Upon his death in 1883, the childless Tự Đức had named his nephew, Kiến Phúc, as his successor, rather than Dục Đức, his most senior heir. Tự Đức had written in his will that Dục Đức was depraved and unworthy of ruling the country. However, led by Thuyet, the regents enthroned Dục Đức under the pressure of the ladies of the court. Phan protested against the violation of Tự Đức's will of succession and refused to sanction anyone other than Kien Phuc. Lucky to escape the death penalty, Phan was stripped of his positions. Later, Dục Đức was deposed and executed by Thuyet on the grounds of ignoring court etiquette, ignoring the mourning rites for Tự Đức and having affairs with the late emperor's consorts. Phan again protested the regents' actions and was briefly imprisoned by Thuyet, before being exiled to his home province.
