Manchu began as a primary language of the Qing dynasty Imperial court, but as Manchu officials became increasingly sinicized, many started losing the language. Trying to preserve the Manchu identity, the imperial government instituted Manchu language classes and examinations for the bannermen, offering rewards to those who excelled in the language. Chinese classics and fiction were translated into Manchu, and a body of Manchu literature accumulated. As the Yongzheng Emperor (reigned 1722–1735) explained, "If some special encouragement … is not offered, the ancestral language will not be passed on and learned." Still, the use of the language among the bannermen declined throughout the 1700s. Historical records report that as early as 1776, the Qianlong Emperor was shocked to see a high Manchu official, Guo'ermin, not understand what the emperor was telling him in Manchu, despite coming from the Manchu stronghold of Shengjing (now Shenyang). By the 19th century even the imperial court had lost fluency in the language. The Jiaqing Emperor (reigned 1796–1820) complained that his officials were not proficient at understanding or writing Manchu.
