Eley's early work focused on the radical nationalism in Imperial Germany and fascism, but has since grown to include theoretical and methodological reflections on historiography and the history of the political left in Europe.

Eley is particularly well known for his early study, The Peculiarities of German History (first published in German as Mythen deutscher Geschichtsschreibung in 1984), co-authored with David Blackbourn (a fellow Briton, who now teaches at Vanderbilt University), which challenged the orthodoxy in German social history known as the Sonderweg thesis. His most successful book is Forging Democracy: The History of the Left in Europe, 1850-2000, which has been translated into Spanish, Portuguese, Serbian, Korean, Turkish and Greek. Recently, he published a collection of essays on fascism called Nazism as Fascism: Violence, Ideology, and the Ground of Consent in Germany, 1930-1945 with Routledge Press.
