Vientiane

Dvaravati city state kingdoms

By the 6th century in the Chao Phraya River Valley, Mon peoples had coalesced to create the Dvaravati kingdoms. In the north, Haripunjaya (Lamphun) emerged as a rival power to the Dvaravati. By the 8th century the Mon had pushed north to create city states, in Fa Daet (modern Kalasin, northeastern Thailand), Sri Gotapura (Sikhottabong) near modern Tha Khek, Laos, Muang Sua (Luang Prabang), and Chantaburi (Vientiane). In the 8th century CE, Sri Gotapura (Sikhottabong) was the strongest of these early city states, and controlled trade throughout the middle Mekong region. The city states were loosely bound politically, but were culturally similar and introduced Therevada Buddhism from Sri Lankan missionaries throughout the region.[9][10][11][12]: 6, 7 [13][14]

Contrary to the Phra Lak Phra Lam, most historians believe Vientiane was an early Mon settlement, which later came under the domination of the Khmer Empire. In the 11th and 12th centuries, the time when the Lao and Thai people are believed to have entered Southeast Asia from Southern China, the few remaining Mon and Khmer in the area moved or assimilated into the Lao civilization, which would soon overtake the area.[citation needed]

Khmer domination

The earliest reference of the name Vientiane can be seen on a Vietnamese inscription of Duke Đỗ Anh Vũ, dated 1159 during the Khmer-Viet conflict. The inscription says that in 1135, Văn Đan (Vientiane), a vassal of Zhenla (Khmer Empire), invaded Nghe An, but was repelled by the Duke; the Duke led an army chased the invaders as far as Vũ Ôn? (unattested), and then returned with captives.[15]: 65 This name may have traced it origin to Wèndān, a supposedly kingdom located in the Khorat Plateau, mentioned by a ninth-century Chinese writer described a trade route which started at Hanoi and crossed the western mountains to Wèndān.

During French rule, the Vietnamese were encouraged to migrate to Laos, which resulted in 53% of the population of Vientiane being Vietnamese in the year 1943.[18] As late as 1945, the French drew up an ambitious plan to move massive Vietnamese population to three key areas (i.e. the Vientiane Plain, the Savannakhet region, and the Bolaven Plateau), which was only interrupted by the Japanese invasion of Indochina.[18] If this plan had been implemented, according to Martin Stuart-Fox, the Lao might well have lost control over their own country.

Ban Tha Lat, Mon inscription (9th CE), was found in 1968, in an area where other pieces of archaeological evidence testified to an ancient Mon presence. It is now at Ho Phra Kaeo Museum, Vientiane, Laos

During World War II, Vientiane fell with little resistance and was occupied by Japanese forces, under the command of Sako Masanori.[19] On 9 March 1945, French paratroopers arrived and reoccupied the city on 24 April 1945
