SINO-WESTERN CONTACTS

the former empire of Chingis Khan this development was, as we saw, mostly a result of the conversion of the ruling minority to the religion of the ruled majority. Events would have followed a different course if the Mongols had been able to substitute a religion, or a universal set of values of their own, for the existing indigenous creeds and patterns of life in their respective dominions; this had happened some centuries earlier with the Arabs who not only conquered much of the Near East but also succeeded in imposing Islam, their own religion, on the subjugated countries. In the cultural field, Islamisation had a much stronger effect on the affected areas and nations than the equally or even more far-reaching conquests of the Mongols in the thirteenth and fourteenth centuries. The most lasting, and, from the point of view of world history, perhaps most important result of East-West contacts in the period of Mongol domination was that these commercial and cultural contacts inaugurated for Europe the age of maritime exploration. The seafaring nations of Europe attempted to reach by sea those fabulous countries in the East which Marco Polo and other travellers or merchants had described after their travels through the Mongol dominions. When Columbus left Spain to discover a sea route to the East Indies and to Cathay, land of the Great Khan, he had a copy of Marco Polo's book on board his ship. And so it came that instead of achieving a renewed contact between the Far East and the West a new world was discovered.
