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.[1][2] The Berlin Biennale was co-founded on 26 March 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.[3]
