Emperor Shenzong of Song
In 1066, he presented a more detailed eight-volume "Tongzhi" (通志; "Comprehensive Records"), which chronicled Chinese history from 403 BCE to 207 BCE (the end of the Qin Dynasty). The emperor issued an edict for the compilation of a groundbreaking universal history of China, granting full access to imperial libraries, and allocating funds for the costs of compilation, including research assistance by experienced historians such as Liu Ban (劉攽, 1022–88), Liu Shu (劉恕, 1032-78), and Fan Zuyu (范祖禹, 1041–98). After Yingzong died in 1067, Sima was invited to the palace to introduce his work-in-progress to Emperor Shenzong of Song. The new emperor not only confirmed the interest his father had shown, but showed his favor by bestowing an imperial preface in which he changed the title from "Tongzhi" ("Comprehensive Records") to "Zizhi Tongjian" ("Comprehensive Mirror to Aid in Government"). Scholars interpret the "Mirror" of the title to denote a work of reference and guidance, indicating that Shenzong accepted Sima as his guide in the study of history and its application to government. The emperor maintained his support for the compilation of this comprehensive history until its completion in 1084.
