Title: Vientiane
Content:  Vientiane (, ; ວຽງຈັນ, ) is the capital and largest city of Laos, on the banks of the Mekong River near the border with Thailand. Vientiane became the capital in 1573, due to fears of a Burmese invasion, but was later looted, then razed to the ground in 1827 by the Siamese (Thai). Vientiane was the administrative capital during French rule and, due to economic growth in recent times, is now the economic center of Laos. The city had a population of 948,477 as of the 2020 Census. Vientiane is noted as the home of the most significant national monuments in Laos – That Luang – which is a known symbol of Laos and an icon of Buddhism in Laos. Other significant Buddhist temples in Laos can be found there as well, such as Haw Phra Kaew, which formerly housed the Emerald Buddha. The city hosted the 25th Southeast Asian Games in December 2009, celebrating 50 years of the Southeast Asian Games.

The city is part of Luang Prabang District of Luang Prabang Province and is the capital and administrative centre of the province. It lies approximately 300. km north of the capital Vientiane.

Following Siam's acceptance of the ultimatum, to cede the lands east of the Mekong including its islands, the Protectorate of Laos was officially established and the administrative capital moved from Luang Prabang to Vientiane. However, Luang Prabang remained the seat of the royal family, whose power was reduced to figureheads while the actual power was transferred over to French officials including the vice consulate and Resident-General.

Title: Kingdom of Laos
Content:  The Kingdom of Laos was a constitutional monarchy that ruled Laos beginning with its independence on 9 November 1953. It survived until December 1975, when its last king, Sisavang Vatthana, surrendered the throne to the Pathet Lao, who abolished the monarchy in favour of a Marxist–Leninist state called the Lao People's Democratic Republic, which has controlled Laos ever since. Given self-rule with the new Constitution in 1947 as part of the French Union and a federation with the rest of French Indochina, the 1953 Franco-Lao Treaty finally established a sovereign, independent Laos, but did not stipulate who would rule the country. In the years that followed, three groups led by the so-called Three Princes, contended for power: the neutralists under Prince Souvanna Phouma, the right-wing party under Prince Boun Oum of Champassak, and the left-wing, North Vietnamese-backed Pathet Lao under Prince Souphanouvong and future Prime Minister Kaysone Phomvihane. The Pathet Lao would eventually emerge victorious in the Laotian Civil War and establish the Lao People's Democratic Republic in 1975.
