“Tommaso Milani’s study of the Belgian Social Democrat Hendrik de Man is a welcome contribution to the history of European social democracy in the twentieth century. … Milani’s study of de Man is an insightful, carefully argued work that will be useful to scholars and graduate students and is accessible to advanced undergraduates.” (William Smaldone, H-Net Reviews, h-net.org, July, 2022)“Combining a precise and eloquent writing style with an impressive command of languages … Milani first retraces the theoretical roots of de Man’s socialism. … A valuable and convincing contribution to the political historiography of the 1930s.” (Jens van de Maele, Journal of Belgian History, Issue (1-2), 2021)
