In the Northern Sung dynasty the cult of Taoism began in the Ta-chung hsiang-fu 大中祥符 period (A.D. 1008-1016) and flourished during Emperor Hui-tsung's 徽宗 reign (A.D. 1101-1125). This is recorded in history. In fact, the background and scope of Taoist activities were not confined to the religious field, but ramified throughout the political sphere, in which struggles for personal power, factional strife, and intrigues between rival politicians and Taoist necromancers all played a complex part. Historians, however, did not explicitly tell us about these aspects which this article specifically studies. Part I deals with the building of Taoist monasteries, the bestowal of Taoist titles, the casting of the nine tripods, the printing of Taoist scriptures and the imparting of necromancy.
