One of NATO's oldest member states, Turkey, has notified the alliance of its official name change to "Türkiye."
Turkey's Permanent Mission to NATO last week sent a letter to NATO Secretary-General Jens Stoltenberg to use the name Türkiye in place of foreign versions of the name.
European Union institutions were also informed about the country's new standard name.
Turkey is a longstanding member of NATO, having joined in 1952. This February, Turkey marked its 70th anniversary of NATO membership.
The move is meant to cement Turkey's brand name on the international stage and also more accurately reflect its heritage, according to officials.
At the U.N., the country's internationally recognized name has been changed from Turkey to Türkiye, said President Recep Tayyip Erdoğan on Monday.
After chairing a Cabinet meeting in the capital Ankara, Erdoğan said that under the official change, from now on all Turkish state institutions are using the name Türkiye in their correspondence.
He underlined that Turkey is an independent country that can determine and implement its own political and security priorities.
"Turkey is a country that is able to develop its own social policies and practice them as a strong country," said Erdoğan.
The shift to "Türkiye" at the U.N. comes in line with a request by Ankara, which the U.N. announced on June 1.
Speaking to Anadolu Agency (AA), U.N. spokesperson Stephane Dujarric said Secretary-General Antonio Guterres got a letter from Foreign Minister Mevlüt Çavuşoğlu requesting the use of "Türkiye" instead of "Turkey."
Military drill
Meanwhile, NATO will hold a military exercise in Turkey from June 20-28, the Turkish Defense Ministry announced Monday.
Ramstein Dust II-2022 (RADU II-22), a NATO deployment and readiness exercise, will be held at the third Main Jet Base Command in Konya.
The ministry added that the exercise is planned to be held in conjunction with the International Anatolian Eagle-2022 training exercise.
