This Unk-Khan was a real individual; he lost his life in the year 1203. Kuschhik, prince of the Nayman, and follower of Kor-Khan, fell in 1218.
Marco Polo, the Venetian traveller (1254-1324), identifies Unk-Khan with Prester John; he says, “I will now tell you of the deeds of the Tartars, how they gained the mastery, and spread over the whole earth. The Tartars dwelt between Georgia and Bargu, where there is a vast plain and level country, on which are neither cities nor forts, but capital pasturage and water. They had no chief of their own, but paid to Prester Johannes tribute. Of the greatness of this Prester Johannes, who was properly called Un-Khan, the whole world spake; the Tartars gave him one of every ten head of cattle. When Prester John noticed that they were increasing, he feared them, and planned how he could injure them. He determined therefore to scatter them, and he sent barons to do this. But the Tartars guessed what Prester John purposed ... and they went away into the wide wastes of the North, where they might be beyond his reach.” He then goes on to relate how Tschengis-(Jenghiz-)Khan became the head of the Tartars, and how he fought against Prester John, and, after a desperate fight, overcame and slew him.
The Syriac Chronicle of the Jacobite Primate, Gregory Bar-Hebræus (born 1226, died 1286), also identifies Unk-Khan with Prester John. “In the year of the Greeks 1514, of the Arabs 599 (A. D. 1202), when Unk-Khan, who is the Christian King John, ruled over a stock of the barbarian Hunns, called Kergt, Tschingys-Khan served him with great zeal. When John observed the superiority and serviceableness of the other, he envied him, and plotted to seize and murder him. But two sons of Unk-Khan, having heard this, told it to Tschingys; whereupon he and his comrades fled by night, and secreted themselves. Next morning Unk-Khan took possession of the Tartar tents, but found them empty. Then the party of Tschingys fell upon him, and they met by the spring called Balschunah, and the side of Tschingys won the day; and the followers of Unk-Khan were compelled to yield. They met again several times, till Unk-Khan was utterly discomfited, and was slain himself, and his wives, sons, and daughters carried into captivity. Yet we must consider that King John the Kergtajer was not cast down for nought; nay, rather, because he had turned his heart from the fear of Christ his Lord, who had exalted him, and had taken a wife of the Zinish nation, called Quarakhata. Because he forsook the religion of his ancestors and followed strange gods, therefore God took the government from him, and gave it to one better than he, and whose heart was right before God.”
Some of the early travellers, such as John de Plano Carpini and Marco Polo, in disabusing the popular mind of the belief in Prester John as a mighty Asiatic Christian monarch, unintentionally turned the popular faith in that individual into a new direction. They spoke of the black people of Abascia in Ethiopia, which, by the way, they called Middle India, as a great people subject to a Christian monarch.
Marco Polo says that the true monarch of Abyssinia is Christ; but that it is governed by six kings, three of whom are Christians and three Saracens, and that they are in league with the Soudan of Aden.
Bishop Jordanus, in his description of the world, accordingly sets down Abyssinia as the kingdom of Prester John; and such was the popular impression, which was confirmed by the appearance at intervals of ambassadors at European courts from the King of Abyssinia. The discovery of the Cape of Good Hope was due partly to a desire manifested in Portugal to open communications with this monarch,[22] and King John II. sent two men learned in Oriental languages through Egypt to the court of Abyssinia. The might and dominion of this prince, who had replaced the Tartar chief in the popular creed as Prester John, was of course greatly exaggerated, and was supposed to extend across Arabia and Asia to the wall of China. The spread of geographical knowledge has contracted the area of his dominions, and a critical acquaintance with history has exploded the myth which invested Unk-Khan, the nomad chief, with all the attributes of a demigod, uniting in one the utmost pretensions of a Pope and the proudest claims of a monarch.
