Relationships among law, religion, ethics, and politics are a subject matter for research­es on both theory of law and comparative law. Different legal cultures have their specific features concerning correlation between law and other social norms. Some legal systems are based on the rule of law and other prioritise religious principles. These contradictionsacquire special relevance in Europe with the emergence of Muslim minorities. Legal mea­sures taken to solve these contradictions are inefficient to overcome tense conflicts causedby a still growing role of Islam in some European countries.
