1 Euro

Cyprus adopted the euro on 1 January 2008, having been admitted to the Eurozone despite its unresolved territorial division — the northern third of the island remains under Turkish military occupation following the 1974 invasion, and the currency technically circulates only in the southern Republic. That political anomaly made Cyprus one of the few euro adopters where the issuing authority governs a geographically partitioned state, a situation the European Central Bank acknowledged but did not treat as a barrier to accession.
