Lü Guang
The Former Qin ruler Fu Jian was a strong patron of Buddhist scholarship. After capturing Xiangyang in 379, he invited the monk Dao An to Chang'an to catalogue Buddhist scriptures. When the teachings of the famed Kuchean monk, Kumārajīva, reached Chang'an, Dao An advised Fu Jian to invite the Kumārajīva. In 382, Fu Jian sent general Lü Guang to conquer the Western Regions (Tarim Basin) and bring Kumārajīva to Chang'an. Lü Guang captured Kucha and seized Kumārajīva, but the Former Qin kingdom collapsed after the Battle of Feishui in 383. Lü Guang founded the Later Liang and held Kumārajīva captive in western Gansu for 18 years. In 401, the Later Qin ruler, Yao Xing conquered the Former Liang and Kumārajīva was able to settle in Chang'an and become one of the most influential translators of Buddhist sutras into Chinese.
