The Isaaq clans began migrating from their ancestral homeland in the city of Maydh, eventually settling and dispersing across various regions of the Horn of Africa. These migrations were part of the broader movements of the Somali people around the Horn, which contributed to the establishment of Somali settlements in their present-day territories.
Overview The Isaaq people traditionally claim to have descended from Sheikh Ishaaq bin Ahmed, an Islamic scholar who purportedly traveled to Somaliland in the 12th or 13th century and married two women; one from the local Dir clan. and the other from the neighboring Harari people.I.M. Lewis, A Modern History of the Somali, fourth edition (Oxford: James Currey, 2002), pp. 31 & 42 He is said to have sired eight sons who are the common ancestors of the clans of the Isaaq clan-family. He remained in Maydh until his death.
Somali genealogical tradition and historical accounts places the origin of the Isaaq tribe in the 11th or 12th, century with the arrival of the Sheikh Ishaaq Bin Ahmed (Sheikh Ishaaq) from Arabia. Muhammad ibn Hassan Al Basri, Who was a near contemporary of Sheikh Ishaaq After his settlement in Maydh, Wrote a book compiling stories and poems about him, Which was referenced by the Hashemite scholar Imam Muhammad ‘Azza Ad Din Al Gherbani in his book “Al-‘Asjad al-manẓūm fī al-tārīkh wa al-‘ulūm. Makhtūṭat sīrat al-Sharīf Isḥāq ibn Aḥmad fī al-Yaman wa al-Ṣūmāl”, Better known as the Gherbani Manuscript in the 19th century. |title=العسجد المنظوم في التاريخ والعلوم: مخطوطة سيرة الشريف إسحاق ابن أحمد في اليمن والصومال |author=Muhammad ‘Azza Ad Din Al Gherbani |url=https://archive.org/details/20221001_20221001_0326/mode/1up |website=Internet Archive |accessdate=31 January 2026 Sheikh Ishaaq settled in the coastal town of Maydh in modern-day northeastern Somaliland.Hence, Sheikh Ishaaq married two local women in Somaliland, which left him with eight.
There are also numerous existing hagiographies in Arabic which describe Sheikh Ishaaq's travels, works and overall life in modern Somaliland, as well as his movements in Arabia before his arrival.Roland Anthony Oliver, J. D. Fage, Journal of African history, Volume 3 (Cambridge University Press.: 1962), p.45 Besides historical sources, one of the more recent printed biographies of Sheikh Ishaaq is the Amjaad of Sheikh Husseen bin Ahmed Darwiish al-Isaaqi as-Soomaali, which was printed in Aden in 1955.
Early migrations west
As the Isaaq grew in size and numbers during the 12th century, the clan-family migrated and spread from their core area in Mait (Maydh) and the wider Sanaag region in a southwestward expansion over a wide portion of present-day Somaliland by the 15th and 16th centuries. As the Isaaq expanded the earlier Dir communities of Mait and the wider Sanaag region were driven westwards and to the south towards their present positions. In this general expansion the Isaaq split up into their present component segments, however one fraction of the Habar Yunis clan, the Muse 'Arre, remains behind in Mait as the custodians of the tomb of Sheikh Ishaaq. By the 1300s the Isaaq clans united to defend their inhabited territories and resources during clan conflicts against migrating clans.
The Isaaq also played a prominent role in the Ethiopian-Adal War (1529–1543, referred to as the "Conquest of Abyssinia") in the army of Ahmad ibn Ibrahim al-Ghazi, The Habr Magadle division (Ayoub, Garhajis, Habr Awal and Arap) of the Isaaq were mentioned in chronicles of that war written by Shihab Al-Din Ahmad Al-Gizany known as Futuh al-Habasha. According to I.M Lewis The Marrehan and the Habr Magadle [Magādi] also play a very prominent role (...) The text refers to two Ahmads's with the nickname 'Left-handed'. One is regularly presented as 'Ahmad Guray, the Somali' (...) identified as Ahmad Guray Xuseyn, chief of the Habr Magadle. Another reference, however, appears to link the Habr Magadle with the Marrehan. The other Ahmad is simply referred to as 'Imam Ahmad' or simply the 'Imam'.This Ahmad is not qualified by the adjective Somali (...) The two Ahmad's have been conflated into one figure, the heroic Ahmed Guray (...)
After the war, the Isaaq clans (along with other tribes like the Daarood) grew in numbers and territory in the northeast, causing them to began to vie with their Oromo neighbours, who were expanding northwards themselves after the Great Oromo Migrations, thus creating a general thrust toward the southwest. The Isaaq, along with Darood subclans pushed westwards into the plains of Jigjiga and further, beyond where they played an important role in the Adal Sultanate's campaigns against Christian Abyssinia. By the 16th to 17th century the movements that followed seem to have established the Isaaqs on coastal Somaliland, while also having taken over much of Somaliland in that time period pushing the Oromo from the area.
Migrations southwards According to oral tradition, the Isaaqs, who were established in the coastal areas with a kingdom led by the Tol jeclo branch of the wider Isaaq family, began regularly fighting with the Darood tribes who lived to the south. The war was long and destructive, with both the Isaaqs and Daroods suffering heavy losses of life.
