Frederick the Great: A Life in Five Chapters

Chapter 1 · The Prince His Father Nearly Killed

Flutes, French books and a failed escape

1712 – 1740 · Berlin · Küstrin · Rheinsberg

Frederick was born in Berlin on 24 January 1712, the son of Frederick William I — the 'soldier king', who despised idleness, France, philosophy and everything his heir enjoyed. The boy preferred the flute, French literature and Latin, all of which his father banned. Beatings and public humiliations were routine and are documented in the accounts of the court.

In 1730, aged eighteen, Frederick tried to flee to England with a young officer and close friend, Hans Hermann von Katte. They were caught. The king treated it as desertion by a serving officer, and had Katte beheaded in the courtyard beneath Frederick's window, ordering him to watch; witnesses recorded that he collapsed before the blow fell. Frederick himself was imprisoned at Küstrin and stripped of his rank.

The reconciliation that followed was a submission. He was put to work in the provincial administration, learning in detail how Prussian taxation, agriculture and military supply actually functioned — an education in statecraft that no tutor could have given him. In 1733 he was married to Elisabeth Christine of Brunswick-Bevern on his father's orders; they lived apart for most of their lives.

At Rheinsberg from 1736 he had four contented years of music, reading and correspondence with Voltaire. He wrote the *Anti-Machiavel*, arguing that a ruler is the first servant of the state and that aggressive war is a crime. It was published in 1740 — months before he invaded Silesia.

Why this matters

Frederick's education under a father who tried to break him produced a ruler with both an intellectual's ideals and an absolute conviction that the state's interest overrode them.

You have met the prince who watched his friend die. What would you ask him about those years?

Ask Frederick

• “What did watching Katte's execution do to you?”
• “Why did your father hate everything you loved?”
• “What did you learn working in the provincial administration?”
• “What did you argue in the Anti-Machiavel?”
• “Were the years at Rheinsberg the happiest of your life?”

Chapter 2 · The Silesian Gamble

Seven months on the throne, and a war of choice

1740 – 1745 · Silesia · Mollwitz · Hohenfriedberg

Frederick became king on 31 May 1740. In October the Habsburg emperor Charles VI died, leaving his lands to his daughter Maria Theresa, whose succession several powers had guaranteed and now questioned. In December, without declaration or provocation, Frederick marched into Silesia — a rich, populous Habsburg province on his border.

He justified it with an ancient dynastic claim almost nobody found convincing, and later wrote with startling candour that ambition, interest and the desire to make people talk about him had decided it.

His first battle, at Mollwitz in April 1741, was nearly a disaster; Frederick was persuaded to leave the field, and his infantry won it without him. He never forgot the embarrassment and never left a battlefield again.

The invasion set off the War of the Austrian Succession, drawing in France, Britain, Bavaria and Spain. Frederick fought two wars over Silesia, winning decisively at Hohenfriedberg in 1745, and kept the province at the Treaty of Dresden. Prussia's population increased by roughly half, and it gained textile industries and mineral wealth that transformed its finances.

Maria Theresa never accepted the loss. Her determination to recover Silesia reshaped European alliances entirely: by 1756 Austria had allied with its ancient enemy France, and Prussia with Britain — the 'Diplomatic Revolution' that set up the next and far more dangerous war.

Why this matters

The seizure of Silesia is a textbook case of a war of choice: it made Prussia a great power, and it committed Frederick to defending an acquisition that nearly destroyed him.

You have seen a kingdom made by an unprovoked invasion. What would you ask him about it?

Ask Frederick

• “How do you square invading Silesia with the Anti-Machiavel?”
• “What made Silesia worth a European war?”
• “What did leaving the field at Mollwitz teach you?”
• “Did you underestimate Maria Theresa?”
• “Was your dynastic claim to Silesia ever serious?”

Chapter 3 · Surviving the Seven Years' War

Prussia against most of Europe

1756 – 1763 · Saxony · Rossbach · Leuthen · Kunersdorf

In 1756 Frederick struck first again, invading Saxony to pre-empt an encircling coalition of Austria, France, Russia, Sweden and Saxony. Prussia, with around four million people, was now fighting powers with perhaps fifteen times that population.

He survived through mobility and the willingness to accept appalling casualties. In November 1757 at Rossbach he destroyed a much larger Franco-Imperial army in about ninety minutes. A month later at Leuthen he used the oblique order — concentrating overwhelming force on one enemy flank while screening the rest — to break an Austrian army nearly twice his size. Napoleon later called Leuthen a masterpiece.

The war also brought catastrophes. At Kunersdorf in 1759 he lost roughly half his army in a single day, and wrote that he believed all was lost. Berlin was occupied briefly by Russian and Austrian troops in 1760. By 1762 Prussian manpower was exhausted and the treasury was ruined.

His survival owed as much to luck as to genius. In January 1762 the Empress Elizabeth of Russia died; her successor Peter III, an admirer of Frederick, immediately switched sides and withdrew. Prussian historians called it the Miracle of the House of Brandenburg. The Treaty of Hubertusburg in 1763 restored the pre-war borders — Frederick kept Silesia, having gained nothing new at a cost of perhaps 180,000 Prussian soldiers and vast civilian suffering.

