The French historian Marc Bloch has often been praised for his interdisciplinary approach. This book demonstrates the importance of both Vidalian geography and Durkheimian sociology for Bloch and the significant, but often overlooked, differences between his approach and theirs. In contrast to much other work on Bloch, Professor Friedman highlights the intellectual and institutional contexts of Bloch's works, arguing that only by a careful examination of the debates in which he was involved can one begin to come to terms with the nature of his contribution.
