Illiberalism pushes back against liberalism after having experienced it, and this "post-'' aspect is critical because it explains the disillusion.
The two genealogies differ on their relationship to liberalism. The New Right calls for a fundamental break with it and refers to the mythical thousand-year-old European identity. Classical conservatism, on the other hand, shares with liberalism a focus on the Enlightenment, modernization, and emancipation but takes a critical view thereof. The two also position themselves differently with regards to the fascist currents of the interwar years: the New Right more openly rehabilitates these than classical conservatism.
