Michael Kohlhaas is a novella by the German author Heinrich von Kleist, based on a 16th-century story of Hans Kohlhase. Kleist published fragments of the work in volume 6 of his literary journal Phöbus in June 1808. The complete work was published in the first volume of Kleist's Erzählungen (novellas) in 1810.
Both the theme (a fanatical quest for justice) and the style (existentialist detachment posing as a chronicle) are surprisingly modern. They resonated with other authors more than a century after they were written.
