State Britain is an installation artwork by Mark Wallinger displayed in Tate Britain in January 2007. It is a recreation from scratch of a protest display about the treatment of Iraq, set up by Brian Haw outside Parliament and eventually confiscated by the police. Haw's display contained several hundred items donated by members of the public. As well as continuing the protest, Wallinger's recreation in a different context also brings up questions of authenticity. Wallinger received a Turner Prize nomination in 2007 for this piece.
