A kingdom named for a million elephants ruled Laos for centuries
Lan Xang held much of present-day Laos from 1353 to 1707—about three and a half centuries as one of mainland Southeast Asia's largest realms. Its Lao name evokes "Million Elephants and the White Parasol," signaling royal power, Buddhist kingship, and war elephants.
Fa Ngum is conventionally credited with founding the kingdom in 1353 after exile among the Khmer, marriage to princess Keo Kang Ya, and a 1349 campaign with an army nicknamed the "Ten Thousand." He took Champasak, Thakek, and Kham Muang along the Mekong, secured help from Muang Phuan, fixed a border with Đại Việt along the Annamite Range, and overwhelmed Lanna at Chiang Saen. By 1357 the mandala stretched from Sipsong Panna near China down past Khong Island's rapids at Sambor, and from the Annamites to the western rim of the Khorat Plateau. Ayutthaya's Uthong sent 100 elephants, gold, silver, over 1,000 ivory pieces, and a daughter as a second wife after acknowledging Lao control of the plateau.
Authority ran through mueang tied to the king rather than a tight central bureaucracy; the Mekong carried trade and shaped politics. Capitals shifted from Luang Prabang until 1560 to Vientiane thereafter. Theravada Buddhism was the state religion, with the Phra Bang as palladium. Origin chronicles open with Fa Ngum's birth in the Year of the Nāga 1316 and root legitimacy in the Khun Lo line under legendary Khun Borom. Tai migrations into the region accelerated after the Mongol conquest of Yunnan in 1253–1256.
Fa Ngum was deposed in the 1360s after war with Sukhothai; his son Oun Huean was crowned Samsenthai ("King of 300,000 Tai") in 1371 and won Ming recognition in 1402. Under Lan Kham Daeng in 1421, Lan Xang sent about 30,000 troops and 100 elephant cavalry ostensibly to aid Lê Lợi against the Ming, then sided with China instead—fuel for later Vietnamese vengeance. From 1428 to 1438 seven kings fell to intrigue linked to Queen Maha Devi (Nang Keo Phimpha); she may briefly have ruled before drowning in the Mekong in 1438. Burma invaded in the sixteenth century, and in 1707 the realm split into Luang Prabang, Vientiane, and Champasak.
