Significance

Signed at Maastricht in the Netherlands on 7 February 1992 by the twelve member states of the European Communities and entering into force on 1 November 1993, the Treaty on European Union created the European Union as a deeper political and economic entity built on the existing communities.

It introduced EU citizenship, a framework for a common foreign and security policy and cooperation in justice and home affairs, and committed members to Economic and Monetary Union, setting convergence criteria that paved the way for the single currency, the euro, launched in 1999. The treaty's ratification proved contentious: Danish voters initially rejected it before approving an amended version, and France endorsed it by a narrow margin. Maastricht reshaped European governance, transferring further authority to supranational institutions while granting the United Kingdom and Denmark opt-outs. It became the foundational document of the post-Cold-War European project, framing decades of subsequent integration, enlargement into former communist states, and recurring debate over the balance between national sovereignty and shared European institutions.