Why this matters

The Seven Years' War established Prussia as one of Europe's five great powers, and it demonstrated that Frederick's survival depended on an accident of dynastic timing as much as on his generalship.

You have seen a small state survive against most of Europe. What would you ask him?

Ask Frederick

• “How did the oblique order at Leuthen actually work?”
• “What did you think after losing half your army at Kunersdorf?”
• “How much did you owe to the death of the Empress Elizabeth?”
• “What did the war cost ordinary Prussians?”
• “Was starting the war by invading Saxony defensible?”

Chapter 4 · The First Servant of the State

Reform, toleration and its limits

1740 – 1786 · Potsdam · Sanssouci · Berlin

Frederick governed as an enlightened absolutist: reform imposed from above, without any transfer of power. He abolished judicial torture almost immediately on his accession, restricted the death penalty, and sponsored a codification of Prussian law that his successors completed. He rebuilt the Berlin Academy of Sciences and recruited scholars including Euler and Maupertuis.

His religious policy was genuinely unusual. He accepted Catholics, Jews, Huguenots and Mennonites as settlers on the principle that everyone should be allowed to reach heaven by their own route, valuing them as skilled subjects. His personal attitude to Judaism remained prejudiced, and Jewish subjects lived under restrictive regulations — the toleration was practical, not egalitarian.

After the wars he directed large-scale land reclamation, draining the Oderbruch marshes to create new farmland, settling colonists, and promoting the potato as insurance against grain failure. He abolished serfdom on royal estates but left it intact on the estates of the Junker nobility whose sons officered his army — the limit at which enlightenment stopped and the social bargain of the Prussian state began.

At Sanssouci, the small palace he built at Potsdam, he lived without his wife, wrote in French, played and composed for the flute, and kept his greyhounds. His relationship with Voltaire, who lived there from 1750, ended in mutual insult in 1753. Historians widely regard Frederick as homosexual, though the surviving evidence is indirect and the question remains debated.

“In my state, everyone can seek salvation in his own fashion.”

— Marginal note by Frederick II on a ministerial report, 1740 (wording varies in translation)

Why this matters

Frederick shows both the reach and the ceiling of enlightened absolutism: real legal and religious reform from the top, stopping precisely where it would have cost the nobility their privileges.

You have seen the reformer and his limits. What would you ask him about ruling?

Ask Frederick

• “Why did you abolish torture but keep serfdom on noble estates?”
• “What did you actually mean by religious toleration?”
• “Why did your friendship with Voltaire collapse?”
• “How did draining the Oderbruch change Prussia?”
• “Can a ruler be the servant of the state and also absolute?”

Chapter 5 · Old Fritz and What Was Done With Him

Partition, death, and a name later misused

1772 – 1786 and after · Potsdam · Poland

In 1772 Frederick was a principal architect of the First Partition of Poland, in which Prussia, Russia and Austria seized large territories from a neighbouring state that had not attacked any of them. Prussia took West Prussia, linking Brandenburg to East Prussia. It was a piece of coordinated great-power robbery, and Frederick's own writings about it are unsentimental.

In his last years he was a shabby, sardonic old man in a snuff-stained coat whom Prussians called Old Fritz, still rising before dawn to read reports, still inspecting fields and regiments. He died at Sanssouci on 17 August 1786, aged seventy-four. He had asked to be buried beside his dogs on the terrace there; his successor ignored the request, and the wish was finally honoured only in 1991.

His reputation then took on a life of its own. Nineteenth-century Prussian and German nationalist historians turned him into the founder of German greatness. The Nazi regime seized on that image, casting him as the model of a leader who held out against overwhelming odds — a use of history he could not have anticipated and which distorted him thoroughly.

Modern historians work to recover the actual record: a gifted commander who chose several of his wars, an administrator who genuinely improved law and agriculture, a writer of real ability, and a ruler who never let his professed principles limit Prussian advantage.

Why this matters

Frederick's afterlife is a warning about historical appropriation: later regimes selected the parts of him they wanted, and students need the documented ruler rather than the manufactured symbol.

You have reached the end, and the uses later made of him. What would you ask him?

Ask Frederick

• “How do you defend taking part in the partition of Poland?”
• “What would you say about later regimes using your name?”
• “Which do you think you did better — waging war or governing?”
• “Why did you want to be buried beside your dogs?”
• “Did the philosopher in you ever restrain the king?”

What Frederick changed

Frederick turned Prussia from a scattered middle-ranking territory into a European great power, and the army, bureaucracy and legal codification he built became the core of the state that unified Germany in 1871. His reign is the standard example of enlightened absolutism, and his campaigns were studied by every European staff college for a century and a half.

A debate that continues

Historians dispute whether Frederick's reforms make him a genuine child of the Enlightenment or whether his wars of choice and role in partitioning Poland make the label a piece of successful self-promotion.

Keep exploring — ask Frederick

• “What did the Seven Years' War teach you that Silesia had not?”
• “How much did music and writing matter to you alongside governing?”
• “Would you make the same decision about Silesia again?”
