Frederick the Great

1712–1786 · Prussian (Berlin/Potsdam) · Enlightenment Era, 18th Century Europe

Known for: Transformed Prussia into a major European power—military genius, Enlightenment patron, and flute-playing philosopher-king

Frederick II of Prussia transformed a minor German kingdom into a European great power through military brilliance and aggressive expansion. He survived the Seven Years' War (1756–1763) against a coalition of France, Austria, and Russia—often considered his greatest achievement, as Prussia was outnumbered 10 to 1.

He was also an Enlightenment intellectual who corresponded with Voltaire (they later quarreled bitterly), composed flute sonatas, wrote philosophical treatises, and abolished torture. He modernized Prussian law, promoted religious tolerance, and attracted immigrants through progressive policies.

His father Frederick William I had tried to beat the arts out of him—Frederick ran away with his friend Hans Hermann von Katte, was caught, and was forced to watch Katte's execution from a prison window. This trauma shaped his entire personality.
