Frederick II of Prussia was the 'enlightened despot' par excellence—a philosopher-king who corresponded with Voltaire, composed flute concertos, and transformed Prussia into a major European power through military genius and administrative efficiency. His brutal father's abuse only strengthened Frederick's cultivation and intellect.
Frederick's seizure of Silesia from Austria (1740) demonstrated his Realpolitik—he attacked without provocation because opportunity presented itself. The Seven Years' War (1756-1763) nearly destroyed Prussia, but Frederick's military brilliance preserved his kingdom against a coalition of Austria, Russia, and France.
At home, Frederick practiced 'enlightened absolutism'—religious tolerance, legal reform, agricultural improvement, and intellectual patronage combined with absolute royal power. He corresponded with philosophes, wrote Anti-Machiavel (then acted Machiavellian), and called himself 'first servant of the state.' Frederick established the Prussian tradition of military efficiency and bureaucratic excellence that shaped German history through Bismarck and beyond.
