The Adal Sultanate was a medieval Sunni Muslim state of the Horn of Africa, founded by Sabr ad-Din III on the Harar plateau after the collapse of the Sultanate of Ifat. At its height under Sultan Badlay it controlled territory from Cape Guardafui in Somalia to Suakin in Sudan, spanning parts of today's Ethiopia, Djibouti, Somalia and Somaliland.

Overview

History

Adal's ruling Walashma dynasty had fled to Yemen after the Ethiopian emperor Dawit I defeated and executed Sultan Sa'ad ad-Din II around 1403–1410. In 1415 Sabr ad-Din III returned, proclaimed himself "King of Adal" and defeated an Ethiopian army, inaugurating a century of intermittent war with the Christian Solomonic Empire. His brothers Mansur ad-Din and Jamal ad-Din II campaigned deep into Abyssinia—Mansur killed Emperor Dawit I, and Jamal's victories at Bale, Yedeya and Jazja made him the most successful early sultan. Sultan Badlay ("the Monster") extended Adal's power over the entire northern seaboard but was defeated and killed by Emperor Zara Yaqob at the Battle of Gomit in 1445. Thereafter the sultans grew weak: from 1471 real power passed to the emirs of Harar, notably Mahfuz, whose frontier raids provoked Ethiopian invasions and the sacking of Dakkar in 1516.

The sultanate's apogee came under Imam Ahmad ibn Ibrahim al-Ghazi ("Ahmad Gran"), who seized power in the 1520s and from 1529 launched the Conquest of Abyssinia. Winning decisively at Shimbra Kure, his armies—Somali, Afar, Harari and Harla troops stiffened by the elite Malassay and Ottoman musketeers—overran most of highland Ethiopia by 1535, forcing Emperor Lebna Dengel into flight. Portuguese intervention under Cristóvão da Gama and the Ethiopian rally under Gelawdewos turned the tide: Ahmad was killed at the Battle of Wayna Daga in 1543 and the conquest collapsed. Emir Nur ibn Mujahid rebuilt Harar's famous walls and killed Gelawdewos at Fatagar in 1559, but the Walashma line ended the same year and massive Oromo migrations devastated the state. In 1577 Imam Muhammad Gasa moved the capital to Aussa, where the successor Imamate of Aussa slowly declined before Afar nomads.

Decline and legacy

Adal's wealth came from Indian Ocean trade through Zeila and Berbera—gold, ivory, slaves, cattle, millet and khat—in exchange for Chinese celadon, glassware and textiles; it used imported Egyptian dinars and dirhems. Its people were Somalis, Afars, Hararis, Argobba and Harla; Arabic was the lingua franca of a Shafi'i-Ash'ari Sunni state with strong Sufi (Ba 'Alawiyya, Shadhili) traditions. Its legacy lives on in the walled city of Harar (a UNESCO site), the Awdal region's name, and the ruined stone cities of Somaliland such as Amud and Abasa.
