Ayaş had been inhabited since the ancient ages. Ancient Ayas was an island named Elaiussa and a town on the shore facing the island named Sebaste.
Archelaus of Cappadocia had a palace in Elaiussa. But the island had since been joined the mainland because of alivion accumulation. During middle age, Elaiussa Sebaste lost its former importance. After the 12th century, the ruins of the former town became a battle ground between the
Armenian Kingdom of Cilicia and the
Karamanids. The area around the former town was incorporated into
Ottoman Empire in the 15th century and it became the grazing area of a nomadic
Turkmen tribe named Ayaş. A part of the tribe settled in the village named after Ayaş and, in 1989, it was incorporated into
Kumkuyu municipality on the east. In 1999, Ayaş was declared a town and issued from Kumkuyu municipality. == Economy ==
