The Sorrows of Young Werther was Goethe's first major success, turning him from an unknown into a celebrated author practically overnight. Napoleon Bonaparte considered it one of the great works of European literature. He thought so highly of it that he wrote a soliloquy in Goethe's style in his youth and carried Werther with him on his campaigning to Egypt. It also started the phenomenon known as the "Werther-Fieber" ("Werther Fever") which caused young men throughout Europe to dress in the clothing style described for Werther in the novel.
Werther made Goethe one of the first international literary celebrities. Towards the end of his life, a personal visit to Weimar became crucial to any young man's tour of Europe. Werther was an important novel of the Sturm und Drang period in German literature, and influenced the later Romantic literary movement.
