Disappointed with Versailles, Voltaire goes to the court of the King of Prussia in 1750. Soon it becomes clear that he and Frederick are incompatible in temperament and lifestyle. A rift occurs. Voltaire is in danger and sets off on a journey. The Prussian officials in the Free Imperial City of Frankfurt detain him on Frederick's orders: his luggage is confiscated, he is placed under house arrest, and he experiences humiliation and arbitrariness. Frederick and Voltaire never see each other again. "The Philosopher at Court" - Hans Joachim Schädlich not only highlights the incompatibility of a free spirit and absolutist power but also brings into focus Voltaire's famous companion Émilie du Châtelet and a great enlightened love.
