of China's golden ages. The series reveals (fictionally) a reason for Princess Wencheng's famed political marriage to Songtsen Gampo of the Tibetan Empire. Princess Wencheng was probably not an imperial princess but a niece or maid of Emperor Taizong's or the Imperial Household's, who was married to Songtsen Gampo, forging an alliance between the Tang Empire and the Tibetan Empire. Princess Wencheng would later help to develop technology and more civilised and idealistic standards of living in Tuoba, which was then regarded by the Chinese as an almost barbaric empire. The series mentions (and probably exaggerates) gender equality during the Tang Dynasty. The Tang Dynasty was in fact a period of a Chinese history in which women were fairly liberated, with records of outspoken courtesans and women of prominent families playing the Persian sport of polo with gentry men. The first instance of feminism in the Tang Dynasty was established very early on, when the daughter of the Tang's founding father Emperor Gaozu, Princess Pingyang, made large military contributions and in fact led military forces to help overthrow the Sui and establish the Tang. Emperor Taizong was the first husband of the young Wu Zetian, who would later become a favourite of Emperor Gaozong's, then his Empress consort, a regent power and eventually an Empress regnant in her own right, interrupting the Tang Dynasty's early stages with the Later Zhou. Wu Zetian would rule as the only historically recorded female imperial monarch of Chinese history, and she would even further contribute to gender equality in the Tang after Princess Pingyang. Her efforts would include the installing Shangguan Wan'er as a political and literary scholar. The series references trade with foreign empires. China at the time was by far the world's largest economy, and many foreign empires and states paid homage to China and traded with China. Trade with the West flourished for China under the Tang. China also imported aspects of foreign culture. Chang'an, the Tang capital, was a cosmopolitan area boasting a huge population. Christianity reached China for the first time around the time setting of the series. Buddhism was imported during the Northern and Southern Dynasties from India and its presence was solidified under the Tang. Chinese hanfu also made major alterations, adopting some of the court styles of the Persian Empire. Sports, philosophies and consumer goods were all imported, as well as exported. Lead cast Note: Some
