The Complete History (Arabic: الكامل في التاريخ, al-Kāmil fit-Tārīkh), is a classic Islamic history book written by Ali ibn al-Athir. Composed in ca. 1231AD/628AH, it is one of the most important Islamic historical works. Ibn al-Athir was a contemporary and member of the retinue of Saladin, the Sultan of Egypt who captured Jerusalem from the Crusaders and massively reduced European holdings in the Levant, leaving the Principality of Antioch and County of Tripoli much reduced and only a few cities on the coast to the Kingdom of Jerusalem.
