Lê Tuong Duc (1510 - 1516). Lê Tu9o9ng Duc proved to be just as bad a ruler as Lê Uy Muc. He reigned from 1510 to 1516, all the while spending down the royal treasury, and doing nothing to improve the country. He was heedless to the reaction that his taxes caused throughout the country. His rule ended in 1516 when a group of officials and generals stormed the palace and killed him.
