Citizens of the European Union

Citizenship of the European Union was introduced by the Maastricht Treaty, which was signed in 1992, and has been in force since 1993. European Union citizenship is additional to national citizenship. The EU citizenship affords rights, freedoms and legal protections to its citizens.

Rights include the right to vote in and run as a candidate in local elections in a country where they live (but not presidential and parliamentary elections), European elections, European Citizens' Initiative, and the right to consular protection by other EU states' embassies when a person's country of citizenship does not maintain an embassy or a 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, and in their own language, given the issue raised is within its competence.

EU citizens' freedoms include 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.

EU citizens also enjoy legal protections of the EU law, specifically the Charter of Fundamental Rights of the European Union (aka. the Charter) 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.
