A radical group in England that arose out of the civil war and English revolution, led by Gerrard Winstanley. The diggers preached and practiced a form of agrarian communism on common and waste ground (hence their name, they dug up the ground to plant crops). The first Digger community was established in April 1649 in Surrey and nine other communities quickly followed around southern and central England. Often cited as an early attempt at communism (in the sense of common ownership of property), the movement was supressed and its communities dispersed by local landowners.

The Diggers movement is immortalised in the song "The World Turned Upside Down"
