Periodization and Historiography: Studying American Political Development in the Progressive Era, 1890s–1916

In keeping with the social character of the advancement of knowledge, and in spite of a strong competitive impulse among scholars to magnify small differences into warring schools of thought, the leading historical writings in the past four decades have yielded substantial agreement on the identification of critical trends that were transforming United States society in the period of the 1890s to 1916. Implicitly, at least, they may well have been anticipating the way to resolving some latest of these small differences before they get too far out of hand, such as that between “social history” and “political history” and, in a variation upon the theme, that between “society-centered” (or “movement-centered” or “interest-centered”) and “state-centered” history. The common acknowledgment of critical trends has served newcomers and veterans alike, including partisans on either side of these differences, and historians in the various genres, in the selection of authoritative frameworks of continuing research into the period. In this respect, the historical discipline shares with other disciplines, including those in the physical sciences, attributes held to be common to a “normal science.”
