Maastricht Treaty Timeline

(7 February 1991 – 1 November 1993)

The Maastricht Treaty, formally the Treaty on European Union, was signed on 7 February 1992 in Maastricht, Netherlands, by the twelve member states of the European Community. It established the European Union, created the three-pillar structure (European Communities, Common Foreign and Security Policy, Justice and Home Affairs), set out a roadmap for Economic and Monetary Union leading to the euro, introduced EU citizenship, and required ratification through national referendums or parliamentary votes. After challenges including Denmark's initial rejection, it entered into force on 1 November 1993. Less

Origins and Context

Establishment of the European Economic Community

1957

From the establishment of the European Economic Community in 1957, integrationists argued the free movement of workers was the logical corollary of the free movement of capital, goods and services and integral to the establishment of a common (and later single) European market.

Coordination begins under European Political Cooperation

European Monetary System agreed

1978

The European Monetary System (EMS) was agreed in 1978 as a means of reducing the "barrier" that exchange-rate volatility presented for intra-Community commerce (and for the management of payments under the Common Agricultural Policy). Its Exchange Rate Mechanism (ERM) was its centrepiece.

German reunification sought by Chancellor Kohl

High German interest rates strain the ERM

Beginning in 2009 with Greece, the governments of several Euro-zone countries (Portugal, Ireland, Spain and Cyprus) declared themselves unable to repay or refinance their government debt or to bail out over-indebted banks without third-party assistance. The Maastricht criteria became the most enduring reference point for rules of compliance in the currency union, and the constraints became a focus of political scrutiny and public protest.
