This book is the most recent contribution to the somewhat arcane subfield of “Monnet Studies.” Research for it was undertaken in the mid-1990s, at about the time when the two big biographies of “l'Inspirateur” by Francois Duchene and Eric Roussel appeared, but apparently competed before the publication of the next landmark in the literature, the anthology edited by G. Bossuat and A. Wilkens (Jean Monnet, l'Europe, et les chemins de la paix. Paris: Publications de la Sorbonne, 1998). Since in a number of important cases the individual articles written for the latter delve much deeper into the topics that Fransen covers in this short book, The Supranational Politics of Jean Monnet is unfortunately already rather dated.
