Biography

Frederick William II ascended to the Prussian throne in 1786, inheriting a formidable state built by his austere uncle, Frederick the Great. In stark contrast to his predecessor, he was a patron of the arts and a man of considerable appetites, presiding over a court known for its splendor and his own complicated private life. His reign saw the construction of Berlin's iconic Brandenburg Gate and a golden age for music, with composers like Mozart and Beethoven receiving his support. Yet, politically, his rule was less assured. He pursued costly and ultimately inconclusive wars, intervened against the French Revolution with little success, and allowed the state's finances to decay through mismanagement and his own extravagance. By the time of his death in 1797, Prussia, while culturally enriched, was diplomatically isolated and burdened with debt, setting the stage for future crises.
