Citizenship of the European Union (EU) is afforded to qualifying citizens of European Union member states. It was introduced by the 1992 Maastricht Treaty and has been in force since 1993. European Union citizenship is additional to national citizenship. EU citizenship affords rights, freedoms and legal protections to all of its citizens.
European Union citizens have the right to free movement, settlement and employment across the EU. EU citizens are also free to trade and transport goods, services and capital through EU borders, as in national market, with no restrictions on capital movements or duty-fees. Citizens also have the right to vote in and run as a candidate in local elections in the country where they live, European elections and European Citizens' Initiative.
Citizenship of the EU also confers the right to consular protection by embassies of other EU member states when a person's country of citizenship is not represented by an embassy or consulate in the country in which they require protection. EU citizens also have the right to address the European Parliament, European Ombudsman, and EU agencies directly in their own language, given the issue raised is within its competence.
EU citizens also enjoy legal protections of the EU law, specifically the Charter of Fundamental Rights of the European Union and acts and directives regarding e. g. protection of personal data, rights of victims of crime, preventing and combating trafficking in human beings, equal pay, protection from discrimination in employment on grounds of religion or belief, sexual orientation and age. The EU also has an office of European Ombudsman whom EU citizens can approach directly.
EU citizenship was first introduced by the Maastricht Treaty, and was extended by the Treaty of Amsterdam. Prior to the 1992 Maastricht Treaty, the European Communities treaties provided guarantees for the free movement of economically active persons, but not, generally, for others. The 1951 Treaty of Paris establishing the European Coal and Steel Community established a right to free movement for workers in these industries and the 1957 Treaty of Rome provided for the free movement of workers and services.
