Today is the 100th anniversary of the death of the Russian anarchist and scientist Pyotr Kropotkin.
Kropotkin was a proponent of a decentralised society free from government and based on voluntary associations of self-governing communities and worker-run enterprises. Among other books and articles he wrote the important Mutual Aid: A Factor of Evolution.
After spending most of his life in exile, he returned to Russia after the Revolution but was disillusioned by the Bolsheviks. He died of pneumonia aged 78.
