This chapter traces the development of Woolf’s late feminist politics and aesthetic experimentalism, focusing on her penultimate and final novels, The Years (1937) and Between the Acts (1941), and her anti-war pamphlet, Three Guineas (1938). It reads across these texts and Woolf’s wider writings from 1933–1941, including essays, unpublished drafts, and her fictional biography Flush (1933), to identify key strands of social and political enquiry in Woolf’s late works. The chapter pays particular attention to Woolf’s late analysis of the role of art in society and her evolving feminist-pacifist critique of the links between patriarchy, nationalism, fascism, and war. Rejecting a narrative of creative decline, the chapter highlights the productive relationship between political engagement and formal experiment in Woolf’s late works.
