Postnationalism is the process or trend by which nation states and national identities lose their importance relative to supranational and global entities. Several factors contribute to its aspects including economic globalization, a rise in importance of multinational corporations, the internationalization of financial markets, the transfer of socio-political power from national authorities to supernational entities, such as multinational corporations, the United Nations and the European Union and the advent of new information and culture technologies such as the Internet. However attachment to citizenship and national identities often remains important.
