Abà « al-ýAbbÃÂs Aḥmad ibn Muḥammad ibn ýIá¸ÂÃÂrë al-MarrÃÂkushë () was a Maghrebi historian of the late-13th/early-14th century, and author of the famous Al-Bayan al-Mughrib, an important medieval history of the Maghreb and Al-Andalus (now the Iberian Peninsula) written in 1312.
Ibn IdhÃÂri was born and lived in Marrakesh (present-day Morocco), and was a qÃÂþid ('commander') of Fez. Little is known of his life. His only surviving work, Al-Bayan al-Mughrib, is a history of North Africa from the conquest of Miá¹£r in 640/1 AD to the Almohad conquests in 1205/6 AD. Its value to modern scholarship lies in its extracts from older works, now lost, and in its material not found elsewhere, including reports of the first Viking raids on Al-Andalus in the ninth century. He mentions another biographic work on the caliphs, imÃÂms and amërs from across the Islamic world, which has not survived. He died after 1312 / 712 AH.
