which instead was wracked by a succession struggle between Yeon's sons. Fall of Goguryeo and after As internal struggles continued in Goguryeo, Yeon Namsaeng defected and 40 castles near the border surrendered to the Tang, while Yeon Jeong-to, Yeon Gaesomun's brother, defected to Silla. The Goguryeo capital fell to Silla-Tang forces in the ninth lunar month of 668, and King Bojang was captured. He was appointed to the minister of public works (工部尚書) by Tang Gaozong. Tang faced increasing problems ruling the former inhabitants of Goguryeo, as well as Silla's resistance to Tang's remaining presence on the Korean Peninsula. In 677, the Tang insisted on crowning Bojang as the "King of Joseon" and put him in charge of the Liaodong Commandery (Hangul : 요동주도독 조선왕 Hanja:遼東州都督朝鮮王) of the Protectorate General to Pacify the East. However, Bojang continued to foment rebellions against Tang in an attempt to revive Goguryeo, organizing Goguryeo refugees and allying with the Malgal tribes. He was eventually banished to Sichuan in 681, and died the following year. Because Bojang was the last ruler of Goguryeo, he did not receive a temple name after his death. There was a brief attempt at Goguryeo restoration made by Anseung, who ultimately surrendered to Silla.
