Qubilai Khan 忽必烈 (1215–1294), grandson of Činggis Khan, was the fifth Great Khan of the Mongol Empire and founding emperor (廟號 miàohào Shìzǔ 世祖, r. 1260–1294) of the Yuán 元 dynasty in China. His reign marked the consolidation of Mongol rule over China, the relocation of the capital to Dàdū 大都 (modern Beijing), and the integration of Tibetan Vajrayāna Buddhism — patronised through the imperial preceptors (帝師 dìshī) of the Sa-skya school, including ‘Phags-pa — into the imperial cult. The Yùzhì jiùdùfómǔ zàn 御製救度佛母讚 attributed to him survives as the prefatory imperial praise of the Tārā aṣṭottara-śata-stotra Chinese rendering by 安藏 Ān Zàng (KR6j0317, T20n1108A), an unprecedented imperial-Chinese endorsement of the Tibetan-Vajrayāna Tārā cult in canonical Buddhist literature.
