İzmir has more than 3,000 years of recorded urban history, and up to 8,500 years of history as a human settlement since the Neolithic period. In classical antiquity the city was known as Smyrna ( ; ) – a name which remained in use in English and various other languages until around 1930, when government efforts led the original Greek name to be gradually phased out internationally in favor of its Turkish counterpart . Lying on an advantageous location at the head of a gulf running down in a deep indentation, midway along the western Anatolian coast, İzmir has been one of the principal mercantile cities of the Mediterranean Sea for much of its history. It hosted the Mediterranean Games in 1971 and the World University Games (Universiade) in 2005. The city participated in Climathon in 2019.
