Voina (Russian: Война = War) is a Russian performance group known for their provocative and politically charged works of performance art. Voina was founded in 2007 by philosophy students at Lomonosov Moscow State University Oleg Vorotnikov and Natalia Sokol, In late February 2011 the activists Oleg Vorotnikov and Leonid Nikolayev were released on bail after four months in Moscow police custody, in connection with an anti-corruption protest. They face up to seven years of prison. In response to the detention, graffiti artist Banksy decided to raise money for the artists. They have also been denounced by right-wing groups like the People’s Synod.
