Lan Xang - Middle Years

Middle Years

The kingdom of Lan Xang, made up of diverse Lao, Tai, and ethnic hill tribes, lasted for another 600 years, briefly reaching an even greater extent in the northeast. The principality of Muang Phuan, brought under Lan Xang in the mid-14th century, enjoyed semi-independent status. Fa Ngum's descendants remained on the throne for almost 600 years after his death. They maintained the independence of Lan Xang to the end of the 17th century by a complex network of vassal relations with lesser princes. During this time, they fought off invasions by Vietnamese Emperor Le Thanh Tong, 1478–79, Ayutthaya King Chairacha in 1536, and Burmese King Bayinnaung, 1571–1621.
