Caryl Churchill's 1976 play Light Shining in Buckinghamshire is set during the English Civil War in the 1640s. It focuses on a group of radical thinkers and activists from that time, including Levellers who advocated for political reform, equality before the law, and universal male suffrage, as well as Diggers who were agrarian communists and Ranters who rejected religious scripture. The play depicts their ideological debates and the tensions between their aspirations for political and social change and the realities of the authoritarian world of their time.
