Nguyễn Nhạc
Tây Sơn dynasty was overthrown by Nguyễn Ánh in 1802. Nhạc's three sons, Nguyễn Thanh (阮清), Nguyễn Hân (阮昕) and Nguyễn Dũng (阮勇), were executed together with Nguyễn Quang Toản and other princes of Tây Sơn dynasty. The tombs of Nguyễn Nhạc and Nguyễn Huệ were razed to the ground, their remains were dug out and crushed into ashes. The skulls of Nguyễn Nhạc, Nguyễn Huệ and Huệ's wife, were locked up in prison in perpetuity. It was said that Nguyễn Huệ had desecrated the tombs of Nguyễn lords before, Nguyễn Ánh did that to "revenge for the ancestors" (爲九世而復讎).
