Political science has long viewed education as an instrumental factor in developing support for democracy and beneficial for democratization. However, governments, both democratic and authoritarian, have substantial control over the curriculum and develop education institutions with the specific aim to instill in students the norms and values that underpin the regime. With this in mind, this study asks, does the effect of education vary by the political regime in which education was undertaken? We use a quasi-experimental approach exploiting European compulsory schooling reforms, implemented under both democratic and authoritarian regimes, to answer this question. We find that education has no effect on principle and functional support for democracy, but that education’s effect on satisfaction with democracy is conditional on regime type. For those educated under a democratic regime, education led to greater satisfaction with democracy, whereas those educated under an authoritarian regime became less satisfied with democracy.
