Frederick II, known as Frederick the Great, was King of Prussia from 1740 to 1786. An enlightened ruler and a leading military strategist, he turned Prussia into a major European power while corresponding with Enlightenment philosophers, including Voltaire.

Frequently asked questions

To understand this title, picture a king who, over 46 years on the throne, transformed a small kingdom into a great European power. Frederick II (1712-1786) is nicknamed "the Great" not for his stature but for his military successes and his political vision. The key thing to remember is that he embodies the model of the enlightened despot: he rules alone yet calls himself the "first servant of the State," modernizes the justice system, tolerates all religions, and corresponds with Voltaire. His conquest of Silesia in 1742 and his victories during the Seven Years' War (Rossbach, Leuthen) make him a legendary strategist.

Anecdotes

As a teenager, Frederick struggled to cope with the military discipline imposed by his father, the “sergeant king” Frederick William I. In 1730, at the age of 18, he tried to flee to England with his friend Hans Hermann von Katte. Caught, the two young men were arrested: the king forced Frederick to witness his friend's execution, an ordeal that scarred him for life.

Frederick II was passionate about music and played the transverse flute remarkably well. He composed many sonatas and concertos himself, and organized concerts every evening at his palace of Sanssouci. In 1747, he received the composer Johann Sebastian Bach, to whom he proposed a complex musical theme that gave rise to *The Musical Offering*.

The king maintained a long correspondence with Voltaire, whom he admired and invited to his court at Potsdam from 1750 onward. But the two strong personalities eventually fell out in 1753, after quarrels over money and pride. Despite the break, they resumed their written correspondence until the end of their lives.

Frederick II adored dogs, especially his Italian greyhounds, whose company he often preferred to that of humans. He explicitly asked to be buried beside them on his estate of Sanssouci, simply and without pomp. This wish was not granted until 1991, more than two centuries after his death.

Nicknamed “the philosopher king,” Frederick II worked tirelessly and slept little, often rising before dawn. He called himself “the first servant of the State” and believed that the sovereign should devote himself entirely to the common good, the ideal of enlightened despotism.
