The fifth emperor of the Qīng dynasty: temple-name Shìzōng 世宗, era-name Yōngzhèng 雍正. Personal name Aisin-Gioro Yìnzhēn 愛新覺羅·胤禛 (sometimes appearing in Buddhist canonical contexts as 胤禎 through scribal variation). Born 13 December 1678; died 8 October 1735, having ruled from 1722 (after succeeding his father Kāngxī 康熙).
His reign is foundational for the Qīng dynasty’s mature institutional consolidation:
- Bureaucratic centralization through the establishment of the Jūnjīchù 軍機處 (Council of State) in 1730, the principal organ of late-imperial Chinese decision-making until 1911.
- Fiscal reforms, including the famous tāndīngrùmǔ 攤丁入畝 reform (head-tax integration into land-tax) and the expansion of the huìpiào 會票 administrative-currency system.
- Tibetan Buddhist patronage consolidating the Manchu-Mongol-Tibetan religious-political settlement.
He was an unusually serious personal Chán Buddhist practitioner and student — among the most doctrinally engaged Chinese sovereigns of any dynasty. His Buddhist literary output is correspondingly substantial:
- Yùxuǎn yǔlù 御選語錄 (KR6s0069, X1319, 19 juan, 1733) — an imperially-edited selection of Chán yǔlù.
- Yùzhì jiǎnmó biànyì lù 御製揀魔辨異錄 (KR6s0068, X1281, 8 juan) — polemical refutation of Hànyuè Fǎzàng 漢月法藏 (1573–1635) in defense of the orthodox Mìyún Yuánwù 密雲圓悟 (KR6q0604) line of LínjìYángqí Chán.
- Yùlù Zōngjìng dàgāng 御錄宗鏡大綱 (KR6s0070, L1668, 20 juan) — imperially-compiled abridgment of Yǒngmíng Yánshòu’s 永明延壽 (904–975) hundred-juan Zōngjìnglù 宗鏡錄 (T2016).
He also commissioned the imperially-edited recension of the Míng Jiàoshèng fǎshù — the Chóngdìng jiàoshèng fǎshù 重訂教乘法數 (KR6s0009, L1666) — completed in 1735 and bearing his August 1735 imperial preface.
His Buddhist programmatic positioning was systematic: privileging the Mìyún Yuánwù line of LínjìYángqí Chán as the orthodox Chán transmission, suppressing the Hànyuè Fǎzàng deviation, integrating Chán practice with Pure Land and Esoteric lineages under the unified imperial canopy, and eventually inaugurating the major canonical-printing project that became the Qiánlóng Lóngzàng 龍藏 canon (begun 1735, completed 1738 under his successor Qiánlóng).
He died on the 23rd day of the 8th month of Yōngzhèng 13 = 8 October 1735, succeeded by his son the Qiánlóng emperor 乾隆帝 (Hong-li 弘曆, r. 1735–1796).
