Muslim conquest and institutional formation

Recent studies suggest that Muslim military conquest (632–1100 CE) generated an institutional equilibrium with deleterious long-run political economy effects. This equilibrium was predicated on mamluk institutions: the use of elite slave soldiers (mamluks) and non-hereditary property rights over agricultural lands to compensate them (iqta). This paper evaluates this historical narrative by exploring the accuracy of its initial step. Using a difference-in-differences strategy, I show that conquest changed institutions in conquered territories. I then provide suggestive evidence that the presence and efficacy of mamluk institutions affected this institutional configuration and that leaders survived longer in power during the conquest period.
