Sturm und Drang was a proto-Romantic movement in German literature and music that occurred between the late 1760s and early 1780s. Within the movement, individual subjectivity and, in particular, extremes of emotion were given free expression in reaction to the perceived constraints of rationalism imposed by the Enlightenment and associated aesthetic movements. The period is named after Friedrich Maximilian Klinger's play of the same name, which was first performed by Abel Seyler's famed theatrical company in 1777.
The philosopher Johann Georg Hamann is considered to be the ideologue of Sturm und Drang; other significant figures were Johann Anton Leisewitz, Jakob Michael Reinhold Lenz, H. L. Wagner, and Friedrich Maximilian Klinger. Johann Wolfgang von Goethe and Friedrich Schiller were notable proponents of the movement early in their lives, although they ended their period of association with it by initiating what would become Weimar Classicism.
