Anthony D. Smith describes how intellectuals played a primary role in generating cultural perceptions of nationalism: Smith posits the challenges posed to traditional religion and society in the
Age of Revolution propelled many intellectuals to "discover alternative principles and concepts, and a new mythology and symbolism, to legitimate and ground human thought and action". The simultaneous concept of 'historicism' was characterised by an emerging belief in the birth, growth, and decay of specific peoples and cultures, which became "increasingly attractive as a framework for inquiry into the past and present and [...] an explanatory principle in elucidating the meaning of events, past and present".
Johann Gottfried Herder and
Johann Gottlieb Fichte are considered key figures who argued for such a cultural definition of
nationhood. They emphasised the distinctness of national cultures based predominantly around language, stressing its character as "the epitome of people’s unique historical memories and traditions and the central source of the national spirit".
Miroslav Hroch argues cultural nationalism laid the foundation for the emergence political nationalism. For
Yael Tamir, the right to national self-determination represents the embodiment of the "unique cultural essence of cultural groups" and their right to develop cultural distinctiveness, irrespective of whether these groups seek an independent nation-state. ==Criticism==
