Trðáng Minh Giảng (, 1792 â 1841) was a general and official of Vietnam during the Nguyá» n dynasty.
Trðáng-Minh Giảng was born in Gia ÃÂá»Ânh (modern Ho Chi Minh City). He came from an important aristocratic family of southern Vietnam, the Trðáng-Minh family from which also comes the scholar Trðáng Minh Ký (1855-1900). His father, Trðáng-Minh Thành was the minister of ceremony (Lá» bá»ÂàThðợng thð) of Emperor Gia Long. Giảng passed the triennial exam with the grade of ' in 1819. He became a military mandarin in the service of Emperor Minh-Mang and was appointed major general.
A rebellion was launched by Lê VÃÂn Khôi in Gia ÃÂá»Ânh in 1833. This was an important revolt in southern Vietnam, Giảng was sent to put down the rebellion together with Tá»Âng Phúc Lðáng, Nguyá» n Xuân, Phan VÃÂn Thúy and Trần VÃÂn NÃÂng.
Two Siamese generals, Bodindecha and Phra Klang, led troops to attack the Vietnamese provinces of HàTiên and An Giang and Vietnamese imperial forces in Laos and Cambodia. Giảng and his 10,000 soldiers defeated the Siamese army in Cambodia, and installed Ang Chan II as a client king of Cambodia. Giảng was appointed Governor-General of Cambodia and stayed in Phnom Penh to watch the king.
In 1835 Ang Chan II died without heir. Giảng installed Ang Mey as a client 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 with a Vietnamese name: Trấn Tây Thành (é®西åÂÂ), or "Western Commandery". Many Wats (temples) were destroyed during this period, and numerous ethnic Vietnamese came to Cambodia.
Cambodia became a part of Vietnam in 1841, and Ang Mey was deposed and exiled to Gia ÃÂá»Ânh. 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 SiameseâÂÂVietnamese War (1841âÂÂ45). Giảng tried to resist but failed. The new emperor Thiá»Âu Trá» suddenly decided to withdraw all Vietnamese troops from Cambodia following the advice of Tạ Quang Cá»±.
Giảng died suddenly on his way back to Huế. Sources stated that he committed suicide by taking poison together with other two senior generals to avoid punishment from the emperor.
