratic deficit in the Reich. While Germany industrialized and grew mighty, some wondered if the new state carried a “Prussian burden” – a legacy of rigid obedience and martial outlook that might cloud its future.

Nonetheless, there is no doubt that Prussia’s armies and statesmen made Germany.

The unification wars permanently altered Europe’s balance of power, and Prussia’s creation of the German Empire ushered in an era in which the new Germany – das Kaiserreich – would dominate the continent’s politics up until the First World War.

Naturally, Prussia would reap the benefits of its position, although now as a state – part of a country – rather than an independent power of its own.

That being said, Prussian dominance within the German state led many to conclude that Germany was simply an extension of Prussia power – by another name.

With the German loss of the First World War and the abdication of German Emperor Wilhelm II, Prussia was turned into a ‘Free State’. The German government seriously considered breaking up Prussia into smaller states, but eventually traditionalist sentiment prevailed and Prussia then became by far the largest state of the Weimar Republic.

Two years after Adolf Hitler and the National Socialist Party seized control of Germany, the independence of the states within the country were abolished – in fact if not in law – as power became increasingly more centralised into the hands of the Nazi Party.

The Abolition of Prussia

“Of the two classes of Prussian officer, the bull-necked and the wasp-waisted, he belonged to the second. Monocled and effete in appearance, cold and distant in manner, he concentrated with such single-mindedness on his profession that when an aide, at the end of an all-night staff ride in East Prussia, pointed out to him the beauty of the river Pregel sparkling in the rising sun, the General gave a brief, hard look and replied, ‘An unimportant obstacle.”
Barbara Tuchman, The Guns of August

Prussia’s formidable reputation as Europe’s military drillmaster proved to be a double-edged sword.

In the 20th century, after two devastating world wars, many came to blame the “Prussian spirit” for Germany’s militant nationalism.

Addressing the British Parliament on September 21st 1943, Prime Minister Winston Churchill said: “The core of Germany is Prussia… There is the source of the recurring pestilence”.

A sentiment echoed by many across Europe.

More than a mere seven letter word, Prussia had come to represent everything that was unforgivable about the Germany of the 20th century. Critics would claim to trace a clear path from the Thirty Years War to the Third Reich. The criminality of Nazi Germany reached back far into the Prussian past.

The idea took hold that Prussian militarism – with its exaltation of duty, hierarchy, and war – had paved the road to aggression and tragedy.

In 1945, as the Allies dismantled Hitler’s Third Reich, they also resolved to extinguish Prussia itself.

As historian Katja Hoyer, author of Blood and Iron, observed: “When the Allied victors of the Second World War decided to abolish Prussia as a German state in 1947, as if exercising a demon, they perpetuated the myth of the inevitability of the path from a Prussian-dominated Germany to Nazism.”

The once-mighty state had already been gutted: its heartlands in the east (East Prussia, Silesia, Pomerania) were occupied by Soviet and Polish forces and would soon be permanently severed from Germany.

But the Allies wanted a symbolic burial.

In February 1947, the Allied Control Council issued a blunt decree. “The Prussian State, which from early days has been a bearer of militarism and reaction in Germany, has de facto ceased to exist,” it declared, formally abolishing Prussia forever.

The Prussian government and its remaining institutions were dissolved and its territories reorganized into new administrative units.

After roughly 700 years, the name of Prussia was erased from the map.

This act was as much psychological as political – a conscious effort to break what was seen as the militaristic tradition of Prussianism. The Allies believed that by uprooting Prussia, they could ensure Germany would never again threaten world peace.

In reality, Prussia’s legacy is more complex than just spiked helmets and goose-steps. Historians note that Prussia also stood for efficient governance, education, and even enlightened values at times. The same Prussia that bred a stern officer corps also produced innovators in law, philosophy, and music. As Cambridge historian Christopher Clark has argued, Prussia was “far more complex” than the caricature – it had been “an exemplar of the European humanistic tradition, boasting a formidable government administration, an incorruptible civil service, and religious tolerance” alongside its military heritage.

Nevertheless, in 1947 the verdict was rendered: Prussia was to be no more.

Today, Prussia survives only in dusty history books and cultural memory.
Its former lands are divided among modern Germany, Poland, Russia, and others – a fragmented reminder of a once-unifying power.

The black eagle that once adorned Prussian flags is now a historical emblem rather than a national standard.

The German federal eagle that is featured on the wall of the Bundestag earned itself the nickname: “the fat duck”. A more disarming character.

Yet Prussia’s lingering legacy can still be felt.

When people speak of German efficiency, discipline, or even the iconic Pickelhaube helmet, they are echoing the memory of Prussia.

In the end, Prussia was a creature of its time – rising through iron and blood, shaping a nation, and then perishing in fire and rubble.

It left behind a unified Germany and a complicated reputation.

As one might say, Prussia’s body was destroyed, but its ghost lives on – in Germany’s national story, in European geopolitics, and in the cautionary tales of how power and militarism can shape history for both good and ill.

Conclusion

Prussia was not simply “Russia with a P,” but a distinct historic state and region that played a pivotal role in German history. Over the centuries, the term “Prussia” has referred to several entities.

The first was the land of the pagan Prussians on the Baltic coast, conquered in the Middle Ages by German crusaders.
The second was the powerful Kingdom of Prussia ruled by the Hohenzollern dynasty from 1701, which expanded to dominate northern Germany and lead German unification in 1871.
The third was the Free State of Prussia after 1918, a state within Weimar Germany that was subsumed by the Nazis and ultimately abolished by the Allies in 1947.

In short, Prussia evolved from a medieval frontier conquest into the driving force behind a unified German Empire.

It is often remembered for its militarism and discipline, yet it also contributed administrative efficiency and enlightened reforms to European history.
