In the winter of 642, King Yeongnyu was apprehensive about Yeon Gaesomun and plotted with his other officials to kill him. When Yeon Gaesomun discovered the plot, he arranged a lavish banquet to celebrate his rise to the position of Eastern Governor () to which one hundred of the opposing politicians of the nation were invited. Yeon Gaesomun ambushed and killed all one hundred politicians present, and then proceeded to the palace and murdered King Yeongnyu. According to traditional Chinese and Korean sources, Yeon Gaesomun's men dismembered the king's corpse and discarded it without proper ceremony.
