The Berlin Biennale (full name: Berlin Biennale für zeitgenössische Kunst, Berlin Biennale for Contemporary Art) is a contemporary art exhibition, which has been held at various locations in Berlin, Germany, every two to three years since 1998. The curator or curators choose the artists who will participate. After the event became established, annual themes were introduced. The Biennale is now underwritten by the German government through the Kulturstiftung des Bundes (Federal Culture Foundation), and is the second most important contemporary arts event in the country, after documenta. The Berlin Biennale was co-founded on March 26, 1996, by Klaus Biesenbach and a group of collectors as well as patrons of art. Biesenbach is also the founding director of KW Institute for Contemporary Art and currently serves as Director of MoMA PS1 and Chief Curator at Large at MoMA.
The first exhibition ran from 30 September to 30 December 1998 and was curated by Klaus Biesenbach, Hans-Ulrich Obrist and Nancy Spector. It took place in the Kunst-Werke Institute for Contemporary Art in Berlin-Mitte, at the Akademie der Künste in Pariser Platz and at the postal centre in Oranienburger Straße. More than 70 artists took part, including several unknowns who would later become famous, such as Franz Ackermann, Jonathan Meese, Thomas Demand and Olafur Eliasson. The show was interdisciplinary to reflect the context of contemporary art. During the opening week, the Thai artist Rirkrit Tiravanija catered a banquet for 1,000 guests in the post office gymnasium, and a three-night combination symposium and festival, Congress 3000, took place in the House of World Cultures.
