conventionally translated as "Storm and Stress") is a proto-Romantic movement in German literature and music that took place from the late 1760s to the early 1780s, in which 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 for Friedrich Maximilian Klinger's play Sturm und Drang, which was first performed in 1777. The philosopher Johann Georg Hamann is considered to be the ideologue of Sturm und Drang, with Jakob Michael Reinhold Lenz, H. L. Wagner and Friedrich Maximilian Klinger also significant figures. Johann Wolfgang von Goethe was also a notable proponent of the movement, though he and Friedrich Schiller ended their period of association with it by initiating what would become Weimar Classicism. Jena Romanticism Jena Romanticism – also the Jena Romantics or Early Romanticism (Frühromantik) – is the first phase of Romanticism in German literature represented by the work of a group centered in Jena from about 1798 to 1804, notably Friedrich Schlegel, August Wilhelm Schlegel, Novalis, Ludwig Tieck, and Friedrich Wilhelm Joseph Schelling. These thinkers were primarily concerned with the problems posed by Immanuel Kant in the Critique of Judgment and what was seen as the failure of the Analytic of the Sublime to accomplish the task set before it: bridging the gap between pure and practical reason. In a different vein, Friedrich Hölderlin and Heinrich von Kleist also grappled with similar philosophical issues in a manner different from the Jena circle. Heidelberg Romanticism Heidelberg was the centre of the epoch of Romantik (Romanticism) in Germany. The phase after Jena Romanticism is often called Heidelberg Romanticism (see also Berlin Romanticism). There was a famous circle of poets, the Heidelberg Romantics, such as Joseph von Eichendorff, Johann Joseph von Görres, Ludwig Achim von Arnim, and Clemens Brentano. A relic of Romanticism is the Philosophers' Walk (), a scenic walking path on the nearby Heiligenberg, overlooking Heidelberg. The Romantik epoch of German philosophy and literature, was described as a movement against classical and realistic theories of literature, a contrast to the rationality of the Age of Enlightenment. It elevated medievalism and elements of art and narrative perceived to be from the medieval period. It also emphasized folk art, nature and an epistemology based on nature, which included human activity conditioned by nature in the form of language, custom
