a second great Mongol empire, that of Kipchak in Russia; there was a third in Persia, that founded by Hulagu, the Ilkhan empire, to which the Seljuk Turks in Asia Minor were tributary; there was a Siberian state between Kipchak and Mongolia; and another separate state "Great Turkey" in Turkestan. It is particularly remarkable that India beyond the Punjab was never invaded by the Mongols during this period, and that an army under the Sultan of Egypt completely defeated Ketboga, Hulagu's general, in Palestine (1260), and stopped them from entering Africa. By 1260 the impulse of Mongol conquest had already passed its zenith. Thereafter the Mongol story is one of division and decay.

Now this story of Mongolian conquests is surely the most remarkable in all history. The conquests of Alexander the Great cannot compare with them in extent. And their effect in diffusing and broadening men's ideas, though such things are more difficult to estimate, is at least comparable to the spread of the Hellenic civilization which is associated with Alexander's adventure. For a time all Asia and Western Europe enjoyed an open intercourse; all the roads were temporarily open, and representatives of every nation appeared at the court of Karakorum. The barriers between Europe and Asia set up by the religious feud of Christianity and Islam were lowered. Great hopes were entertained by the papacy for the conversion of the Mongols to Christianity. Their only religion so far had been Shamanism, a primitive paganism. Envoys of the Pope, Buddhist priests from India, Parisian and Italian and Chinese artificers, Byzantine and Armenian merchants, mingled with Arab officials and Persian and Indian astronomers and mathematicians at the Mongol court. We hear too much in history of the campaigns and massacres of the Mongols, and not enough of their indubitable curiosity and zest for learning. Not perhaps as an originative people, but as transmitters of knowledge and method their in-
