Early history Adal (also
Awdal,
Adl, or
Adel) was situated east of the province of
Ifat and was a general term for a region of lowlands inhabited by Muslims. It was used ambiguously in the medieval era to indicate the Muslim inhabited low land portion east of the
Ethiopian Empire. Including north of the
Awash River towards
Lake Abbe as well as the territory between
Shewa and
Zeila on the coast of
Somaliland. According to Ewald Wagner, Adal region was historically the area stretching from Zeila to
Harar. In 1288, the region of Adal was conquered by the
Ifat Sultanate. Despite being incorporated into the Ifat Sultanate, Adal managed to maintain a source of independence under
Walashma rule, alongside the provinces of
Gidaya,
Dawaro, Sawans,
Bali, and
Fatagar. In 1332, Adal was invaded by the Ethiopian Emperor
Amda Seyon I. His soldiers were said to have ravaged the province. In the fourteenth century
Haqq ad-Din II transferred Ifat's capital to the
Harar plateau thus he is regarded by some to be the true founder of the Adal Sultanate. In the late 14th century, the Ethiopian Emperor
Dawit I collected a large army, branded the Muslims of the surrounding area "enemies of the Lord", and invaded Adal. After much war, Adal's troops were defeated in 1403 or 1410 (under Emperor
Dawit I or Emperor
Yeshaq I, respectively). According to al-Maqrizi, the
Walashma ruler
Sa'ad ad-Din II was captured and executed in Zeila, which he claims was sacked. His children and the remainder of the
Walashma dynasty would flee to
Yemen where they would live in exile until 1415. According to
Harari tradition numerous Argobba had fled Ifat and settled around Harar in the
Aw Abdal lowlands during their conflict with Abyssinia in the fifteenth century, a gate was thus named after them called the
gate of Argobba.
Rise of the Sultanate In 1415,
Sabr ad-Din III, the eldest son of
Sa'ad ad-Din II, would return to Adal from his exile in Arabia to restore his father's throne. He would proclaim himself "king of Adal" after his return from Yemen to the
Harar plateau and established his new capital at
Dakkar. Sabr ad-Din III and his brothers would defeat an army of 20,000 men led by an unnamed commander hoping to restore the "lost Amhara rule". The victorious king then returned to his capital, but gave the order to his many followers to continue and extend the war against the Christians. The Emperor of Ethiopia
Tewodros I was soon killed by the Adal Sultanate upon the return of Sa'ad ad-Din's heirs to the Horn of Africa. as well as the land further east all the way to Cape Guardafui, according to Leo Africanus. and his men. From
Le Livre des Merveilles, 15th century. Later on in the campaign, the Adalites were struck by a catastrophe when Sultan Mansur and his brother Muhammad were captured in battle by the Solomonids. Mansur was immediately succeeded by the youngest brother of the family
Jamal ad-Din II. Sultan Jamal reorganized the army into a formidable force and defeated the Solomonic armies at
Bale, Yedeya and Jazja. Emperor Yeshaq I responded by gathering a large army and invaded the cities of Yedeya and Jazja, but was repulsed by the soldiers of Jamal. Following this success, Jamal organized another successful attack against the Solomonic forces and inflicted heavy casualties in what was reportedly the largest Adalite army ever fielded. As a result, Yeshaq and his men fled to the
Blue Nile region over the next five months, while Jamal ad Din's forces pursued them and looted much gold on the way, although no engagement ensued. After returning home, Jamal sent his brother Ahmad with the Christian battle-expert Harb Jaush to successfully attack the province of Dawaro. Despite his losses, Emperor Yeshaq was still able to continue field armies against Jamal. Sultan Jamal continued to advance further into the Abyssinian heartland. However, Jamal on hearing of Yeshaq's plan to send several large armies to attack three different areas of Adal (including the capital), returned to Adal, where he fought the Solomonic forces at Harjai and, according to al-Maqrizi, this is where the Emperor Yeshaq died in battle. The young Sultan Jamal ad-Din II at the end of his reign had outperformed his brothers and forefathers in the war arena and became the most successful ruler of Adal to date. Within a few years, however, Jamal was assassinated by either disloyal friends or cousins around 1432 or 1433, and was succeeded by his brother
Badlay ibn Sa'ad ad-Din. Sultan Badlay continued the campaigns of his younger brother and began several successful expeditions against the Christian empire. He reconquered
Bali and began preparations of a major Adalite offensive into the
Ethiopian Highlands. He successfully collected funding from surrounding Muslim kingdoms as far away as the
Sultanate of Mogadishu. However, this ambitious campaign ended in disaster when Emperor
Zara Yaqob defeated Sultan Badlay at the
Battle of Gomit and pursued the retreating Adalites all the way to the
Awash River. Following the defeat and death of
Badlay ibn Sa'ad ad-Din at the
Battle of Gomit, the next Sultan of Adal,
Muhammad ibn Badlay, submitted to Emperor
Baeda Maryam I and started paying annual tribute to the
Ethiopian Empire with which he secure peace. Adal's
Emirs, who administered the provinces, interpreted the agreement as a betrayal of their independence and a retreat from the polity's long-standing policy of resistance to Abyssinian incursions. Emir Laday Usman of
Harar subsequently marched to
Dakkar and seized power in 1471. However, Usman did not dismiss the Sultan from office, but instead gave him a ceremonial position while retaining the real power for himself. Adal now came under the leadership of a powerful Emir who governed from the palace of a nominal Sultan. Usman would route emperor Baeda Maryam's troops in battle. Historian
Mohammed Hassen states the sultans of Adal had lost control of the state to Harar's aristocracy. armed with a musket and a cannon Emperor
Na'od and Sultan
Muhammad ibn Azhar ad-Din tried to remain at peace, but their efforts were nullified by the raids which Emir
Mahfuz constantly made into Christian territory.
