William Brustein’s The Social Origins of Political Regionalism: France 1849–1981 tackles a central puzzle in modern French history: why regions with similar agrarian economies—like Argentré-du-Plessis in Brittany and Bonnieux in Provence—have persistently voted in opposite ideological blocs for more than a century. Brustein notes that while western France has consistently aligned with the Right, Mediterranean France has been just as reliably Left, a striking divergence visible in national legislative elections from 1849 through 1981. He situates this pattern within the broader phenomenon of political regionalism, whereby entire areas maintain distinctive political loyalties across generations, as seen in the American South, Canadian Saskatchewan, or Indian Kerala. Existing explanations, Brustein argues, falter because they fail to bridge history’s concern with local particularities and sociology’s search for generalizable models. His solution is a theoretical framework that fuses rational-choice assumptions about individual behavior with the Marxist concept of the mode of production. According to Brustein, discrete regional modes of production shaped distinct social structures in France, which in turn generated enduring constellations of cultivators’ interests and predictable patterns of political behavior. To test this mode-of-production theory, he turns to archival data from three pivotal legislative contests: 1849, when the divisions of Left and Right were first clearly marked; 1914, on the eve of World War I; and 1981, when François Mitterrand’s Socialist victory brought the Left to power. France provides an ideal case, he contends, not only because of its long-standing and sharply polarized regional voting blocs but also because both western and Mediterranean regions were largely agrarian and politically peripheral, making economic structural differences more salient. By combining comparative theory with close empirical analysis, Brustein demonstrates that regi
