History
The south was part of the Khmer world long before it was Lao. At the foot of Phou Kao, a mountain whose summit resembles a linga, a city now called Shrestapura grew up by the 5th century, and the temple of Wat Phou, rebuilt mainly in the 11th and 12th centuries, was linked by road to Angkor. Lao settlers moved down the Mekong in the centuries after the founding of Lan Xang, and when that kingdom split in the early 18th century, Champasak became a separate Lao kingdom. It fell under Siamese control later that century.
In 1893 France took the east bank of the Mekong, and in 1904 the Champasak territory west of the river followed, although the royal house of Champasak survived. The French founded Pakse as a provincial seat in the early 20th century and planted coffee on the Bolaven plateau; from 1893 they also ran a short railway across the islands of Don Det and Don Khon to carry cargo around the Khone falls. Savannakhet grew as a trading post opposite Siam.
The uplands of Savannakhet, Salavan, Sekong and Attapeu carried the Ho Chi Minh Trail in the 1960s and 1970s and were among the most heavily bombed places in the country. Kaysone Phomvihane, the communist leader who ruled Laos from 1975 until 1992, was born in Savannakhet, and the city now bears his name officially. In 2018 the collapse of a dam at the Xe-Pian Xe-Namnoy project flooded villages in Attapeu, killing dozens of people and displacing thousands. Wat Phou and the Champasak landscape became a UNESCO World Heritage Site in 2001.
