Member states of the Council of Europe

The Council of Europe was founded on 5 May 1949 by ten western and northern European states, with Greece joining three months later, and Iceland,  Turkey  and West Germany  joining the next year. It now has 46 member states, with Montenegro being the latest to join.

Article 4 of the Council of Europe Statute specifies that membership is open to any European country, provided they meet specific democratic and human rights standards. Nearly all countries with territory in Europe are members of the Council of Europe, with the exceptions of Belarus, Kazakhstan, Russia, and Vatican City, as well as states with limited recognition.

Applicants
Special Guest status with the Parliamentary Assembly was established in 1989, as a provisional status in the accession process for parliaments of European non-member states, which applied for membership in the Council of Europe. The aim of the special guest status is to foster closer relations with the national parliaments of the European non-member states, by enabling the parliament concerned to be represented in, and work with, the Assembly, especially in determining the accession conditions.

Belarus
Belarus applied for full membership on 12 March 1993, and its parliament held special guest status with the Parliamentary Assembly from September 1992 to January 1997. The special guest status was however suspended as a consequence of the November 1996 constitutional referendum upholding the death penalty, and parliament by-elections which the CoE found to be undemocratic, as well as enforced limits on democratic freedoms such as freedom of expression (cf. Belarusian media) under the administration of President Alexander Lukashenko. A second change of the Belarus constitution in October 2004, moreover "does not respect minimum democratic standards and violates the principles of separation of powers and the rule of law". In June 2009, PACE decided that the suspension of the Belarusian parliament's special guest status in the Assembly would only be lifted conditional of the government imposing a moratorium on the death penalty. As of May 2013, this condition had not been met.

Kazakhstan
Kazakhstan applied for the Special Guest status with the Parliamentary Assembly in 1999. The Assembly found that Kazakhstan could apply for full membership, because 4% of its territory, west of the Ural river, is located in Europe, but granting Special Guest status would require improvements in the fields of democracy and human rights. Kazakhstan signed a co-operation agreement with the Assembly in April 2004.

In November 2006, the Kazakhstan Parliament officially asked to be granted observer status with the Assembly, which however was never granted due to requiring a pre compliance with all CoE core values and principles. The country acceded to the Council of Europe's European Cultural Convention on 24 February 2010. On 15 to 16 March 2010, the President of the Council of Europe's Parliamentary Assembly (PACE) made an official visit to Kazakhstan, resulting in the conclusion that the Council of Europe and Kazakhstan strengthen their relations. This milestone emboldens Kazakhstan's "Path to Europe" programme, as outlined by Kazakh president Nursultan Nazarbayev in Astana in 2008.

In December 2013, a Joint Declaration on enhancing co-operation between Kazakhstan and the Council of Europe in 2014–15, was signed with the purpose of paving the way for Kazakhstan's accession to the Council of Europe's multiple conventions in the field of criminal justice.

Kosovo
Kosovo became a member of the Council of Europe Development Bank in 2013 and a member of the Council of Europe's Venice Commission in 2014. The Assembly of Kosovo was invited to take part in the work of the Parliamentary Assembly of the Council of Europe and its committees as an observer in 2016. Two representatives of local government in Kosovo participate in the work of the Congress of Local and Regional Authorities as observers.

Hashim Thaçi, Kosovo's Minister of Foreign Affairs, stated in December 2014 that an application for membership of the Council of Europe was planned to be filed within the first quarter of 2015. On May 12, 2022, Foreign Minister Donika Gërvalla-Schwarz submitted the application for membership at a meeting with the Council's leadership in Strasbourg. Kosovo is already de facto under the jurisdiction of the European Court of Human Rights. On 20 March 2023, Kosovar prime minister Albin Kurti said during a meeting with foreign diplomats in Pristina, that as a result of the Ohrid Agreement, approved by Kosovo and Serbia two days earlier, the road for Kosovo to join the Council of Europe was now open. On 24 April 2023, the Committee of Ministers of the Council of Europe approved Kosovo's application for membership with 33 votes in favour, 7 against and 5 abstentions, allowing the application to progress to the Parliamentary Assembly. Dora Bakoyannis of Greece was appointed as Rapporteur for Kosovo. Bakoyannis gave a statutory opinion at a meeting of the Committee on Political Affairs and Democracy of the Parliamentary Assembly of the Council of Europe on 27 March 2024. The opinion recommended that Kosovo be admitted as a "member" state of the council under Article 4 of its statute, as opposed to an "associate member" country under Article 5. It also stated that a footnote describing the status of Kosovo would no longer be required to be used within the work of the council and its associated bodies. The Committee on Political Affairs and Democracy agreed to accept the recommendation with 31 delegates voting in favour, four against and one abstention. On 15 April 2024, the Committee on Equality and Non-Discrimination supported Kosovo's application and the Committee on Legal Affairs and Human Rights confirmed that Kosovo met the legal definition of "European State" as defined by article 4 of the Statute of the Council of Europe and meets the criteria of statehood under international law. The following day, on 16 April 2024, the Parliamentary Assembly voted in favour of Kosovo's membership, with 131 votes in favour, 29 against and 11 abstentions. The final decision on membership is to be made by the Council of Europe’s Committee of Ministers at a later date.

