This paper investigates the extent to which rights-based education is utilised in textbooks from conflict-affected countries. Drawing on a unique dataset of 528 secondary social science textbooks from 71 countries from 1966 to 2008, we analyse factors that predict a rights discourse in texts. We find that textbooks from conflict-affected nations are significantly less likely to emphasise a rights-based discourse, while more recently published textbooks from more democratic countries are more likely to emphasise a rights discourse. Our findings have ramifications for curricular reform and rights-based education in conflict-affected nations.
