The Embassy
Ibn Fadlan was sent from Baghdad in 921 to serve as the secretary to an ambassador from the Abbasid Caliph al-Muqtadir to the iltäbär (vassal-king under the Khazars) of the Volga Bulgaria, Almış.
The embassy's objective was to have the king of the Bolğars pay homage to Caliph al-Muqtadir and, in return, to give the king money to pay for the construction of a fortress. Although they reached Bolğar, the mission failed because they were unable to collect the money intended for the king. Annoyed at not receiving the promised sum, the king refused to switch from the Maliki rite to the Hanafi rite of Baghdad.
The embassy left Baghdad on June 21, 921 (Islamic Calendar: 11 Safar 309). It reached the Bulghars after much hardship on May 12, 922 (Islamic Calendar: 12 Muharram 310). (This day is an official religious holiday in modern Tatarstan.) The journey took Ibn Fadlan from Baghdad to Bukhara and Khwarizm (south of the Aral Sea). Although promised safe passage by the Oghuz warlord, or Kudarkin, they were waylaid by Oghuz bandits but luckily were able to bribe their attackers. They spent the winter in Gorgan, Iran before travelling north across the Ural River until they reached the towns of the Bulghars at the three lakes of the Volga north of the Samara bend.
After arriving in Bolğar, Ahmad ibn Fadlan made a trip to Wisu and recorded his observations of trade between the Volga Bolğars and local Finnic tribes.
