Ahmad ibn Fadlan ibn al-Abbas al-Baghdadi (Arabic: أحمد بن فضلان بن العباس بن راشد بن حماد, romanized: Aḥmad ibn Faḍlān ibn al-ʿAbbās al-Baghdādī) or simply known as Ibn Fadlan, was a 10th-century Arab traveler from Baghdad, Abbasid Caliphate, famous for his account of his travels as a member of an embassy of the Abbasid caliph al-Muqtadir to the king of the Volga Bulgars, known as his risāla ("account" or "journal"). His account is most notable for providing a detailed description of the Volga Vikings, including eyewitness accounts of life as part of a trade caravan and witnessing a ship burial. He also notably described the lifestyle of the Oghuz Turks while the Khazars, Cumans, and Pechenegs were still around.
