Marco Polo was a Venetian merchant who traveled extensively in Asia. Along with his father Niccolò and his uncle Maffeo, in 1271, Marco left for a diplomatic mission which led them to Kublai Khan's Mongol court.
Kublai Khan's acceptance of the Polo family gave them unprecedented access to his empire. Khan appointed Marco as a special envoy, which allowed the young man to enter places never before explored by Europeans. In 1275, Marco was able to retrieve the lost Codex of Altaïr Ibn-La'Ahad, which was located in the Mongol summer capital of Shangdu. Marco Polo brought the Codex back to Venice and became the patron of a member of the Assassin Brotherhood.
