I examine the effect of the Green Revolution on religious riots in India between 1957 and 1985. Using an instrumental variable framework on a district level panel dataset, I find that riots are longer after the Green Revolution is introduced, with a 1% increase in the duration of a riot. Employing alternative measures of riot intensity and incidence, I find suggestive evidence of an overall increase in religious conflict after the introduction of mechanization via the Green Revolution. I show that the Green Revolution reduces the opportunity cost of engaging in conflict by reducing the demand for labor in agriculture due to mechanization. There is suggestive evidence to show that religious violence is exacerbated in an election year. Additional results indicate the mitigation of the effects of the Green Revolution on conflict in a good rainfall year and an increase in the intensity of conflict in districts in north India. My findings shed light on the unintended consequences of technology in agriculture as well as the mechanisms through which this technology influences ethnic conflict.
