Imam Ahmad al-Ghazi

Imam Ahmad al-Ghazi (Arabic: Ahmad ibn Ibrahim al-Ghazi) was a military commander and leader from the Adal Sultanate, whose power was centered in the eastern Horn of Africa. He is also known by the epithet 'Guray' (left-handed), which appears in local tradition and in European historical sources as 'Gran' or 'Grañ'. He became renowned for leading military campaigns that took place in the sixteenth century in the lands of Abyssinia (the Christian Kingdom of Ethiopia).

His campaigns were part of the major conflicts between Adal and the Ethiopian state, which drew external intervention: the Portuguese, who supported Ethiopia, and the Ottomans, who provided weapons and soldiers to Adal. As a result, the conflict became part of the broader struggle for control of the Red Sea and Indian Ocean during that period.

Origins and rise to power

Ahmad came from the Adal Sultanate, a Muslim state whose territory stretched from eastern Ethiopia to the coasts of Somalia and Djibouti. Its political center was based in the city of Harar and its surrounding regions. Ahmad was not a sultan by birth; he rose to power through military service and clan and religious support, then took the title 'Imam', which combined both religious and military authority. His forces included Somali, Harari, Afar, and other local warriors, as well as foreign mercenaries.

Military campaigns

From the early sixteenth century onward, Ahmad led repeated attacks on the Christian kingdom's territories. His forces employed fast-moving cavalry and, crucially, firearms—cannons and muskets—obtained from the Ottomans, which transformed warfare in the region. For several years he controlled large portions of central and northern Ethiopia. The Ethiopian king sought aid from the Portuguese, who sent a military force equipped with firearms.

In his final battles, Ahmad was killed and his forces dispersed. His death led to the decline of Adal's power, and Ethiopia recovered much of the territory it had lost. Overall, the campaigns caused severe damage to both sides: widespread destruction, economic collapse, and population displacement that affected the subsequent migration of Oromo peoples.

Historical sources

The principal source on his campaigns is an Arabic text titled 'Futuh al-Habasha' (The Conquest of Abyssinia), written by a chronicler who accompanied Adal's forces. On the other side are Ge'ez chronicles from the Ethiopian court and Portuguese accounts written by diplomats and military officers who were present. Each source carries its own perspective, and historians must compare them carefully.
