Abstract
Mabel Holland Thomas (1861-1929), later Grave, is a quintessential example of an anarchist woman with an eclectic body of work, whose manifold contribution has been largely overlooked or considered through the prism of her romantic association with a leading figure of the French and international anarchist movement, Jean Grave (1857-1939). This article offers an analytical biographical account emphasizing her privileged and artistic family background and Welshness, exploring how they connected with her later embrace of anarchism through the themes of nature and the landscape, social justice, education, and feminism.
