Mongol Empire
The Mongol Empire, or Mongols, was a great empire during the 13th and 14th centuries. Beginning in the Central Asian steppes, it eventually stretched from Eastern Europe to the Sea of Japan, covered Siberia in the north and extended southward into Southeast Asia, the Indian subcontinent, and the Middle East.
War with the Assassins
During the 13th century, the Mongols were the major enemy of the Assassins. In 1227, the Assassin Grand Master Altaïr Ibn-La'Ahad, Darim Ibn-La'Ahad and Qulan Gal were responsible for the death of Genghis Khan, the founder of the Mongol Empire. Later in 1257, the Mongols besieged the Assassins' fortress of Masyaf, partially destroying and seizing it and causing the Assassin Order to be scattered throughout Europe, Africa and Asia.[1]
After the siege, the Mongols attacked the explorers Niccolò and Maffeo Polo and obtained the Assassins' Codex from them.[1] Years later, Niccolò's son Marco Polo retrieved the Codex from Kublai Khan.[2]
