|McCune–Reischauer||Kŏnmu / Sŏng|
In China, the Sui Dynasty was followed by the Tang Dynasty in 618, the year of Yeongnyu's ascension. Goguryeo was recovering from the Goguryeo-Sui War, and the new Tang emperor was still completing its internal unification. Neither being in a position for new hostilities, Goguryeo and Tang exchanged emissaries and upon Tang's request, conducted a prisoner exchange in 622.
However, as Tang gained strength, in 631, it sent a small force to destroy a monument to Goguryeo's victory over the Sui. In response, Goguryeo built the Cheolli Jangseong defensive wall along the western border, a 15-year project begun in 631 under the supervision of Yeon Gaesomun.
Fall, death and successionEdit
Yeongnyu and some of the government officials planned to kill some of the more powerful military officers. They planned first to kill Yeon Gaesomun, whose power and influence were rapidly overtaking the throne's. The young man eventually discovered the plot, and immediately went to Pyongyang to kill the plotters, including the king. Yeongnyu was killed in 642.
