The European Students' Union (ESU) is an umbrella organisation of 45 National Unions of Students (NUS) from 40 countries. The NUSes are open to all students in their respective country regardless of political persuasion, religion, ethnic or cultural origin, sexual orientation or social standing. Our members are also student-run, autonomous, representative and operate according to democratic principles. The aim of ESU is to represent and promote the educational, social, economic and cultural interests of students at the European level towards all relevant bodies and in particular the European Union, Bologna Follow Up Group, Council of Europe and UNESCO.
