King Bojang
Last king of Goguryeo, enthroned by Yeon Gaesomun, who surrendered in 668
A nephew of King Yeongnyu, he took the throne after Yeon Gaesomun’s coup in 642, but real power lay with Yeon as Grand Mangniji. In 643, on Yeon’s advice, he brought Daoist priests and the Daodejing from Tang to promote Daoism. Emperor Taizong’s invasion of 645 was halted at Ansi Fortress. Taken to Tang in 668, he returned in 677 as governor of Liaodong, but was exposed plotting with the Malgal to restore Goguryeo and died in exile.
