In the context of calls to decolonise education in European contexts, this paper draws on coloniality-based critiques of Eurocentric modernity to take up the links between democracy, slavery, and colonialism in education. Starting from the position that modernity requires epistemological support to sustain racism and white supremacy in European democracies, we read coloniality-based critiques of democracy with empirical literature about the teaching of slavery. We consider possibilities for revised critical engagements with democracy and with the history of European colonialism and (...) slavery. The paper builds on and contributes to recent decolonial critiques of democracy in education by explicitly engaging a tension raised around the possibility of disentangling democracy from its colonial roots.
