Piketty's "Capital in the Twenty-First Century" has brought the issue of inequality to the centre of political debate. This article explores contemporary research on the relationship between education and inequality in conflict-affected contexts with a view to seeing how Piketty's work speaks to these issues as a field of research and practice. The article provides a critique of Piketty's approach, arguing for a broader, interdisciplinary and holistic approach to exploring and addressing inequality in education in conflict-affected contexts in their multiple economic, cultural and political dimensions. In doing so the article also lays out an analytical framework inspired by cultural political economy for researching education systems in conflict contexts which seeks to go beyond narrow human capital framings of education and address the multiple potential of education to promote sustainable peace and development in and through education.
