What happened
The European Council recognized Turkey as an official candidate for European Union membership in 1999, and accession negotiations formally opened on 3 October 2005. Progress has been limited from the start: under the terms set at the time, eight negotiating chapters cannot be opened and none can be provisionally closed until Turkey applies the Ankara Association Agreement's additional protocol to Cyprus, a member state Turkey does not recognize. By 2018, the European Commission concluded that continuing backsliding on democratic reforms, fundamental rights, and judicial independence had brought accession negotiations to an effective standstill, and as of the Commission's own current accounting only 15 of the 35 negotiating chapters are open, with a single chapter provisionally closed.
Why it matters
Turkey's EU candidacy, still formally open after more than two decades, illustrates how the country's Western institutional integration, secured decisively through NATO membership in 1952, has not extended to the European Union, both because of the unresolved Cyprus dispute this timeline also covers and because of the European Commission's own assessment of democratic backsliding inside Turkey. The stalled process remains one of the clearest measures of the distance between Ataturk's original Western-facing republic and Turkey's current relationship with Europe.
How we know
Turkey's EU candidate status, the 2005 opening of accession talks, and the 2018 assessment that negotiations had stalled are documented directly by the European Commission's own enlargement policy pages, which track the number of negotiating chapters opened and closed in real time.
