Ethiopian–Adal War
The Ethiopian–Adal War or Abyssinian-Adal War, also known in Arabic as the Futuḥ al-Ḥabash ( "Conquest of Abyssinia"), was a military conflict between the Christian Ethiopian Empire and the Muslim Adal Sultanate from 1529 to 1543. Ethiopian troops consisted of Amharas, Tigrayans, and Agaw people, while Adal forces were made up of the Somali, Harari, Afar, Argobba, Hadiya, and now extinct Harla ethnic groups, along with Turkish and Arab gunmen, with both sides making use of ethnic Maya mercenaries. Background. Adal's history from this founding period forth would be characterized by a succession of  battles with neighbouring Abyssinia. Ahmed fighters were using bows and arrows. Imam Ahmad ibn Ibrahim al-Ghazi was a military leader of the medieval Adal Sultanate in the northern Horn of Africa. Between 1529 and 1543, he defeated several Ethiopian emperors and embarked on a conquest referred to as the "Futuh Al-Habash" ("Conquest of Abyssinia"), which brought three-quarters of Christian Abyssinia under the power of the Muslim Sultanate of Adal. With an army which composed of Afar, Harari, and Somalis.Al-Ghazi's forces and their Ottoman allies came close to extinguishing the ancient Ethiopian kingdom. However, the  Abyssinians managed to secure the assistance of Cristóvão da Gama's Portuguese troops and maintain their domain's autonomy. Both polities in the process exhausted their resources and manpower, which resulted in the contraction of both powers and changed regional dynamics for centuries to come. Many historians trace the origins of hostile Ethiopia–Somalia relations to this war. Some scholars also argue that this conflict proved, through their use on both sides, the value of firearms such as the matchlock musket, cannons, and the arquebus over traditional weapons. Course of the war. In 1529, Imam Ahmad's Adal troops defeated  a larger Ethiopian contingent at the Battle of Shimbra Kure. The victory came at a heavy cost but it solidified the Adal forces' morale, providing proof that they could stand up to the sizable Ethiopian army. The victories that gave the followers of Imam Ahmad the upper hand came in 1531. The first was at Antukyah, where cannon fire at the start of the battle panicked the Ethiopian soldiers. The second was on 28 October at Amba Sel, when troops under the Imam not only defeated but dispersed the Ethiopian army and captured items of the Imperial regalia. These victories  allowed the Adalites to enter the Ethiopian highlands, where they began to sack and burn numerous churches, including Atronsa Maryam, where the remains of several Emperors had been interred. Dawit II died in 1540 and his son Menas and the future emperor was captured by the forces of Imam Ahmad; the Empress was unable to react as she was besieged in the capital. In 1543, a smaller number of Abyssinians soundly defeated the larger Adal-Ottoman army with the help of the Portuguese navy, which brought 400 musketeers led by Cristóvão da Gama via Massawa, a port in the Eritrean  Kingdom of Medri Bahri, an important port today in present-day Eritrea. However, Da Gama was captured in the battle of Battle of Wofla and later killed. The 500 musketeers were led by Bahri Negassi Yeshaq, king of Medri Bahri. Yeshaq not only provided the Portuguese with provisions and places to camp in his realm but also information about the land. The Bahr negus also joined Emperor Gelawdewos and the Portuguese in the decisive Battle of Wayna Daga, where tradition states that Ahmad was fatally wounded by a Portuguese musketeer, named João the Gallician, who had charged alone into the  Muslim lines and died avenging his commander Cristóvão da Gama. Once the Imam's soldiers learned of his death, they fled the battlefield. The death of Imam Ahmed and the victory in the Battle of Wayna Daga caused a collapse of Ahmed forces and forced an Adalite retreat from Ethiopia. Aftermath. Emir Nur ibn Mujahid succeeded his uncle Ahmad ibn Ibrahim al-Ghazi as leader of the Adal forces and consolidated his power by marrying Bati del Wambara. Mohammed Hassan has plausibly argued that because this conflict severely weakened both participants, it provided an opportunity for the Oromo people to  migrate into the historically Gafat land of Welega south of the Blue Nile and eastward to the walls of Harar, establishing new territories. In 1559, Emir Nur's cavalry defeated and killed Emperor Gelawdewos in battle, and sacked the Abyssinian town of Waj. Simultaneously, Abyssinian General Ras Hamalmal sacked Harar and captured sultan Barakat ibn Umar Din, and killed him. J. Spencer Trimingham postulates that the captured Barakat ibn Umar Din was in fact returned to Adal in exchange for Prince Menas in negotiations led by Bati del Wambara. Emir Nur ibn Mujahid, returning from his campaign, would display the  head of Emperor Gelawdewos in Harar as a show of triumph. In 1577, Emperor Sarsa Dengel defeated and executed Sultan Muhammad V in Bale. He was succeeded by Imam Muhammad Jasa, a relative of Ahmad ibn Ibrahim al-Ghazi, who relocated Adal's capital to Aussa. while Susenyos I relocated the capital of Abyssinia to Gondar.
