Mansur ad-Din of Adal

Mansur ad-Din (died 1424) was a Sultan of the Adal Sultanate. He was the son of Sa'ad ad-Din II.

Reign After his reconquest of Adal, Sabr ad-Din III died of natural causes in 1422. Sultan Mansur succeeded the throne and enjoyed the support of his brother Muhammad.

Early in his reign he launched an expedition against an Ethiopian Christian monarch, Emperor Dawit I and drove him to Yedaya which was described as his royal seat, destroyed the Solomonic army, where according to Maqrizi, Dawit was captured and killed. His death however presumed to be an event of major importance, is not recorded by the Ethiopian Chronicles. The Ethiopian historian Taddesse Tamrat argues it's because the Ethiopian royal chronicles often deliberately attempted to suppress the violent deaths of the kings whose reigns they extol.

Mansur later made his way towards to the Moha mountains where he surrounded a considerable imperial force of 30,000 soldiers. He besieged them for two months by the end of which they were suffering from hunger and thirst. He then offered them an ultimatum of embracing Islam or return to their homes. Some 10,000 men accepted the new faith of Islam; the remaining ones went home.

Death Soon after this the fortunes of war again changed. In 1424 another Christian monarch, Emperor Yeshaq I, set forth with a huge army which Maqrizi likens to a swarm of locusts. The christian troops were also trained by fugitive Mamluk who taught them the secrets of Greek fire. Mansur and his brother Muhammad were captured, and their brother Jamal ad-Din succeeded them on the throne immediately afterwards.
