Archaeology has revealed the existence of many civilizations in pre-Islamic Arabia (such as the Thamud), especially in South Arabia. South Arabian civilizations include the Sheba, the Himyarite Kingdom, the Kingdom of Awsan, the Kingdom of Ma'īn and the Sabaean Kingdom. Central Arabia was the location of the Kingdom of Kindah in the 4th, 5th and early 6th centuries AD. Eastern Arabia was home to the Dilmun civilization. The earliest known events in Arabian history are migrations from the peninsula into neighbouring areas.
