Royal Standard of Laos

Lan Xang was the name of the Laos Kingdom during its early years. The kingdom was ruled by the first king, Fa Ngum until the reign of King Sai Setthathirat. The Lan Xang kingdom's royal seat was based in Luang Phrabang, after which the royal seat moved to Vientiane. With the rule of Sourigna Vongsa for more than 57 years, Laos entered its golden age. In 1707, Lan Xang split into the separate kingdoms of Vientiane, Luang Phrabang and Champasak.
