Berlin and Sans-Souci

In Short

Set during the early, peaceful years of Frederick the Great's reign, this historical romance follows the Prussian court as it transitions from the battlefields of Silesia to the gilded halls of Berlin and Potsdam. Frederick strives to build an enlightened state centered on philosophy and religious tolerance, but his ambitions are continuously derailed by the unruly hearts of those around him. The narrative weaves together three distinct threads of intrigue: the forbidden, tragic romance between the brave Officer Frederick von Trenck and the King’s spirited sister, Princess Amelia; the dramatic private life of the celebrated Italian dancer Signora Barbarina, who becomes an unwitting pawn among high-ranking nobles; and the volatile, razor-thin friendship between the King and the brilliant yet petty French philosopher Voltaire at Sans-Souci.

The Story

Frederick II of Prussia begins his reign eager to transform his kingdom into a beacon of reason, art, and justice. Standing in his palace, he envisions a grand universal house of worship—a Pantheon—where all religious sects might gather under the light of pure intellect. Yet his closest confidants warn him that human nature is far too fragile and stubborn for such sweeping ideals. Frederick quickly learns that governing a nation's military strength is far simpler than controlling the private desires of his subjects and kin.

The court’s delicate balance shatters under the weight of secret passions. The King’s younger sister, Princess Amelia, falls deeply in love with a handsome, ambitious young officer of the royal guard, Frederick von Trenck. Their secret romance flourishes in dark garden corners and disguised letters, even as older, wiser courtiers warn Trenck that loving a royal princess is tantamount to high treason. When rumors reach the King, Frederick confronts Trenck directly. Though the youth initially denies his secret meetings, his obstinate refusal to betray his honor drives a wedge between officer and sovereign. Suspicion festers, and when Trenck is later caught corresponding with relatives in Austrian service, Frederick strips him of his commission and imprisons him in a dark fortress.

Driven nearly to despair by her lover's sudden disappearance and subsequent capture, Princess Amelia’s once-radiant spirit turns bitter and hollow. A failed, bloodied escape attempt by Trenck leaves him locked in heavier chains, and Amelia abandons all hope of personal happiness. Sacrificing her youth, health, and beauty to relentless grief, she withdraws into a ghostly, physically shattered shadow of her former self, harboring a quiet, lifelong resentment toward her royal brother.

Concurrently, the arrival of Signora Barbarina, an exquisite Italian dancer, sends shockwaves through the Prussian high society. Captivated by her extraordinary grace, the King grants her his protection and patronage. Barbarina, proud and intensely protective of her artistic reputation, finds herself pursued by high-ranking suitors. Chief among them is young Cocceji, the son of the Prussian High Chancellor. When Cocceji’s haughty mother attempts to intimidate Barbarina into relinquishing her son, the dancer's fierce pride is incensed. Out of pure defiance against the arrogant aristocracy rather than true affection, Barbarina agrees to wed the young noble. The High Chancellor responds by securing royal warrants to arrest his own son, setting off a bitter legal and social war that ultimately fractures families and forces Barbarina to navigate a treacherous world of aristocratic vanity.

Meanwhile, at his beloved retreat of Sans-Souci, Frederick seeks intellectual solace in the company of the world's greatest thinkers, inviting the famous French philosopher Voltaire to reside at court. What begins as a sublime meeting of minds rapidly devolves into a nightmare of petty jealousies and financial bickering. Voltaire, obsessed with accumulating wealth and ousting rival writers like Maupertuis and D’Argens, turns the peaceful sanctuary into an arena of slanderous intrigue. Frederick, realizing that even the grandest genius can possess a small, miserly soul, grows weary of the poet's endless demands and hidden malice. After a series of heated disputes over pensions, court favors, and personal honor, Voltaire packs his bags and takes his final leave. Frederick returns his bow with cold, quiet dignity, leaving their once-celebrated friendship reduced to ashes as the King resolves to stand alone.

The People

• Frederick II (The King): A deeply complex monarch who strives to be an enlightened philosopher-king, ruling through intellect and justice. His desire for rational order is constantly thwarted by the irrational passions of his family and court, forcing him to adopt a stern, solitary authority that isolates him from those he loves.
• Princess Amelia: The King’s younger sister, initially a vibrant, childlike beauty known as the "April Fairy." Her intense, unyielding love for Frederick von Trenck leads to her utter devastation when he is imprisoned; she transforms into a sickly, hollow figure living only for quiet vengeance and memory.
• Frederick von Trenck: A brave, handsome, and fiercely proud young officer in the King's body-guard. His boundless romantic devotion to Princess Amelia blinds him to the immense political dangers surrounding him, resulting in his downfall, imprisonment, and ruin.
• Signora Barbarina: A world-renowned Italian dancer whose magnificent talent is equaled only by her fiery, unyielding self-respect. Refusing to be looked down upon by the Prussian aristocracy, she uses her wit and influence to fight the arrogant social order on her own terms.
• Voltaire: The brilliant French poet and philosopher whose matchless intellect is paired with a miserly, scheming, and deeply envious personality. He seeks absolute dominance over the King's affections, destroying his own position through ceaseless intrigue.
• Marquis d'Argens: A faithful, warm-hearted French noble at Frederick's court who offers genuine loyalty and affection, serving as a peaceful counterweight to Voltaire's volatile toxicity.

In Its Own Voice

"The only proof by which we can know that we can sincerely love God, lies in a steadfast and strong purpose to obey Him. According to this, we need no other religion than our reason..."

— The King outlines his lofty vision of an enlightened, universal faith to his skeptical advisor Jordan.

"Woe to him who calls us so! we will slay him, and walk over his dead body. And now for some desperate resolve."

— Frederick von Trenck speaks to his fellow fugitive as they attempt a perilous escape from royal captivity.

"Be as good a man as you are a great poet. That is the most beautiful offering you can bring me."

— Frederick gently admonishes Voltaire, attempting to appeal to the famous writer's higher nature amid court squabbles.

What It's Really About

Beneath its intricate web of court intrigue, romantic rendezvous, and royal pageantry, the novel explores the tragic, irreconcilable conflict between absolute political power and human feeling. Frederick the Great desires to build a society governed by cold, luminous reason, yet he is surrounded by individuals whose lives are driven entirely by unyielding emotion—whether it is Trenck’s obsessive romance, Amelia’s devastating grief, Barbarina’s fierce personal pride, or Voltaire’s insatiable avarice.

The narrative questions whether an absolute ruler can ever truly maintain genuine friendships or family bonds without reducing those around him to mere instruments of statecraft. Every major character who attempts to assert personal autonomy against the King's grand design is ultimately crushed, exiled, or hardened by the weight of the crown. In the end, the book presents a poignant meditation on the loneliness of power, suggesting that the pursuit of total order requires the systematic sacrifice of warm human affection.

Why Read It Today

Readers who enjoy dramatic, sweeping historical fiction filled with high-stakes romance and political maneuvering will find much to admire in this mid-nineteenth-century work. It offers a fascinating, intimate look into the Prussian court, bringing historical figures to life not as dry textbook entries, but as passionate, flawed, and deeply human individuals. The psychological duel between Frederick and Voltaire alone provides brilliant intellectual entertainment, while the tragic romance of Trenck and Amelia carries an enduring emotional force.

The reading experience is lush and atmospheric, rich with descriptions of eighteenth-century palace life, secret garden meetings, and vibrant theatrical performances.
