Xuanzong

 or Hsüan-tsung orig. Li Longji

(born 685, Louyang, China—died April 762, Chang'an) Sixth emperor (r. 712–756) of the Tang dynasty of China, which during his reign achieved its greatest prosperity and cultural brilliance. Xuanzong reformed the bureaucracy, increased tax revenues through reregistering the population, improved the transportation system, and established a permanent military force along China's northern frontiers. Toward the end of his reign, he withdrew increasingly from government and came under the influence of his consorts, including the notorious beauty Yang Guifei. The An Lushan Rebellion of 755–756 forced him to flee the capital, Chang'an (modern Xi'an), and he abdicated in favour of the heir apparent.
