While Bayan was winning victories for his master and driving the Chinese armies from the field, Kublai was engaged at Pekin in the difficult and necessary task of consolidating his authority. In 1271 he gave his dynasty the name of Yuen or Original, and he took for himself the Chinese title of Chitsou, although it will never supersede his Mongol name of Kublai. Summoning to his court the most experienced Chinese ministers, and aided by many foreigners, he succeeded in founding a government which was imposing by reason of its many-sidedness as well as its inherent strength.
