Before the 1990 Yemeni unification, the region had never been united as one country. In order to create unity and overcome sectarianism, the myth of Qahtanite was used as a nationalist narrative. Although not all ethnic groups of Yemen fit in this narrative, such as the Al-Akhdam and the Teimanim. The latter established a Jewish kingdom in ancient Yemen, the only one ever created outside Palestine. A massacre of Christians, executed by the Jewish king Dhu Nuwas, eventually led to the fall of the Homerite Kingdom. In modern times, the establishment of the Jewish state resulted in the 1947 Aden riots, after which most Teimanim left the country during Operation Magic Carpet.
