The majority of the Arabs in Singapore are Hadharem and traced their ancestry to the southern Arabian Peninsula in Hadramaut, Yemen. The valley region was part of a confederacy once ruled by the Queen of Sheba. Hadramaut was mentioned in The Old Testament (Hazra Mavet). Its fertile areas, suitable for cultivation, had beguiled ancient Romans to call it, and all South Arabia in general, Arabia Felix (Happy Arabia).
There is an extensive history of migration from Hadramaut with migrants often migrating for business and religious missionary-related causes as done before the mid-19th century, however the migration increased significantly following the monsoons of the Indian Ocean, war and economic crisis in Yemen, forced the Hadhramis to resettle in various parts of the world: Hyderabad, India (before 1947), Dar-es-Salaam and East Africa as well as Malaya and the Netherlands East Indies.
