An early flowering of German literature is the Middle High German period of the High Middle Ages. Modern literature in German begins with the authors of the Enlightenment (such as Herder) and reaches its "classical" form at the turn of the 18th century with Weimar Classicism (Goethe and Schiller).

Medieval German literature refers to literature written in Germany, stretching from the Carolingian dynasty; various dates have been given for the end of the German literary Middle Ages, the Reformation (1517) being the last possible cut-off point.
The Old High German period is reckoned to run until about the mid-11th century, though the boundary to Early Middle High German (second half of the 11th century) is not clear-cut.
The most famous work in OHG is the Hildebrandslied, a short piece of Germanic alliterative heroic verse which besides the Muspilli is the sole survivor of what must have been a vast oral tradition. Another important work, in the northern dialect of Old Saxon, is a life of Christ in the style of a heroic epic known as the Heliand.
Middle High German proper runs from the beginning of the 12th century. In the second half of the 12th century, there was a sudden intensification of activity, leading to a 60-year "golden age" of medieval German literature referred to as the mittelhochdeutsche Blütezeit (1170-1230). This was the period of the blossoming of MHG lyric poetry, particularly Minnesang (the German variety of the originally French tradition of courtly love). One of the most important of these poets was Walther von der Vogelweide. The same sixty years saw the composition of the most important courtly romances. These are written in rhyming couplets, and again draw on French models such as Chrétien de Troyes, many of them relating Arthurian material, for example, Parzival by Wolfram von Eschenbach. The third literary movement of these years was a new revamping of the heroic tradition, in which the ancient Germanic oral tradition can still be discerned, but tamed and Christianized and adapted for the court. These high medieval heroic epics are written in rhymed strophes, not the alliterative verse of Germanic prehistory. For example, the Niebelungenlied.
The Baroque period (1600 to 1720) was one of the most fertile times in German literature. Many writers reflected the horrible experiences of the Thirty Years' War, in poetry and prose. Grimmelshausen's adventures of the young and naïve Simplicissimus, in the eponymous book Simplicius Simplicissimus, became the most famous novel of the Baroque period. Andreas Gryphius and Daniel Caspar von Lohenstein wrote German language tragedies, or Trauerspiele, often on Classical themes and frequently quite violent. Erotic, religious and occasional poetry appeared in both German and Latin.
Sturm und Drang (the conventional translation is "Storm and Stress"; a more literal translation, however, might be storm and urge, storm and longing, or storm and impulse) is the name of a movement in German literature and music taking place from the late 1760s through the early 1780s in which individual subjectivity and, in particular, extremes of emotion were given free expression in response to the confines of rationalism imposed by the Enlightenment and associated aesthetic movements. The philosopher Johann Georg Hamann is considered to be the ideologue of Sturm und Drang, and Johann Wolfgang von Goethe was a notable proponent of the movement, though he and Friedrich Schiller ended their period of association with it, initiating what would become Weimar Classicism.
Young Germany (Junges Deutschland) was a loose group of Vormärz writers which existed from about 1830 to 1850. It was essentially a youth movement (similar to those that had swept France, Ireland and originated in Italy). Its main proponents were Karl Gutzkow, Heinrich Laube, Theodor Mundt and Ludolf Wienbarg; Heinrich Heine, Ludwig Börne and Georg Büchner were also considered part of the movement. The wider circle included Willibald Alexis, Adolf Glassbrenner and Gustav Kühne.
Under the Nazi regime, some authors went into exile (Exilliteratur) and others submitted to censorship ("internal emigration", Innere Emigration)
The Nobel Prize in Literature has been awarded to German language authors twelve times (as of 2007), or the third most often after English and French language authors (with 27 and 13 laureates, respectively).