Na'od who was determined to eliminate this threat, organized a large army and led it against the Emir, although the Emperor was victorious he was eventually killed in battle against the Adalites. Emperor
Dawit II (Lebna Dengel) would soon succeed the throne,
Mahfuz having recovered from his defeat renewed raids against the frontier provinces. He was stimulated by emissaries from Arabia who proclaimed the jihad (holy war), presented him with a green standard and brought in arms and trained men from Yemen. In 1516, Emir Mahfuz would then launch an invasion of
Fatagar, Lebna Dengel was prepared and organized a successful ambush, the Adalites were defeated and Mahfuz was killed in battle. Lebna Dengel then moved into Adal where he sacked the city of
Dakkar. Around the same time a Portuguese fleet surprised
Zeila whilst its garrison was away with Mahfuz, the Portuguese then burnt down the port city. After the victory of Lebna Dengel, the internal weaknesses of the Adal Sultanate soon revealed themselves. The older generation of the Muslims headed by the
Walashma, indifferent to religion and ready to come to terms with
Abyssinia, were staunchly opposed by the
Harari and
Harla religious aristocracy led by fanatic warlike emirs. The Sultan
Muhammad was assassinated in 1518 and Adal was torn apart by intestinal struggles in which five sultans succeeded each other in two years. But at last, a matured and powerful leader called
Garad Abun Adashe assumed power and brought order out of chaos. However, Sultan
Abu Bakr ibn Muhammad, who had transferred the capital from
Dakkar to
Harar in 1520, profiting off the prestige that the hereditary monarchy still held, recruited bands of Somali nomads, ambushed
Abun Adashe at Zeila and killed him in 1525.
Conquest of Abyssinia and
Ahmad Gragn's deaths. According to sixteenth century Adal writer
Arab Faqīh, in 1529 Imam
Ahmad ibn Ibrahim al-Ghazi finally decided to embark on a conquest of Abyssinia, he soon met the Abyssinians at the
Battle of Shimbra Kure where he would win a decisive victory. But his nomads where unreliable and difficult to control, to Ahmad's frustration some of his
Somali warriors would disperse back to their homelands after acquiring much plunder. At the same time, he faced opposition from his
Harari troops who dreaded the potential consequences of the Muslim base relocating to Abyssinia. He then returned to
Harar to reconstruct his forces and eliminate the tribal allegiances in his army, two years later he was able to organize a definite and permeant occupation of Abyssinia. From then the story of the conquest is a succession of victories, burnings and massacres. In 1531
Dawaro and
Shewa were occupied,
Bete Amhara and
Lasta in 1533. In 1535 Ahmad, in control of the east and center of Abyssinia invaded
Tigray where he encountered fierce resistance and suffered some reserves, but his advance was not stopped, his armies reached the coasts of
Medri Bahri where they made contact with Queen
Ga'ewa of Mazaga who joined their campaign against the
Ethiopian Empire. Emperor
Dawit II (Lebna Dengel) became a hunted fugitive, and harried from
Tigray to
Begemder to
Gojjam, constantly pursued by the Adalites. In this period Adal Sultanate occupied a territory stretching from
Zeila to
Massawa as well as the Abyssinian inlands. The Adalites were passionately interested in converting newly occupied territories. The impression given in the Muslim chronicles is that almost all of the Christian
Abyssinians had embraced Islam out of expediency. Among them was the governor of
Ifat who wrote to the Imam: However, in the integral regions of the
Ethiopian Empire, such as
Bete Amhara,
Tigray and
Shewa, the local population bitterly resisted the Adalite occupation. Some preferred death over denying their faith, among them were two
Amhara chiefs who were brought before the Imam in
Debre Berhan.
