The European Movement is an international organization open to all political, economic, social and cultural trends in civil society. Its objective is to "contribute to the establishment of a united, federal Europe founded on the principles of peace, democracy, liberty, solidarity, and respect for basic human rights. It seeks to provide a structure to encourage and facilitate the active participation of citizens and civil society organizations in the development of a united Europe". Its 42 National Councils and 32 associated Member Organizations work towards bringing together representatives from European associations, political parties, enterprises, trade unions and individual lobbyists. The European Movement has a very rich history involving very high level political figures crucial for European integration such as Walter Hallstein and Robert Schuman.
