Chaiyaphun is probably the least visited province in Thailand. The province is flanked by two mountain ranges; Dong Phaya Yen to the west and Khao Khiew to the north, which have resulted in its remoteness. The major roads and rail network have by-passed this small province, doing little to promote travel to the area. Although the road system has been up-graded, traversing the area in a four-wheel drive (especially during the rainy season) is recommended.
Historically the province was ruled by the Khmers until the 13th century when their stronghold in the region started to wane. After the Khmers abandoned the area it remained un-populated until the late 18th century, when a large group of Laotians settled in the area. Although the community paid tribute to Vientiane, they also developed a relationship with Bangkok.
In the early 19th century Prince Anou of Vientiane declared war on the Siamese. Wise to the knowledge that Anou's troops were no match for the military superiority of the Siamese troops, the Lao ruler of Chaiyaphun, Jao Phraya Lae, switched allegiance. He later died in battle in 1806.
The Siamese sacked Vientiane in 1828, resulting in the Siamese controlling most of western Laos. The Thai's later conceded the territory to the French at the end of the century.
