The Treaty of Amsterdam, officially the Treaty of Amsterdam amending the Treaty on European Union, the Treaties establishing the European Communities and certain related acts, was signed on 2 October 1997, and entered into force on 1 May 1999; [1] it made substantial changes to the Treaty of Maastricht, which had been signed in 1992.


Under the Treaty of Amsterdam, member states agreed to transfer certain powers from national governments to the European Parliament across diverse areas, including legislating on immigration, adopting civil and criminal laws, and enacting common foreign and security policy (CFSP), as well as implementing institutional changes for expansion as new member nations join the EU.


The treaty was the result of long negotiations which began in Messina, Italy, on 2 June 1995, nearly forty years after the signing of the Treaty of Rome, and reached completion in Amsterdam on 18 June 1997. Following the formal signing of the Treaty on 2 October 1997, the member states engaged in an equally long and complex ratification process. The European Parliament endorsed the treaty on 19 November 1997, and after two referendums and 13 decisions by parliaments, the member states finally concluded the procedure.


The Treaty of Amsterdam comprises 13 protocols, 51 declarations adopted by the Conference, and eight declarations by member states, plus amendments to the existing treaties set out in 15 articles. Article 1 (containing 16 paragraphs) amends the general provisions of the Treaty on European Union and covers the CFSP and cooperation in criminal and police matters. The next four articles (70 paragraphs) amend the EC Treaty, the European Coal and Steel Community Treaty (which expired in 2002), the Euratom Treaty, and the Act concerning the election of the European Parliament. The final provisions contain four articles. The new treaty also set out to simplify the Community Treaties, deleting more than 56 obsolete articles and renumbering the rest in order to make the whole more legible. By way of example, Article 189b on the codecision procedure became Article 251.

The most pressing concerns of ordinary Europeans, such as their legal and personal security, immigration, and fraud prevention, were all dealt with in other chapters of the treaty. In particular, the EU became responsible for legislating on immigration, civil law or civil procedure, insofar as this is necessary for the free movement of persons within the EU. At the same time, intergovernmental co-operation was intensified in the police and criminal justice field so that member states should be able to coordinate their activities more effectively. The Union aims to establish an area of freedom, security and justice for its citizens. The Schengen Agreements have now been incorporated into the legal system of the EU (Ireland remains outside the Schengen agreement due to its open border with the United Kingdom, see Common Travel Area for details).

The treaty lays down new principles and responsibilities in the field of the common foreign and security policy, with the emphasis on projecting the EU's values to the outside world, protecting its interests, and reforming its modes of action. The European Council will lay down common strategies, which will then be put into effect by the Council acting by a qualified majority, subject to certain conditions. In other cases, some member states may choose to abstain "constructively", i.e. without actually preventing actions being taken.

The treaty introduced a High Representative for EU Foreign Policy who, together with the Presidents of the Council and the European Commission, puts a "name and a face" on EU policy to the outside world. Although the Amsterdam Treaty did not provide for a common defence, it did increase the EU's responsibilities for peacekeeping and humanitarian work, in particular by forging closer links with Western European Union.


As for the institutions, there were two major reforms concerning the co-decision procedure (the legislative procedure involving the European Parliament and the council), affecting its scope—most legislation was adopted by the co-decision procedure—and its detailed procedures, with the parliament playing a much stronger role. The President of the commission will also have to earn the personal trust of the parliament, which will give them the authority to lay down the commission's policy guidelines and play an active part in choosing the Members of the commission by deciding on their appointment by common accord with the national governments. These provisions make the Commission more politically accountable, particularly vis-à-vis the European Parliament. Finally, the new Treaty enables, under very strict conditions, closer co-operation between member states which so wish. Closer co-operation may be established, on a proposal from the commission, in cases where it is not possible to take joint action, provided that such steps do not undermine the coherence of the EU or the rights and equality of its citizens.


The Amsterdam Treaty did not settle all institutional questions. Work was still in progress on reforming the institutions to make them capable of operating effectively and democratically in a much enlarged EU. The most pressing issues were the composition of the commission and the weighting of member states' votes upon qualified majority voting. These questions were addressed in the Treaty of Lisbon.

EU evolution timeline

Since the end of World War II, sovereign European countries have entered into treaties and thereby co-operated and harmonised policies (or pooled sovereignty) in an increasing number of areas, in the European integration project or the construction of Europe (French: la construction européenne). The following timeline outlines the legal inception of the European Union (EU)—the principal framework for this unification. The EU inherited many of its present responsibilities from the European Communities (EC), which were founded in the 1950s in the spirit of the Schuman Declaration.

  1. 1 2 3 4 5 Although not EU treaties per se, these treaties affected the development of the EU defence arm, a main part of the CFSP. The Franco-British alliance established by the Dunkirk Treaty was de facto superseded by WU. The CFSP pillar was bolstered by some of the security structures that had been established within the remit of the 1955 Modified Brussels Treaty (MBT). The Brussels Treaty was terminated in 2011, consequently dissolving the WEU, as the mutual defence clause that the Lisbon Treaty provided for EU was considered to render the WEU superfluous. The EU thus de facto superseded the WEU.
  2. Plans to establish a European Political Community (EPC) were shelved following the French failure to ratify the Treaty establishing the European Defence Community (EDC). The EPC would have combined the ECSC and the EDC.
  3. The European Communities obtained common institutions and a shared legal personality (i.e. ability to e.g. sign treaties in their own right).
  4. The treaties of Maastricht and Rome form the EU's legal basis, and are also referred to as the Treaty on European Union (TEU) and the Treaty on the Functioning of the European Union (TFEU), respectively. They are amended by secondary treaties.
  5. Between the EU's founding in 1993 and consolidation in 2009, the union consisted of three pillars, the first of which were the European Communities. The other two pillars consisted of additional areas of cooperation that had been added to the EU's remit.
  6. The consolidation meant that the EU inherited the European Communities' legal personality and that the pillar system was abolished, resulting in the EU framework as such covering all policy areas. Executive/legislative power in each area was instead determined by a distribution of competencies between EU institutions and member states. This distribution, as well as treaty provisions for policy areas in which unanimity is required and qualified majority voting is possible, reflects the depth of EU integration as well as the EU's partly supranational and partly intergovernmental nature.

