Sandakšatru

According to Herodotus, this movement started when the Massagetae[4] or the Issedones[5] migrated westwards, forcing the Scythians to the west across the Araxes[6] and into the Caspian Steppe,[5][4] from where they displaced the Cimmerians.

[6] Under Scythian pressure, the Cimmerians migrated to the south through the Klukhor [ru], Alagir and Darial passes in the Greater Caucasus mountains and reached Western Asia, where they would remain active for much of the 7th century BC.

After Tugdammi died of disease in 640 BC, Sandakšatru succeeded his father as the king of the western Cimmerian horde.

[11][5] In 637 BC, Sandakšatru's Cimmerians participated in another attack on Lydia, this time led by the Treres under their king Kōbos, and in alliance with the Lycians.

[18] The remnants of the Cimmerians were eventually assimilated by the populations of Anatolia,[5] and they completely disappeared from history after their defeat by Madyes and Alyattes.
