Alyattes, king of Lydia (619–560 BCE), considered to be the founder of the Lydian empire, is the son of Sadyattes, of the house of the Mermnadae.
For several years he continues the war against Miletus begun by his father, but is obliged to turn his attention towards the Medes and Babylonians.
On May 28, 585 BC, during the Battle of Halys fought against Cyaxares, king of Media, a solar eclipse takes place (see also Thales); hostilities are suspended, peace concluded, and the Halys fixed as the boundary between the two kingdoms.
Alyattes drives the Cimmerians from Asia Minor, subdues the Carians, and takes several Ionian cities (including Smyrna, Colophon).
(Smyrna is sacked and destroyed with its inhabitants forced to move into the countryside.)
He standardizes the weight of coins (1 Stater = 168 grains of wheat).
The coins are produced using an anvil die technique and stamped with the Lion's head, the symbol of the Mermnadae.
He is succeeded by his son Croesus.
His daughter Aryenis of Lydia is Queen consort of Astyages, King of Media.
His tomb still exists on the plateau between Lake Gygaea and the river Hermus to the north of Sardis—a large mound of earth with a substructure of huge stones.
It was excavated by Spiegelthal in 1854, who found that it covered a large vault of finely cut marble blocks approached by a flat-roofed passage of the same stone from the south.
The sarcophagus and its contents had been removed by early plunderers of the tomb.
All that was left were some broken alabaster vases, pottery and charcoal.
On the summit of the mound were large phalli of stone.