Vatican City
Despite being in Europe, Vatican City has never applied for Council of Europe membership, choosing to become an observer instead. However, there have been calls for it to apply to become a contracting party to the European Convention on Human Rights.

Other countries
Observer status was designed for non-European democracies willing to contribute to democratic transitions in Europe.

Canada, Japan, Mexico, the U.S. and the Holy See have observer status with the Council of Europe and can participate in the Committee of Ministers and all intergovernmental committees. They may contribute financially to the activities of the Council of Europe on a voluntary basis.

The parliaments of Canada, Israel and Mexico have observer status with the Parliamentary Assembly and their delegations can participate in Assembly sessions and committee meetings. A deligation representing the Assembly of Kosovo has also been invited to participate the Parliamentary Assembly on an ad hoc basis. Representatives of the Palestinian Legislative Council may participate in Assembly debates concerning the Middle East as well as Turkish-Cypriot representatives from Northern Cyprus concerning the island.

There has been criticism concerning the observer status of Japan and the United States because both countries apply the death penalty. The Parliamentary Assembly has been lobbying for the United States and Japan to abolish the death penalty or lose their observer status. The Council also voted to restore Special Guest status to Belarus, on condition that Belarus declares a moratorium on the death penalty.

Partners
In May 2009, the Parliamentary Assembly established a new status for institutional co-operation with parliaments of non-member states in neighbouring regions wishing to be supported by the Parliamentary Assembly in their democratic transitions and to participate in the political debate on common challenges.

The new status is called "Partner for democracy" and interested states could obtain it if they commit to embrace the values of the Council of Europe such as pluralist democracy, the rule of law and respect for human rights and fundamental freedoms; to encourage a moratorium on executions and abolish the death penalty; to organise free and fair elections; to become party to the relevant CoE conventions; to utilise the expertise of the Assembly and the Venice Commission in its institutional and legislative work.

CoE has adopted the policy of dialogue with the neighbouring regions of the southern Mediterranean, the Middle East and Central Asia – based on respect for universal human rights. Following this policy the Assembly has already established working contacts with parliaments of neighbouring countries other than those of the CoE Observers: Algeria, Kazakhstan, Morocco, Tunisia and the Palestinian Legislative Council. Several of these parliaments have expressed interest in upgrading the status of the existing co-operation, and in establishing a relationship on a permanent basis.

Since 1994, parliaments of the countries bordering the Council of Europe member states have the possibility of concluding special co-operation agreements with the Assembly, but it has not generated much interest among the parliaments concerned, which suggests that it does not offer sufficient clarity and visibility. So far only the Kazakhstan Parliament had taken advantage of it since 2004.

In November 2006, the Kazakhstan Parliament officially asked to be granted observer status with the Assembly. Such formal or informal requests are made by a number of parliaments that are already co-operating with it but think that the institutionalised recognition of that co-operation could make it more visible, more coherent and more effective. However the observer status is considered inappropriate in these cases, as it requires that the state receiving it already complies with the CoE core values and principles, which is not the case for the states currently requesting it, who are in the early stages of democratic transition.

The newly established "Partner for democracy" status is similar to the co-operation initiatives of other intergovernmental organisations of mostly European states such as the European Neighbourhood Policy of the EU, the partners for co-operation of OSCE, the co-operation with non-member states of NATO.

The national parliaments eligible to request a "Partner for democracy" status are from the following countries:
 * southern Mediterranean and Middle East participants in the Union for the Mediterranean: Mauritania, Morocco, Algeria, Tunisia, Egypt, Israel, Jordan, Syria, Lebanon, Palestine and possibly Libya (Libya is observer of the Union for the Mediterranean)
 * Central Asian participants in the OSCE: Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan
 * other states if the Bureau of the Assembly so decides

As of 2024 the following parliaments have been accorded "Partner for democracy" status:
 * Morocco – June 2011
 * Palestinian National Council – 4 October 2011
 * Kyrgyzstan – 8 April 2014
 * Jordan - 26 January 2016
