Trương Minh Giảng

Trương Minh Giảng (張明講, ? – 1841) was a general and official of the Nguyễn Dynasty, Vietnam.

Giảng was born in Gia Định (modern Ho Chi Minh City). He passed exam with the grade of hương cống in 1819.

A rebellion was launched by Lê Văn Khôi in Gia Định in 1833. It was an important revolt in southern Vietnam, Giảng was sent to put down the rebellion together with Tống Phúc Lương, Nguyễn Xuân, Phan Văn Thúy and Trần Văn Năng.

Two Siamese generals, Bodindecha and Phra Klang, led troops to attack the Vietnamese provinces of Hà Tiên and An Giang and Vietnamese imperial forces in Laos and Cambodia. Giảng defeated Siamese army in Cambodia, and installed Ang Chan II as the puppet king of Cambodia. Giảng stayed in Phnom Penh to surveil the king.

Ang Chan II died without heir in 1835. Giảng installed Ang Mey as puppet queen. He ordered all Cambodian women to wear Vietnamese-style pyjamas instead of the khmer sampot (similar to the sarong), grow their hair long in Vietnamese style. Phnom Penh was renamed to the Vietnamese name: Trấn Tây Thành (鎮西城), or "Western Commandery". Wats were destroyed during this period, and numerous ethinic Vietnamese came into Cambodia.

Cambodia became a part of Vietnam in 1841, and Ang Mey was deposed and exiled to Gia Định. Many Cambodian were infuriated, and revolted against the Vietnamese rule. Seizing the opportunity, Siam invaded Cambodia in an attempt to install Ang Duong on the throne as their own puppet, triggering the Siamese–Vietnamese War (1841–45). Giảng tried to suppress but failed. Emperor Thiệu Trị decided to withdrawal Vietnamese army from Cambodia on the advice of Tạ Quang Cự. Giảng died on his way back to Huế.
