ABOUT VIENTIANE CITY

The name of the city is derived from Pāli, the literary language of Theravada Buddhism, and its original meaning was "The king's grove of sandalwood", this tree being prized for its fragrance in classical India. It is also believed that the original name of Vientiane (Viangchan) means "City of the Moon" in the native Lao language. Modern Lao pronunciation and orthography do not clearly reflect the Pali etymology. However, the name in Thai เวียงจันทน์ still retains the etimologically correct spelling, which clearly indicates "Sandalwood City" as the original meaning. The romanized spelling "Vientiane" is of French origin, and reflects the difficulty the French had in pronouncing the hard "ch" syllable of the Lao word; a common English-based spelling is "Viangchan", or occasionally "Wiangchan".

The great Laotian epic, the Phra Lak Phra Lam, claims that Prince Thattaradtha founded the city when he left the legendary Lao kingdom of Muong Inthapatha Maha Nakhone because he was denied the throne in favor of his younger brother. Thattaradtha founded a city called Maha Thani Si Phan Phao on the western banks of the Mekong River; this city was told to have later become today's Udon Thani, Thailand. One day, a seven-headed Naga told Thattaradtha to start a new city on the eastern bank of the river opposite Maha Thani Si Phan Phao. The prince called this city Chanthabuly Si Sattanakhanahud; which was told to be the predecessor of modern Vientiane.
Contrary to the Phra Lak Phra Lam, most historians believe Vientiane was an early Khmer settlement centered around a Hindu temple, which the Pha That Luang would later replace. 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 Khmers in the area were either killed, removed, or assimilated into the Lao civilization, which would soon overtake the area.
In 1354, when Fa Ngum founded the kingdom of Lan Xang, Vientiane became an important administrative city, even though it was not made the capital. King Setthathirath officially established it as the capital of Lan Xang in 1560. When Lan Xang fell apart in 1707, it became an independent kingdom. In 1779, it was conquered by the Siamese general Phraya Chakri and made a vassal of Siam.
When King Anouvong raised an unsuccessful rebellion, it was obliterated by Siamese armies in 1827. It eventually passed to French rule in 1893. It became the capital of the French protectorate of Laos in 1899.
