Lê Văn Duyệt
In 1824, My Duong, the eldest son of Prince Canh, was apparently accused of incest with his mother (Prince Canh's widow) by mandarin Lê Văn Duyệt, with the result that he was banished from the royal court, while his mother died in prison. My Duong was only rehabilitated in 1848 during the reign of Tự Đức, one year before his death.
