Abbasid Expeditions To East Africa

Two or three Abbasid expeditions to East Africa are mentioned in the late Arabic ''Book of the Zanj''. The Abbasid caliphs al-Manṣūr (754–775), Hārūn al-Rashīd (786–809) and al-Maʾmūn (813–833) are reputed to have sent punitive expeditions to the Islamized city-states of the Somali coast and set up governors there.Ali Abdirahman Hersi, ''The Arab Factor in Somali History: The Origins and the Development of Arab Enterprise and Cultural Influences in the Somali Peninsula'', Ph.D. diss. (University of California at Los Angeles, 1977), pp. 111–112.H. Neville Chittick, "The East Coast, Madagascar and the Indian Ocean", in J. D. Fage and R. Oliver (eds.), ''The Cambridge History of Africa, Volume 3: From c.1050 to c. 1600'' (Cambridge University Press, 1977), pp. 183–231, at 194–195 and 198. The ''Book of the Zanj'' does not survive in any copy earlier than the 20th century and its historical reliability is highly questionable for the early Islamic period.Gervase Mathew, "The East African Coast until the Coming of the Portuguese", in R. Oliver and G. Mathew (eds.), ''History of East Africa'', Volume 1 (Clarendon Press, 1963), pp. 94–127, at 102.

The 9th-century writer al-Jāḥiẓ records an Omani expedition to East Africa in the late 7th century, but it was defeated.Felix Chami, Françoise Le Guennec-Coppens and Sophie Mery

Both the ''Book of the Zanj'' and the '' Pate Chronicle'', which places it slightly later in 696–697, attribute the arrival of Syrian Muslims to caliphal initiative.James McL. Ritchie and Sigvard von Sicard (eds.), ''An Azanian Trio: Three East African Arabic Historical Documents'' (Brill, 2020), pp. 78–80.Anna Rita Coppola, "Swahili Oral Traditions and Chronicles", in Stephanie Wynne-Jones and Adria LaViolette (eds.), ''The Swahili World'' (Routledge, ), pp. 147–155, at 150–151. The inhabitants of the coast accepted Islam and agreed to pay the '' kharāj'' to the caliphs. The Abbasids, who took over from the Umayyads in 750, sent an emissary, Yahya ibn ʿUmar al-ʿAnazī, to the East African cities in 765–766. Mohamed Haji Mukhtar, "Islam in Somali History: Fact and Fiction", in Ali Jimale Ahmed (ed.), ''The Invention of Somalia'' (The Red Sea Press, 1995), pp. 29–42, at 3–4.Mohamed Haji Mukhtar, ''Historical Dictionary of Somalia'', new ed. (The Scarecrow Press, 2005), p. xxvi. Abdurahman Abdullahi, ''Making Sense of Somali History'', Volume 1 (Adonis and Abbey, 2017), pp. 51–52. The sultans of Mogadishu, Mārka, Barāwa, Faza, Sīwī, Bata, Manda (Munda), Ṭaqa, Lamu (Āmu), Ūzi, Malindi (Malūdi), Uyūmba, Kilifi, Basāsa, Zanzibar, Kilwa and Waybu (possibly a tributary of the Shebelle) are among those who accepted the emissary. Gervase Mathew dates this to 766–767 and considers it a military expedition.

In 804, according to the ''Book'', the Zanj (''Zunūj'') refused to pay the ''kharāj'' and Hārūn sent an emir with soldiers against them. He replaced the Arab ''wālī''s (governors) with Persians from Shīrāz in every village from Mogadishu to Kilwa. The ''Pate Chronicle'' also mentions Hārūn sending the Persians.H. Neville Chittick, "Kilwa and the Arab Settlement of the East African Coast", ''The Journal of African History'' 4-2 (1963), pp. 179–190, at 181: "Expeditions were, we are told, subsequently sent to the East African coast by the Abbasid Caliphs al-Mansūr, Hāruū al-Rashīd and al-Mamūn in the second half of the eighth century A.D. and beginning of the ninth to quell revolts." The Persians were loyal for many years, but they stopped sending the ''kharāj'' even during the reign of Hārūn and entered open rebellion during the ''Miḥna'' of al-Maʾmūn, when he espoused the createdness of the Quran. The Zanj sent a manifesto to Baghdad and the caliph sent an army of 50,000 (raised either in Iraq or Egypt) to Malindi, which caused the leaders of the rebellion to flee into the ''nyika'' (brush country). They returned when the army left, but paid the outstanding ''kharāj'' and accepted the opinion of al-Maʾmūn. The ''Book of the Zanj'' dates these events to 837–838, which is not consistent with the reign of al-Maʾmūn.

According to Neville Chittick, these accounts in the ''Book of the Zanj'' must be given up as mythical. Archaeological evidence does not support extensive Arab or Persian settlement in these places at so early a date. He notes, however, that a gold ''dinar'' of Hārūn al-Rashīd dated to 798 or 799 has been found at Pemba, which is usually identified with the ''Qanbalū'' of Arabic sources. He suggests that if the accounts in the ''Book of the Zanj'' bear any relation to history it is probably to be found in the early settlement of Muslims on the East African coast associated with this coin find. Felix Chami et al. cast doubt on any Arab expeditions to East Africa after that recorded by al-Jāḥiẓ.