The Isaaq kingdom and the King Harun dhuh barar was eventually overthrown by a coalition of Isaaq clans led by a military leader named Abdi Eisa. According to tradition, Abdi Eisa successfully led the Isaaq forces in the Battle of Lafaruug, where they defeated the Absame tribes at the town of Lafaruug near Berbera— a region where the Isaaq clan had expanded about a century earlier.
Following his victory, Abdi Eisa was offered the position of Sultan of the Isaaq, but he declined. Instead, he suggested that his underage son, Guled Abdi, be crowned while he ruled as regent until his son came of age. The Isaaq gradually expanded their territory, reaching as far south as Toon and the edges of the Hawd by the beginning of the 19th century. The newly established Isaaq Sultanate subsequently made Toon its capital.
Migrations into the Hawd Throughout the 19th and early 20th centuries, the Isaaq clan expanded its presence in the Hawd region following a series of military victories against various neighboring clans.Proceedings of the Second International Congress of Somali Studies. Vol. II: Archaeology and History.pp291 Among these conflicts were the Rayyad Wars, led by Hersi Amman of the Habr Yunis and his successors, against the Dhulbahante and Ogaden tribes.
After the defeat of the Dervish movement in 1920, the Isaaq launched a series of raids and military campaigns against the Dhulbahante and Ogaden clans, who were left vulnerable. The Isaaq clans moved deep into the Ogaden region, where they were increasingly seen by the Ogaden clan as "sub-imperialists". The Isaaqs reached as far as the Hiiraan region in southern Somalia, the local complained saying “the invaders took everything and left nothing for us”. The intensity of these raids significantly weakened the resistance of the Dhulbahante and Ogaden, leading many to abandon their traditional grazing lands in the Hawd region. Others were forced to adopt a modus vivendi with the advancing Isaaq. The Isaaq expanse south was not limited to the Ogaden and Harti Darod, but also affected the Marehan who suffered from a series of devastating raids by the Habr Yunis.Index to the Correspondence of The Foreign Office for the Year 1923: Part 3Index to the Correspondence of The Foreign Office for the Year 1924: Part 4 These conflicts inspired the creation of a series of poetic exchanges between the Isaaq and Darod clans, known collectively as the Guba Poems. The historian Siegbert Uhlig, commenting on the significance of the Guba, highlights the historical narrative conveyed in the poetry of Ali Dhuh:
Uhlig notes that Ali Dhuh's poems describe the extensive territorial gains made by the Isaaq in traditionally Ogaden lands, the seizure of Ogaden wells, and the large-scale looting of their camels. The poems recount the dispersal of the Ogaden clan, their migration southward into fever-prone river valleys, and their adoption of farming and hunting—activities considered degrading and typically associated with slaves and lower-caste Somalis:
According to the poems, many Ogaden sought refuge among their Isaaq conquerors, particularly with the Habr Yunis. Ali Dhuh's verses depict the Ogaden as unable to retaliate, while the Isaaq are portrayed as flaunting their captured camels in front of their defeated adversaries. Uhlig remarks that even in translation, the poem remains highly evocative.Proceedings of the XVth International Conference of Ethiopian Studies Hamburg (2003), p. 215.
B. W. Andrzejewski author of A Somali Poetic Combat writes :During the period of administrative chaos which followed the war the Isaaq used their superior strength against both the Ogaadeen and the Dhulbahante. They looted many Ogaadeen herds, captured some of their wells and water-ponds, and dislodged them from a large part of their grazing areas in the Hawd. The Isaaq onslaught was so powerful that the Ogaadeen could put up little or no resistance, and did not even try to avenge their wrongs. Some of the clans, however, after being looted and pushed southward, developed a modus vivendi with the Isaaq and intermarried with them.A Somali Poetic Combat, B. W. Andrzejewski M.I Galaal. pp.15 In his book The Galla in Northern Somaliland Ioan Lewis states :The southwards expansion of the Somali from the shores of the Gulf of Aden still continues despite the establishment of international frontiers and Administrative control. It is very evident in the Northern Province of Kenya, and in the British Protectorate the Isaaq now appear to be pushing outside the territory at the expense of the Darod into the Ogaden and Haud.THE GALLA IN NORTHERN SOMALILAND, I.M Lewis pp.38
The Battle of Dheriyo was a pivotal and fiercely fought conflict between the Ciidagale and Ogaden clans, where the Ogaden forces reportedly suffered devastating losses, with only 15 survivors who surrendered in an attempt to save themselves, claiming to belong to the minority Sab (Madhiban) clan. The enraged Ciidagale warriors, emboldened by their thirst for vengeance from an earlier battle, reportedly took no prisoners. The battle was immortalized in Somali oral poetry, with poets like Qawdhan Ducaale and Cabdi Gahaydh vividly recounting the triumph of the Ciidagale and the humiliation of the Ogaden.
The Isaaq advance into Ogaden territory was eventually halted by the intervention of the British protectorate authorities with assistance from the Ethiopian Empire, who considered the Ogaden their subjects and whose safety was their priority. In one incident the Habar Yunis looted 1330 camels from the Ogaden, but were pressured by the British and the Ethiopians to return the camels to their previous owners. The Habr Yunis obliged and promised to desist in their raids, but despite their promise they continued to successfully raid the Ogadenis unhindered up until the British ceded the Haud to Ethiopia.The Mad Mullah of Somaliland, Douglas Jardine, p.197
