Gerrha and Uqair are archaeological sites on the eastern coast of the Arabian Peninsula. Prior to Gerrha, the area belonged to the Dilmun civilization, which was conquered by the Assyrian Empire in 709 BCE. Gerrha was the center of an Arab kingdom from approximately 650 BCE to circa 300 CE. The kingdom was attacked by Antiochus III the Great in 205-204 BCE, though it seems to have survived. It is currently unknown exactly when Gerrha fell, but the area was under Sassanid Persian control after 300 CE.
