Maastricht Treaty Signed: Birth of the European Union

Twelve European nations signed the Maastricht Treaty on February 7, 1992, and created something that had never existed before: a political and economic union of sovereign states sharing a common citizenship, a planned common currency, and coordinated foreign and security policies. The treaty transformed the European Economic Community, a trade bloc focused on tariffs and market regulation, into the European Union, an entity with ambitions that extended far beyond commerce. The momentum for deeper integration had been building since the fall of the Berlin Wall in November 1989. German reunification raised old anxieties about a dominant Germany at the center of Europe. French President Francois Mitterrand and German Chancellor Helmut Kohl pushed for a monetary union partly as a way to bind Germany irreversibly into European structures, ensuring that German economic power would be exercised through shared institutions rather than unilateral action. The logic was explicitly political: countries that share a currency do not go to war with each other. The treaty established three "pillars" of European governance. The first expanded the existing European Community’s supranational powers over trade, competition, agriculture, and environmental policy. The second created a Common Foreign and Security Policy for coordinating diplomatic and military action. The third covered Justice and Home Affairs, including immigration, asylum, and police cooperation. The treaty also established criteria for Economic and Monetary Union, requiring member states to meet strict targets on inflation, government debt, and exchange rate stability before adopting the planned common currency. Ratification proved turbulent. Danish voters rejected the treaty in a June 1992 referendum, sending shockwaves through European capitals. France approved it by a razor-thin 51 percent margin in September. Britain negotiated opt-outs from the single currency and social policy provisions. The treaty finally entered into force on November 1, 1993. The euro was launched in 1999 and entered physical circulation in 2002. The EU expanded from twelve to twenty-seven members before Britain’s departure in 2020 tested whether the union Maastricht built could survive the loss of a major member.
