Táng Xiànzōng 唐憲宗 (personal name Lǐ Chún 李純, 778–820 CE), eleventh emperor of the Táng dynasty, reigned 805–820 (Yuánhé 元和 era 806–820). Best known politically for the partial restoration of central authority after the An-Lushan rebellion through campaigns against the autonomous border provinces (藩鎮). For Buddhist cultural history he is associated with the imperially commissioned Cháng’ān translation projects of the Yuánhé era, including the translation of [[KR6b0008|Dàshèng běnshēng xīndìguān jīng 大乘本生心地觀經 (T159)]] by 般若 Prajña in 810–811. Famously, Xiànzōng’s reception of the Buddha-relic in 819 occasioned 韓愈 Hán Yù’s anti-Buddhist memorial Lùn fógǔ biǎo 論佛骨表.
