The relationship between the public sphere and religion is one of the great classics of the history of humanities. To this day, it has lost none of its topicality. Sociologists and political scientists continue to refer with great frequency to a return of religions to the public sphere. In the course of secularisation, globalisation and digitalisation, modern public spheres and religions find themselves in an increasingly complex web of mutual transformation. Public education and university research represent two key issues of this intensive interrelation. The contributions collected in the present volume illuminate selected aspects of this broad field from the end of the 18th century to the present.
