Academics have grown increasingly interested in non-state actors’ attempts at governance. In Inside Rebellion, Jeremy Weinstein finds that a violent non-state actor’s discipline is central to determining whether it will build governance structures and protect populations from violence or kill indiscriminately. Weinstein concludes that richer organizations have a harder time maintaining discipline because they attract opportunists obsessed with immediate gain, and thus predisposed to violence, while resource-poor organizations instead attract committed individuals with a shared sense of purpose. Thus, Weinstein believes resource-poor organizations are more likely to establish governance and provide services. In Rebel Rulers, Zachariah Cherian Mampilly examines the variance in governing strategies among insurgent groups, focusing on the groups’ initial leadership decisions and subsequent interactions with various actors. Among other things, he argues insurgent groups are more likely to establish governance if the state had significant penetration prior to insurgent takeover of a region.
