Hoàng Diệu  Hoàng Diệu (chữ Hán: 黃耀, 1828 – 25 April 1882), born Hoàng Kim Tích, (黃金錫) was a Nguyễn Dynasty governor of Hanoi, on behalf of Emperor Tự Đức, resident in Huế. Diệu was born in 1828 into a family of officials in Điện Bàn District, Quảng Nam Province. In 1848, he passed the "thi Hương" or Township Test. In 1853, he became a "phó bảng" ("Top Scholars") and thereafter, a "cử nhân" ("senior bachelor"). In 1864, he suppressed Nguyễn Phúc Hồng Tập's rebellion. He was then posted to Bắc Giang Province, Nam Định Province and Bắc Ninh Province respectively. In 1879, Hoàng Diệu was appointed as the governor of Hanoi. He committed suicide by hanging when the French under captain Henri Rivière, having exceeded his superiors' orders, suddenly took the citadel of Hanoi on 25 April 1882. Hoàng Diệu is venerated alongside Nguyễn Tri Phương by the Vietnamese people as loyal subjects who sacrificed themselves for Vietnam. Many cities and streets in Vietnam are named after him. His grandson was the Paris-trained philosopher Phan Khôi.
