With the sudden death of the Emperor Lê Thái Tông, his heir was an infant son named Bang Co. Two years later (1453) at the age of twelve, Lê Nhân Tông was formally given the title of Emperor. In 1459, Lê Nhân Tông's older brother, Nghi Dân, plotted with a group of friends to kill the Emperor. On October 28, the plotters with some 100 "shiftless men" entered into the palace and killed the Emperor (he was just 18).
