The Tang Dynasty, with its capital at Chang'an (present-day Xi'an), the most populous city in the world at the time, is generally regarded as a high point in Chinese civilization - a golden age of cosmopolitan culture. Its territory, acquired through the military campaigns of its early rulers, was greater than that of the Han period, and it rivalled that of the later Yuan Dynasty, Ming Dynasty and Qing Dynasty. In 907 the Tang Dynasty was ended when Zhu Wen, now a military governor, deposed the last emperor of Tang, Emperor Ai of Tang, and took the throne for himself (known posthumously as Emperor Taizu of Later Liang).
