Emperor Huizong of Song
Chinese era names were titles adopted for the purpose of identifying and numbering years in Imperial China. Era names originated as mottos or slogans chosen by the reigning monarch and usually reflected the political, economic and/or social landscapes at the time. For instance, the first era name proclaimed by the Emperor Wu of Han, "Jianyuan" (; lit. "establishing the origin"), was reflective of its status as the first era name. Similarly, the era name "Jianzhongjingguo" (; lit. "establishing a moderate and peaceful country") used by the Emperor Huizong of Song was indicative of Huizong's idealism towards moderating the rivalry among the conservative and progressive parties regarding political and social reforms.
