James Allen Vann III (20 November 1939 – 4 May 1986) was an American historian, specializing in German history of the early modern period.
He served on the faculty of the École des Hautes Études en Sciences Sociales in Paris from 1983–84.
[1] His 1975 work, The Swabian Kreis: Institutional Growth in the Holy Roman Empire, 1648–1715, established Vann among a group of young scholars whose new vision of the historical Holy Roman Empire challenged classical notions of that institution's viability and functionality.
In his study of Württemberg, he rejected traditional ideas of state building as a conscious social determinism, but instead explained the evolution of a German state in terms of relations between and among the dukes and the courtiers, privy councilors and the general representative body of the Landtag.
[1] Since 1985, the James Allen Vann Seminar, continued in his honor, offers an informal venue for scholars, graduate students, and other interested parties from the Atlanta area to discuss scholarly papers on topics concerning pre-modern European history and the relations between early modern Europe and the rest of the world.
