The Clandestine Insurgent Rebel Clown Army (also known as CIRCA and Clown Army) is a anti-authoritarian left-wing activist group that uses clowning and non-violent tactics to act against corporate globalisation, war, and other issues.
The group originated circa 2003 in the United Kingdom. CIRCA emerged from the direct action movement and has participated in protests against George W. Bush's visit to the UK in 2003 and demonstrations against the 2003 invasion of Iraq.
The group was particularly prominent in many of the actions organised around the 31st G8 summit held in Gleneagles during July 2005.
Members of CIRCA entertained children in Auchterarder while waiting for permission to march near the summit.
CIRCA has active groups in the United Kingdom, Ireland, the Netherlands, Belgium, France, Denmark, Germany, and Israel, and many other groups have appeared that have been inspired by the work of the original group.
Kriya Arts was part of the original group of fifteen people who gathered in a cottage in the Cotswolds, headed up by art activist Jon Jordon, in 2003. There they helped each other put together a training programme for the Rebel Clow Army's 'soldiers'.
