The Edomites entered Judah after the Assyrian conquest and exploited the territory. They suffered greatly at the hands of the Babylonians during the early 6th century BC. Although the Edomite capital Buseirah (in Jordan) has yielded little information, evidence of Edomite presence in Judah is extensive:
Edomite fortresses, including Ein Hazeva.
Edomite ostraca, mostly found in southern sites.
Via seals and letters, Edomite names had the theophoric element Qaus.
Edomite Qaus figurines have also been found.
