The end of the Cold War, German reunification, and the prospect of accelerating globalisation created pressure among European Communities member states to deepen integration. Tensions arose between those seeking a federal structure and those wishing to preserve national sovereignty, setting the context for a major constitutional negotiation.
In February 1992, the twelve member states of the European Communities signed the Treaty on European Union in Maastricht, Netherlands. The treaty formally created the European Union, established shared European citizenship, committed members to eventual monetary union, outlined common foreign and security policies, and strengthened the European Parliament's powers.
The treaty triggered the first major EU ratification crisis and sparked an ongoing constitutional debate resolved only by the 2007 Treaty of Lisbon. Its 'Maastricht criteria' for currency union compliance became particularly prominent after the Eurozone debt crisis that began in 2009, shaping economic policy discourse across member states for years.
Political Outcome
The European Union was formally established, with shared citizenship, a pathway to a single currency, and enhanced supranational institutions, though key areas of foreign and security policy remained intergovernmental.
