Ideological Entrepreneurs, Multiplex Network Diffusion, and the Spread of Radical Innovations: Martin Luther’s Role in the Early Reformation

INFORMATION

Jared Rubin, together with his team, analyzes Martin Luther’s role in spreading the early Reformation, one of the most important episodes of radical institutional change in the last millennium. They argue that social relations played a key role in its diffusion because the spread of heterodox ideologies and their eventual institutionalization relied not only on private “infection” through exposure to innovation, but also active conversion to and the promotion of that new faith through personal ties. They conceive of that process as leader-to-follower directional influence originating with Luther and flowing to local elites through personal ties. Based on novel data on Luther’s correspondence, Luther’s visits, and student enrollments in Luther’s city of Wittenberg, his research team reconstructs Luther’s influence network to test whether local connections to him increased the odds of adopting Protestantism. Using regression analyses and simulations based on empirical network data, his team finds that the combination of personal/relational diffusion via Luther’s multiplex ties and spatial/structural diffusion via trade routes fostered adoption of the Reformation by cities, making possible Protestantism’s early breakthrough from a regional movement to a general rebellion against the Roman Catholic Church.
