Lǐ Línfǔ, a distant cousin of the Tang imperial house (descended from Lǐ Shūliáng 李叔良, brother of Tang Gāozǔ 高祖), was Director of the Secretariat (中書令) under Xuánzōng 玄宗 from Kāiyuán 22 (734) until his death in Tiānbǎo 11 (752). His nineteen-year ascendancy is conventionally treated by Tang historians as the turning point at which the early Kāiyuán “good government” gave way to the conditions that produced the An Lùshān rebellion: he was credited with consolidating power in the Secretariat at the expense of the Department of State Affairs, sidelining literati ministers (notably his rival 張九齡), and promoting non-Han military commanders such as An Lùshān 安祿山 to the regional commands. The commentary to Táng liùdiǎn 唐六典 (KR2l0001) is conventionally credited to him “by imperial command,” though it was in fact the work of the editorial team under his nominal supervision. Posthumously stripped of titles after his death when his role in the destruction of the heir-apparent and other intrigues came to light. Biographies in Jiù Tángshū 106 and Xīn Tángshū 223. Birth year not securely known; death 752 confirmed in CBDB.
