he 9th or 10th centuries. According to I.M. Lewis, the polity was governed by local dynasties consisting of Somalized Arabs or Arabized Somalis, who also ruled over the similarly-established Sultanate of Mogadishu in the Benadir region to the south. Adal's history from this founding period forth would be characterized by a succession of battles with neighbouring Abyssinia. At its height, the Adal kingdom controlled large parts of modern-day Somalia, Ethiopia, Djibouti and Eritrea.
In 1332, the Zeila-based King of Adal was slain in a military campaign aimed at halting the Abyssinian Emperor Amda Seyon's march toward the city. When the last Sultan of Ifat, Sa'ad ad-Din II, was also killed by Emperor Dawit I in Zeila in 1410, his children escaped to Yemen, before later returning in 1415. In the early 15th century, Adal's capital was moved further inland to the town of Dakkar, where Sabr ad-Din II, the eldest son of Sa'ad ad-Din II, established a new base after his return from Yemen.
Adal's headquarters were again relocated the following century, this time to Harar. From this new capital, Adal organised an effective army led by Imam Ahmad ibn Ibrihim al-Ghazi (Ahmad "Gurey" or "Gran") that invaded the Abyssinian empire. This 16th century campaign is historically known as the Conquest of Abyssinia (Futuh al-Habash). During the war, Imam Ahmad pioneered the use of cannons supplied by the Ottoman Empire, which he imported through Zeila and deployed against Abyssinian forces and their Portuguese allies led by Cristóvão da Gama. Some scholars argue that this conflict proved, through their use on both sides, the value of firearms like the matchlock musket, cannons and the arquebus over traditional weapons.
During the Ajuuraan period, the sultanates and republics of Merca, Mogadishu, Barawa, Hobyo and their respective ports flourished and had a lucrative foreign commerce, with ships sailing to and coming from Arabia, India, Venetia, Persia,
