The Republic of Cyprus is the sole internationally recognized government of the entire island. It is a member of the United Nations, European Union, Council of Europe, and Commonwealth of Nations.
De facto division: Since 1974, the Republic controls the southern ~60% of the island. The northern ~40% is administered by the Turkish Republic of Northern Cyprus (TRNC), a self-declared entity recognized only by Turkey. The "Green Line" buffer zone is patrolled by UNFICYP.
All foreign embassies, international treaties, and EU acquis apply to the Republic of Cyprus. The TRNC operates with Turkish support but lacks international legal personality.
