On 22 October 1953 the Franco-Lao Treaty of Amity and Association transferred the last French powers to the Royal Lao Government, recognizing Laos as a fully independent and sovereign state. The act completed a path begun within the French Union, after Laos had been bound since 1893 into the colonial federation of French Indochina. Sovereignty did not bring peace: a three-cornered struggle among royalists, neutralists, and the communist Pathet Lao plunged the kingdom into civil war, compounded by the covert American bombing campaign of the wider Indochina conflict, until the monarchy itself was abolished and the Lao People's Democratic Republic proclaimed on 2 December 1975. Laos is a landlocked Southeast Asian nation whose history flows along the Mekong River, settled by Tai-Lao peoples amid the older Mon and Khmer civilizations of the region. In 1353 the warrior-prince Fa Ngum unified the Lao principalities into the kingdom of Lan Xang, the "million elephants," which embraced Theravada Buddhism and reached its height before fracturing in the early 18th century into the rival kingdoms of Luang Prabang, Vientiane, and Champasak, all soon falling under Siamese suzerainty. France absorbed the Lao lands east of the Mekong into a protectorate from 1893 as part of French Indochina, and Laos achieved full sovereignty by the Franco-Lao Treaty of 22 October 1953. Decades of civil war and the covert American bombing of the "Secret War" ended only when the communist Pathet Lao abolished the monarchy and proclaimed the Lao People's Democratic Republic on 2 December 1975, the one-party socialist state that, opening cautiously to markets and regional trade, governs Laos today.

Raised at the Khmer court, he returned to conquer and unite the Lao principalities of the Mekong, proclaiming the kingdom of Lan Xang in 1353 and bringing Theravada Buddhism to the Lao. - Setthathirath (1534-1571 CE) — King of Lan Xang. Reigning at the kingdom's height, he moved the capital to Vientiane in 1560, repelled two Burmese invasions, and built the That Luang stupa and other monuments that remain Lao national symbols. ## Three Kingdoms and Siamese Vassalage — 1707 - 1893 CE Fractured into the rival realms of Luang Prabang, Vientiane, and Champasak, the Lao kingdoms slipped into the orbit of Siam, whose armies sacked Vientiane and reduced the others to tributaries. - 1713 CE: **Champasak secedes** — The far south breaks away to form the kingdom of Champasak, completing the fragmentation of Lan Xang into three rival Lao kingdoms.

[laos-history, indochina-wars] - 1964-1973: **The Secret War bombing** — The United States drops more than two million tons of bombs on Laos to cut the Ho Chi Minh Trail, making it the most heavily bombed country per capita; vast unexploded ordnance remains a deadly legacy.

Repeatedly prime minister between 1951 and 1975, the half-brother of Souphanouvong led the neutralist faction and sought, ultimately in vain, to hold a divided Laos together amid superpower rivalry. ## The Lao People's Democratic Republic — 1975 - present A one-party socialist state closely tied to Vietnam, the Lao PDR turned from rigid central planning toward markets and regional integration, betting its future on hydropower, mining, and a new railway to China. - 1986 CE: **New Economic Mechanism reforms** — Facing the failure of central planning, the ruling party launches market-oriented reforms, legalizing private enterprise and inviting foreign investment, echoing Vietnam's Doi Moi.
