China: Zhao Ye Bai, a favourite horse of Emperor Xuanzong (712-56) by Hon Gong, Tang...

Emperor Xuanzong of Tang ( 8 September 685-3 May 762), also commonly known as Emperor Ming of Tang (Tang Minghuang), personal name Li Longji, known as Wu Longji, was the seventh emperor of the Tang dynasty in China, reigning from 712 to 756. His reign of 43 years was the longest during the Tang Dynasty. In the early half of his reign he was a diligent and astute ruler, ably assisted by capable chancellors like Yao Chong and Song Jing, and was credited with bringing Tang China to a pinnacle of culture and power. Emperor Xuanzong, however, was blamed for over-trusting Li Linfu, Yang Guozhong and An Lushan during his late reign, with Tang's golden age ending in the great Anshi Rebellion of An Lushan.
