The Council of Europe was founded by ten northern and western European states. It received its formal statute on 5 May 1949 from Belgium, Denmark, France, Ireland, Italy, Luxembourg, the Netherlands, Norway, Sweden and the United Kingdom in the London Ten-Power Pact. It is thus the oldest original political organisation of European states. It was founded by the European Conference on Federation at the instigation of the American Committee for a United Europe.
In addition to the economic OEEC (merged into the OECD) and military cooperation within the framework of NATO, the political unification of the continent took concrete shape with the Council of Europe.
The Federal Republic of Germany joined the body on 14 July 1950, initially as an associate member, and became a full member in May 1951. The Saarland (an autonomous state until 1 January 1957) was already an associate member on 13 May 1950 and a full member from 2 May 1951. Austria attained membership in 1956, and Switzerland in 1963.
All but three European states now belong to the Council of Europe. As such, the Vatican City State does not enter into relations with other states, but leaves its representation at the international level to the Holy See - the latter, as a non-state subject of international law, has observer status in the Committee of Ministers. Belarus has been a candidate country since 1993. Kosovo will only be considered for membership once its status has been clarified under international law. Until then, Kosovo has been granted observer status since April 2013 through two representatives of the Kosovar parliament, who can participate in the debates of the plenary sessions and in the work of the committees without voting rights.
Following the controversial vote on Crimea's affiliation to Russia, the Council of Europe provisionally withdrew the voting rights of the 18 Russian deputies in April 2014 by a majority of 145 votes to 21 with 22 abstentions. In addition, Russia is excluded from the governing bodies of the Assembly until further notice, whereupon the Russian deputies boycotted the meetings of the Assembly from then on and Russia also stopped paying its membership fees from June 2017 until further notice.
Because the withdrawal of voting rights was not regulated in the Council of Europe's statutes, and because after two years without paying dues Russia was threatened with permanent expulsion and an election of the organization's next secretary-general without Russian members in the Parliamentary Assembly, the Council of Ministers decided on 17 May 2019, on the initiative of the Finnish presidency, to introduce a new multi-stage procedure for sanctioning members to pave the way for Russia's renewed full membership.
