 The so-called "Historikerstreit" ("Historians' Quarrel") was not at all one-sided, because Habermas was himself attacked by scholars like Joachim Fest, Hagen Schulze, Horst Möller, Imanuel Geiss and Klaus Hildebrand.In turn, Habermas was supported by historians such as Martin Broszat, Eberhard Jäckel, Hans Mommsen, and Hans-Ulrich Wehler.Habermas and Jacques Derrida engaged in a series of disputes beginning in the 1980s and culminating in a mutual understanding and friendship in the late 1990s that lasted until Derrida's death in 2004.
