The first part of the film and book closely follows ibn Fadlan’s actual journal—including his exile from Baghdad and his initial encounter with the Northmen.

Il 13° Guerriero (The 13th Warrior) is a unique blend of historical fact and legendary fiction. Its story is built on two primary foundations: the real-world travels of a 10th-century Arab diplomat and the epic Anglo-Saxon poem Beowulf . The Real History: Ahmad ibn Fadlan

The film’s protagonist, Ahmad ibn Fadlan (played by Antonio Banderas), was a real 10th-century legal scholar and diplomat from Baghdad. In AD 921, he was sent by the Abbasid Caliph to visit the king of the Volga Bulgars in what is now modern-day Russia.
