In this dissertation i argue that the internet has a positive impact on the likelihood of ethnic riots. To make this argument I put forward three major claims. First, ethnic riots are best understood as performances that aim to clarify ambiguities in the social order. Second, communication technologies structurally constrain the flow of information passing through them. Third, the internet is unique among modern Information Communication Technologies in its capacity for inducing ethnic riots. I provide two types of empirical evidence to support these claims: a cross-national analysis of internet penetration and a case study of India. The former provides evidence for the central claim, finding that the internet has a positive effect on the likelihood of ethnic conflict after a threshold of internet penetration is met. The latter sketches the limits of the proposed theory, finding that internet penetration decreased the likelihood of ethnic riots in India. I argue this is a result of welfare contextualization of the internet.
