This study will lead us to rethink the characteristics of the political hegemony which was established by Qubilai who was the Qaγan of the Yeke Mong γol Ulus(Great Mongol Empire). It has been broadly affirmed that the Great Mongol Empire which was founded by ?inggis Qan made the big territorial expansion which was an action beyond example in world history. But the study of the Mongol Empire published till now made a great mistake in the part concerning Qubilai Qaγan who was ?inggis Qan 's grandson. It has been insisted that barbaric nomadic peoples, Mongol, could not but sinificate after they had contacted with the high civilization of China. Qubilai Qaγan was the typical example of the sinification. It has been insisted too that the Mongol Empire lost their total ruling power, was divided into three self-governing dominions, H ?leg? ulus, Jo?i ulus, ?ayatai ulus and one direct-governing dominion Y?an Dynasty, which it controlled China only after Qubilai Qaγan had founded Yuan Dynasty (元朝)in 1271. But these studies failed us to have a total grasp of the political hegemony of Qubilai Qaγan. First, let us examine the human, material back-ups of Qubilai Qaγan 's regime. The previous studies only accented Chinese who served Qaγan’s regime, emphasized the economic power of Chinese domain. But Qubilai Qaγan himself thought it as the means of the permanent development of The Mongol Empire. Second, let us see whether Qubilai's accession to the throne of China caused the total Mongol Empire to dissolve. But I found individual uluses to approve Qubilai's assumption of political hegemony, endorse his accession to the ruler of The Mongol Ernpire- Qaγan, Last, Qubilai's dwelling place was studied. Qubilai never dwelt in the T'a-tu (大都), the capital of The Mongol Empire because he was a nomad innately, he lived a nomadic living (Ordo 行宮), looking for the good pasrures near the T' a-tu and the Shang-tu(上都) in his reign. T' a-tu was designed for Chinese, not for Qubilai himself and the Mongol. And Qubilai only constructed the city as the symbol of The Mongol Empire's rule over the world. Although Chinese regarded Qubilai as 'Son of Heaven' of China, Qubilai thought himself as Qaγan of the Mongol Empire in which it had world-wide territories, as well as 'Son of Heaven' of China, conducted himself world-widely. In conclusion, Qubilai conquered China for the revival of The Mongol Empire. He never gained, ruled China at the cost of Empire.
