Religion has historically played an important role in shaping public order in Europe, influencing legal frameworks, cultural norms, and social policies. This proposal aims to examine how religious traditions, values and institutions have contributed to the development of public order in the European Union, while highlighting the tensions that arise in a pluralistic and secularised context. By analysing the interplay between religious freedoms, state neutrality and social cohesion, this proposal will seek to explore key issues such as the accommodation of different faiths, the limits of religious expression and the role of religion in public life.
