Though awareness for linguistic diversity is a policy target, the language rights of speakers of regional, minority, lesser-used and migrant languages are not legally protected. In the European Union, language policy is the responsibility of member states and European Union does not have a "common language policy." Based on the "principle of subsidiarity", European Union institutions play a supporting role in this field, promoting cooperation between the member states and promoting the European dimension in their language policies, particularly through the teaching and dissemination of their languages. The content of educational systems is the responsibility of individual member states and the European Union has very limited influence in this area. However, a number of European Union funded programmes actively promote language learning, most prominently under the much wider Lifelong learning Programme 2007–2013. Though regional and minority languages can benefit from European Union programmes, protection of linguistic rights is a matter for the member states.
