Ton That Dinh (mandarin)

Tôn Thất Đính (尊室訂, ?–1885) was a mandarin of the Nguyễn Dynasty who served under Emperor Tự Đức. He was the governor of Hải Dương Province. His son Tôn Thất Thuyết went on to become a high-ranking mandarin, who became the regent upon the death of Tự Đức.

After Thuyết launched the Can Vuong movement that attempted to install the boy Emperor Hàm Nghi as the head of an independent Vietnam, the French colonial authorities captured Đính in an attempt to get his son to capitulate. Thuyết continued fighting, so Đính was deported. While on the sea voyage, Đính died, and the authorities threw his body overboard.
