When was the country Turkey discovered?

Answer 1

Humans first arrived in Turkey over 100,000 years ago. The first settled town in the world Çatal Hüyük (from 8500 B.C.E.) has been found in Turkey. Anatolia (the Asian part of Turkey) was also the seat of the Hatti and Hittite peoples during the Biblical Period. Western Turkey became part of the Aegean World, holding the famed cities of Troy, Ephesus, and Pergamon, and, of course, Constantinople/Istanbul. The "country" of Turkey was settled and continuously occupied long before the Age of Discovery.

As concerns the Republic of Turkey, that was founded by Mustafa Kemal Atatürk on September 18, 1922 and was officially declared on October 29, 1923. The Republic of Turkey was formed on the discarded ruins of the Ottoman Empire.

Answer 2

Turkey has had people living in that area for many thousands of years. It is not know who the original discoverer was. That fact has been lost to history.
