Niccolò Polo (c. 1230 – c. 1294) was a Venetian merchant and explorer, and the father of the famed explorer Marco Polo. Working with his brother Maffeo for the majority of his life, they established trading posts in Constantinople, Sudak and in a western part of the Mongol Empire. In 1257, Niccolò and Maffeo were inducted into the Assassin Order by the Mentor of the Levantine Brotherhood, Altaïr Ibn-La'Ahad, and his son Darim. Entrusted with Altaïr's Codex and the future of the Assassin Order, the Polo brothers established various Assassins Guilds, like in Constantinople and Venice.
