Bojang of Goguryeo - Fall of Goguryeo

Fall of Goguryeo

As internal struggles continued in Goguryeo, Yeon Namsaeng defected and 40 castles near the border surrendered to the Tang, while Yeon Jeong-to 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, Tang crowned Bojang "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, King 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 Szechuan 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.

King Bojang of Goguryeo, was also the last of King Dongmyeong of Goguryeo (Jumong was the founding Monarch of Goguryeo) ancestors to rule Goguryeo.
