The onset of intrastate conflict depends on two main factors: rebel incentives and state capacity to deter them. This paper develops a rationalist argument suggesting that modernization, through economic growth benefiting both individuals and states, could influence civil conflict likelihood in multiple ways.
Using World Bank data, we created a modernization index and applied strategic models. The findings reveal an interesting arc: while early stages of modernization might paradoxically increase the risk of conflict as new opportunities emerge alongside incomplete state capacity gains, long-term development generally stabilizes societies.
