Throughout the 1920s Mexico was rocked by attempted coups, assassinations, and popular revolts. Yet by the mid-1930s, the country boasted one of the most stable and durable political systems in Latin America. In the first book on party formation conducted at the regional level after the Mexican Revolution, Sarah Osten examines processes of political and social change that eventually gave rise to the Institutional Revolutionary Party (PRI), which dominated Mexico's politics for the rest of the twentieth century. In analyzing the history of socialist parties in the southeastern states of Campeche, Chiapas, Tabasco, and Yucatán, Osten demonstrates that these 'laboratories of revolution' constituted a highly influential testing ground for new political traditions and institutional structures.  The Mexican Revolution's Wake: The Making of a Political System, 1920–1929 (Cambridge UP, 2018) shows how the southeastern socialists provided a blueprint for a new kind of party that struck calculated balances between the objectives of elite and popular forces, and between centralized authority and local autonomy.
