It was hoped that Cyprus would join as a unified island. However, northern Cyprus has remained outside the control of the internationally recognised government of the Republic of Cyprus since the Turkish invasion of 1974. The Annan Plan for the resolution of the Cyprus dispute was rejected by Greek Cypriots in a 2004 referendum. The accession treaties were signed on 16 April 2003 in Athens, admitting Malta, Cyprus, Slovenia, Estonia, Latvia, Lithuania, Poland, the Czech Republic, Slovakia, and Hungary. Romania and Bulgaria were not among the 10 chosen to accede in 2004.
