Jonathan’s research is focused on modern British and Commonwealth history in its global context.

His current research project, which expands on the approaches and methodologies explored in Fighting the People’s War, is a new three volume study of the causes, conduct and consequences of the Second World War. This project sets out to develop a fresh account of the war that bridges the gap between traditional military histories and the mainstream political, social, cultural, economic and environmental histories of the period.

To pursue this aim, the trilogy will engage in a series of interlocking analytical approaches: it will fully embrace a global, or transnational, ‘vista’ of the Second World War; it will be integrative, not only in terms of military, global, social, economic, environmental and cultural history, but also with regards to marginalized histories; and it will be committed to exploring the ‘culture of war’, the experiential. This new history aims, therefore, to interrogate the personal alongside, and in the context of, the great complex events of the 1930s and 1940s. It will be a history of women and men of varied races, creeds and socio-economic backgrounds; one that links the home and battle fronts and places the dramatic political, economic, social, cultural and environmental changes of the second half of the Twentieth Century in a new context.

The trilogy will be published by Penguin Random House (Viking) in the UK, HarperCollins in the US, CITIC in China and Spectrum in the Netherlands.
