The Kingdom of Luang Phrabang was formed in 1707 as a result of the split of the Kingdom of Lan Xang. The monarchy was so weak that it was forced to pay tribute at various times to the Burmese and the Siamese. After a particularly destructive attack by the Black Flag Army in 1887, the kingdom chose to accept French protection.

From 12 October 1945 Sisavang Vong was officially King of Laos.

Luang Prabang, or Louangphrabang (Lao: ຫຼວງພຣະບາງ, literally: "Royal Buddha Image (in the Dispelling Fear mudra)," pronounced [lǔaŋ pʰra.bàːŋ]), is a city located in north central Laos, at the confluence of the Nam Khan river and Mekong River about 425 km north of Vientiane. It is the capital of Luang Prabang Province. The population of the city is about 50,000.

The city was formerly the capital of a kingdom of the same name. Until the communist takeover in 1975, it was the royal capital and seat of government of the Kingdom of Laos. It is a UNESCO World Heritage Site.

The main part of the city consists of four main roads located on a peninsula between the Nam Khan and Mekong rivers. The city is well known for its numerous Buddhist temples and monasteries. Every morning, hundreds of monks from the various monasteries walk through the streets collecting alms. One of the major landmarks in the city is a large steep hill on which sits Wat Chom Si.

Muang Sua was the old name of Luang Prabang following its conquest in 698 A.D. by a Tai prince, Khun Lo. Khun Lo had been awarded the town by his father, Khun Borom, who is associated with the Lao legend of the creation of the world, which the Lao share with the Shan and other peoples of the region. Khun Lo established a dynasty whose fifteen rulers reigned over an independent Muang Sua for nearly a century.^{[citation needed]}