The European Economic Community (EEC) was a regional organisation created by the Treaty of Rome of 1957, aiming to foster economic integration among its member states. It was subsequently renamed the European Community (EC) upon becoming integrated into the first pillar of the newly formed European Union in 1993. In the popular language, however, the singular European Community was sometimes inaccurately used in the wider sense of the plural European Communities, in spite of the latter designation covering all the three constituent entities of the first pillar.

The Treaty on European Union, commonly known as the Maastricht Treaty, is the foundation treaty of the European Union (EU). Concluded in 1992 between the then-twelve member states of the European Communities, it announced "a new stage in the process of European integration" chiefly in provisions for a shared European citizenship, for the eventual introduction of a single currency, and for common foreign and security policies, and a number of changes to the European institutions and their decision taking procedures, not least a strengthening of the powers of the European Parliament and more majority voting on the Council of Ministers. Although these were seen by many to presage a "federal Europe", key areas remained inter-governmental with national governments collectively taking key decisions. This constitutional debate continued through the negotiation of subsequent treaties, culminating in the 2007 Treaty of Lisbon.

<span class="mw-page-title-main">European Communities</span> International organizations governed by the same set of institutions

The European Communities (EC) were three international organizations that were governed by the same set of institutions. These were the European Coal and Steel Community (ECSC), the European Atomic Energy Community, and the European Economic Community (EEC); the last of which was renamed the European Community (EC) in 1993 by the Maastricht Treaty establishing the European Union. The European Union was established at that time more as a concept rather than an entity, while the Communities remained the actual subjects of international law impersonating the rather abstract Union, becoming at the same time its first pillar. In the popular language, however, the singular European Community was sometimes inaccurately used interchangeably with the plural phrase, in the sense of referring to all three entities.

An entity to be named the European Political Community (EPC) was proposed in 1952 as a combination of the existing European Coal and Steel Community (ECSC) and the proposed European Defence Community (EDC). A draft EPC treaty, as drawn up by the ECSC assembly, would have seen a directly elected assembly, a senate appointed by national parliaments and a supranational executive accountable to the parliament.

<span class="mw-page-title-main">Single European Act</span> Revision to the Treaty of Rome

The Single European Act (SEA) was the first major revision of the 1957 Treaty of Rome. The Act set the European Community an objective of establishing a single market by 31 December 1992, and a forerunner of the European Union's Common Foreign and Security Policy (CFSP) it helped codify European Political Co-operation. The amending treaty was signed at Luxembourg City on 17 February 1986 and at The Hague on 28 February 1986. It came into effect on 1 July 1987, under the Delors Commission.

The Merger Treaty, also known as the Treaty of Brussels, was a European treaty which unified the executive institutions of the European Coal and Steel Community (ECSC), European Atomic Energy Community (Euratom) and the European Economic Community (EEC). The treaty was signed in Brussels on 8 April 1965 and came into force on 1 July 1967. It set out that the Commission of the European Communities should replace the High Authority of the ECSC, the Commission of the EEC and the Commission of Euratom, and that the Council of the European Communities should replace the Special Council of Ministers of the ECSC, the Council of the EEC and the Council of Euratom. Although each Community remained legally independent, they shared common institutions and were together known as the European Communities. This treaty is regarded by some as the real beginning of the modern European Union.

Between 1993 and 2009, the European Union (EU) legally comprised three pillars. This structure was introduced with the Treaty of Maastricht on 1 November 1993, and was eventually abandoned on 1 December 2009 upon the entry into force of the Treaty of Lisbon, when the EU obtained a consolidated legal personality.

  1. The European Communities pillar handled economic, social and environmental policies. It comprised the European Community (EC), the European Coal and Steel Community, and the European Atomic Energy Community (EURATOM).
  2. The Common Foreign and Security Policy (CFSP) pillar took care of foreign policy and military matters.
  3. Police and Judicial Co-operation in Criminal Matters (PJCCM) brought together co-operation in the fight against crime. This pillar was originally named Justice and Home Affairs (JHA)

The Euratom Treaty, officially the Treaty establishing the European Atomic Energy Community, established the European Atomic Energy Community. It was signed on 25 March 1957 at the same time as the Treaty establishing the European Economic Community.

<span class="mw-page-title-main">European Political Co-operation</span> Former intergovernmental body

The European Political Co-operation (EPC) was the common term for the co-ordination of foreign policy between member states of the European Communities (EC) from its inception in 1970 until the EPC was superseded by the new European Union's (EU) Common Foreign and Security Policy (CFSP) pillar upon the entry into force of the Maastricht Treaty in November 1993.

The Davignon report, also referred to as the Luxembourg report, published on 27 October 1970, was a report on the future foreign policy of European Economic Community member nations. It was written by a council chaired by Étienne Davignon of the Belgian Foreign Office. The committee was appointed by the Council of the European Communities to make proposals on political cooperation between the member states. It recommended that member states should try to speak with a single voice on international problems, a proposal that was approved by all six member governments. It resulted first in European Political Cooperation and later in the European Union's Common Foreign and Security Policy in 1992.
