The Anteimoro, last of the overseas migrants to settle in Madagascar, conclude the essential formation of the Malagasy people. From genealogies and early European accounts, it is estimated that two initial contingents of the Anteimoro reached Madagascar around 1490 and settled at Matitana by 1512. The last and final one arrived by 1540. As a group, the Anteimoro were able to impose their own political and social structure on the tompontany of Matitana. Through intermarriage, the Anteimoro adopted the Malagasy language while moving toward endogamy to preserve their distinct identity as well as aristocratic position.
Alone in Madagascar, the Anteimoro developed a scribal tradition, manifested in countless Arabico-Malagasy Sora-bé manuscripts. One appears to antedate the 1600s, most were composed in the nineteenth century, but some are undoubtedly copies of earlier Sora-bé. An old Anteimoro vocabulary reveals a much higher percentage of Arabic words than are found today. While Islam is now extremely diluted among them, due to the complete isolation of the Anteimoro, there is no doubt that they were once zealotic Muslims.
The problem of their origin, explored by Grandidier, Ferrand and Julien, has been suspended between Arabia and the Swahili coast. Neither can be accepted. At least one genealogy shows a ‘pause’ of ten generations between the great ancestor of the Anteimoro in Madagascar and the last descendant of a line that had fled from Arabia. While there is no plausible alternative for this ‘pause’ other than Africa, the Swahili coast must be discounted in the absence of any architecture among the Anteimoro and of Swahili loan-words, phonemes and calligraphy. Attempts to see the etymon of Anteimoro (phon. temūrū) as Malagasy or as Swahili ‘Mahūrū’ (slaves) are also unsatisfactory. Imperfect as it may be, partial evidence points to Temur, a people of eastern or southern Ethiopia who vanished locally in the fifteenth century. It is also suggested that there were connexions with the Qadiriyya tarika, which Anteirnoro religious specialists sought to extend into Madagascar without success.
