History of Ancient Arabia
Rise of the Himyarites Kingdom of Sana, 115 A.D. The breakdown of Ma’rib Dam → each breach made calamity-stricken tribes to migrate northward
The last emperor (Dhu Nawas) was killed in 525 A.D. by the army of King of Abyssinia on the request on Byzantium King
The collapse of Ma’rib dam is important. With each breach of the dam, some part of the population had to migrate northward.
Here in the north, nomads already live. The migration led to small wars between the natives and the migrated.
Ultimately, the natives started fighting among themselves too. This is the start of ‘Jahiliya’ Period.
