During the Dilmun era (from ca. 3000 BC), Failaka was known as "Agarum", the land of Enzak, a great god in the Dilmun civilization according to Sumerian cuneiform texts found on the island. As part of Dilmun, Failaka became a hub for the civilization from the end of the 3rd to the middle of the 1st millennium BC. Failaka was settled following 2000 BC after a drop in sea level. After the Dilmun civilization, Failaka was inhabited by the Kassites of Mesopotamia, and was formally under the control of the Kassite dynasty of Babylon. Studies indicate traces of human settlement can be found on Failaka dating back to as early as the end of the 3rd millennium BC, and extending until the 20th century AD. Many of the artifacts found in Falaika are linked to Mesopotamian civilizations and seem to show that Failaka was gradually drawn toward the civilization based in Antioch.
