This chapter examines two important developments in the history of the European Union (EU): the signing of the Maastricht and Amsterdam Treaties. In June 1989, the European Council agreed to European Commission President Jacques Delors’s three-stage plan for monetary union by 1999, despite British opposition. In 1991, intergovernmental conferences (IGCs) were held on both monetary union and political union. The proposals of these IGCs were incorporated into the Treaty on European Union (TEU), agreed at Maastricht in December 1991. The TEU marked a major step on the road to European integration. It committed most of the member states to adopting a single currency and introduced the concept of European citizenship, among others. This chapter considers the events leading up to the signing of the TEU, from the Maastricht negotiations to the issue of enlargement, the 1996 IGC, and the Treaty of Amsterdam.