Arab Faqīh describes the encounter: In 1541 a small Portuguese contingent landed in
Massawa and soon all of Tigray declared for the monarchy, the Imam was defeated in several major engagements by the Portuguese and was forced to flee to
Raya Kobo with his heavily demoralized followers. He sent a request to the
Ottoman Empire for reinforcements of Turkish, Albanian and Arab musketeers to stabilize his troops. He then took the offensive attacking the Portuguese camp at Wolfa where he killed their commander,
Cristóvão da Gama, and 200 of their rank and file. The Imam then dismissed most of his foreign contingent and returned to his headquarters at
Lake Tana. The surviving Portuguese were able to meet up with
Gelawdewos and his army at the
Simien Mountains. The Emperor did not hesitate to take the offensive and won a major victory at the
Battle of Wayna Daga when the fate of Abyssinia was decided by the death of the Imam and the flight of his army. The invasion force collapsed like a house of cards and all the Abyssinians who had been cowed by the invaders returned to their former allegiance, the reconquest of Christian territories proceeded without encountering any effective opposition.
Collapse of the sultanate built by Emir
Nur ibn Mujahid In 1550
Nur ibn Mujahid became the Emir of Harar and the de facto ruler of Adal, he then began to strengthen the defenses of
Harar, building a wall that still encircles the city to this day. In 1559, urged on by his wife, Nur once again took the offensive and invaded the
Ethiopian Empire, killing Ethiopian Emperor
Gelawdewos in the
Battle of Fatagar. At the same time another Ethiopian army led by
Dejazmatch Hamalmal attacked Harar. Sultan
Barakat ibn Umar Din attempted to defend the city but was defeated and killed, thus ending the
Walashma dynasty. Not long after this, Barentu Oromos who had been migrating north invaded the Adal Sultanate. This struggle, which was mentioned by the monk
Bahrey, led to the devastation of many regions and Nur's army was defeated at the
Battle of Hazalo. The defensive walls managed to protect Harar from the invaders, preserving it as a kind of Muslim island in an Oromo sea. However, the city then experienced a severe famine as grain and salt prices rose to unpreceded levels. According to a contemporary source, the hunger became so bad that people began to resort to eating their own children and spouses. Nur himself died in 1567 of the pestilence which spread during the famine. Nur was succeeded by
Uthman the Abyssinian, who relaxed his predecessor's pro-Islamic policy and signed an infamous and humiliating peace treaty with the Oromos. The treaty stated that the Oromos can freely enter to the Muslim markets and purchase goods at less than the current market price. This angered many Muslims and led to a rebellion, in which he was overthrown and replaced by
Talha Abbas in 1569. Tahla would rule for only three years before being overthrown by some of his very fanatic subjects who were intent on another jihad or holy war against the Christians. He was replaced by Uthman's grandson
Muhammad ibn Nasir who soon carried out an expedition against the
Ethiopian Empire, however this campaign would end in total disaster. As soon as the army left Harar the Oromo ravaged the countryside, up to the walls of the city. Muhammad ibn Nasir was also defeated and killed at the
Battle of Webi River, thus permanently ending Adal aggression towards Ethiopia. Muhammad's successor,
Mansur ibn Muhammad, fought a fierce war against the Oromos, but was unable to defeat them. Mansur would also successfully reconquer
Aussa and
Zeila. The tension was all the greater after the death of Nur Ibn Mujahid, the disappearance of the last of the Walashma monarch also opened a tough competition for power between emirs and descendants of
Ahmed Ibn Ibrahim. Ultimately, they won in April 1576,
Muhammad Gasa took the title of
Imam, thus combining the political power of the Sultan and the religious responsibility of guiding the community, he then relocated the capital to the oasis of
Aussa in 1577, establishing the
Imamate of Aussa. The Imamate of Aussa declined gradually in the next century and was destroyed by the neighboring
Afar nomads who made
Aussa their capital. In the seventeenth century the induction of
Harla people and
Doba populations into Afar identity would lead to the emergence of
Aussa Sultanate.
Enrico Cerulli asserts that rulers of Zaila and Harar had effectively made themselves independent with the latter establishing the
Emirate of Harar. For two centuries, Adal Sultanate had claimed the role of spreading Islam in Ethiopia, but it now had to transition into an uncivilized state ruled by the Bedouin Dankalis, whom the Semitic or semiticized Adal aristocracy regarded merely as a group designated to plunder caravans. Scholar
Christopher Ehret noted that the majority of the inhabitants of the Adal Sultanate's primary territories were integrated into the Oromos, with the exception of small groups of Harari and Argobba speakers of Semitic languages. ==Demographics==
