The Mansfeld Regiment’s social organization and material contexts shaped the way it was formed, the path it took from Dresden to Lombardy, and the way it disintegrated. The concepts of the military revolution and the fiscal-military state are still relevant. But developing fiscal-military infrastructure was weak, which laid the groundwork for the Mansfeld Regiment’s loss of funding and failure. In this regiment’s daily operations I did not see the changes in social discipline that were supposedly intertwined with the military revolution. What I have found about the Mansfeld Regiment and the Saxon army may serve as a basis for re-examining some historical assumptions about early seventeenth-century armies. Daily interactions within this pathetic regiment are also an important source for the historical social anthropology of early-modern Europe, shedding light on masculinity, violence, identity formation, and marginalization.
