|Full name||Abu Al-fida' Isma'il Ibn 'ali|
|Died||732 AH (1331–1332)
Abu al-Fida (Arabic: أبو الفداء) or Abul Fida Ismail Hamvi (fully Abu Al-fida' Isma'il Ibn 'ali ibn Mahmud Al-malik Al-mu'ayyad 'imad Ad-din, (also transliterated Abulfeda, Abu Alfida, and other ways)) (November 1273 – October 27, 1331) was a Kurdish historian, geographer, and local sultan. The crater Abulfeda on the Moon, is named after him.
In his boyhood he devoted himself to the study of the Qur'an and the sciences, but from his twelfth year onward, he was almost constantly engaged in military expeditions, chiefly against the crusaders.
In 1285 he was present at the assault of a stronghold of the Knights of St. John, and took part in the sieges of Tripoli, Acre and Qal'at ar-Rum. In 1298 he entered the service of the Mamluk Sultan Malik al-Nasir and after twelve years was invested by him with the governorship of Hama. In 1312 he became prince with the title Malik us-Salhn, and in 1320 received the hereditary rank of sultan with the title Malik ul-Mu'ayyad.
For more than twenty years all together he reigned in tranquillity and splendour, devoting himself to the duties of government and to the composition of the works to which he is chiefly indebted for his fame. He was a munificent patron of men of letters, who came in large numbers to his court. He died in 1331.
