 In inscriptions and coins, the name often was written as ("Zmýrna"), ("Zmyrnaîos", "of Smyrna").The name "Smyrna" may also have been taken from the ancient Greek word for myrrh, "smýrna", which was the chief export of the city in ancient times.The region was settled at least as of the beginning of the third millennium BC, or perhaps earlier, as suggested by finds made in Yeşilova Höyük in excavations since 2005.
