Religious nationalism can be understood in a number of ways, such as nationalism as a religion itself, a position articulated by Carlton Hayes in his text Nationalism: A Religion, or as the relationship of nationalism to a particular religious belief, dogma, ideology, or affiliation. This relationship can be broken down into two aspects: the politicisation of religion and the influence of religion on politics.
In the former aspect, a shared religion can be seen to contribute to a sense of national unity, a common bond among the citizens of the nation. Another political aspect of religion is the support of a national identity, similar to a shared ethnicity, language, or culture. The influence of religion on politics is more ideological, where current interpretations of religious ideas inspire political activism and action; for example, laws are passed to foster stricter religious adherence.
