The close connection between "interculturality" and "dialogue" constitutes the fil rouge of the reflection on diversity inclusion policies, represented by the syntagm "intercultural dialogue". The analysis of the legal-political instruments of institutional dialogue - provided for both in the Italian legal system in the relationship with religious denominations, and in the law of the European Union - as well as the forms of dialogue on human rights or inter-religious dialogue allow us to deepen the peculiarity that distinguishes "intercultural dialogue" from other forms of dialogue and interaction, precisely by virtue of its potential to integrate differences. The process of inclusion of diversity triggered by "intercultural dialogue" also increasingly invests the legal field with a view to training future legal practitioners equipped to meet the challenges posed by multi-religiousness and interculturality. In this perspective, the knowledge of religious rights constitutes one of the new frontiers of legal knowledge in function of a fruitful 'dialogue between rights' that is realised through the interpretation of the legal datum in an intercultural sense, in order to build a concrete cohesive society, respectful of the principles of freedom and equality in diversity that constitute the fundamental principles of Western constitutionalism.
