Evidence of modern human presence in the northern and central highlands of Indochina, which constitute the territories of the modern Laotian nation-state, dates back to the Lower Paleolithic. These earliest human migrants are Australo-Melanesians—associated with the Hoabinhian culture—and have populated the highlands and the interior, less accessible regions of Laos and all of Southeast Asia to this day. The subsequent Austroasiatic and Austronesian marine migration waves affected landlocked Laos only marginally, and direct Chinese and Indian cultural contact had a greater impact on the country.
Lan Xang or Lancang was a Lao kingdom that held the area of present-day Laos from 1353 to 1707. For three and a half centuries, Lan Xang was one of the largest kingdoms in Southeast Asia. The kingdom is the basis for Laos's national historic and cultural identity.
Chao Anouvong, or regnal name Xaiya Setthathirath V, , led the Lao rebellion (1826–28) against Siam as the last monarch of the Kingdom of Vientiane. Anouvong succeeded the throne in 1805 upon the death of his brother, Chao Inthavong, Xaiya Setthathirath IV, who had succeeded their father, Ong Bun or Phrachao Siribounyasan Xaiya Setthathirath III. Anou was known by his father's regnal number until recently discovered records disclosed that his father and brother had the same regnal name.
Setthathirath or Xaysettha is considered one of the great leaders in Lao history. Throughout the 1560s until his death, he successfully defended his kingdom of Lan Xang against military campaigns of Burmese conqueror Bayinnaung, who had already subdued Xieng Mai in 1558 and Ayutthaya in 1564. Setthathirath was a prolific builder and erected many Buddhist monuments including Wat Xieng Thong in Luang Prabang, Haw Phra Kaew, Wat Ong Teu Mahawihan and the Pha That Luang in Vientiane.
Photisarath, son of King Visoun of Lanxang, is considered to be the most devout of the Lao kings. He banned spirit worship and built temples upon the sites of spirit shrines. His elephant fell and crushed him while he sought to display his prowess to the diplomatic corps. His son Setthathirath returned from Chiang Mai to succeed him to the throne of Lan Xang.
Meuang Phuan or Xieng Khouang, also known historically to the Vietnamese as Trấn Ninh, was a historical principality on the Xiang Khouang Plateau, which constitutes the modern territory of Xiangkhouang Province, Laos.
The Kingdom of Champasak or Bassac, (1713–1904) was a Lao kingdom under Nokasad, a grandson of King Sourigna Vongsa, the last king of Lan Xang and son-in-law of the Cambodian King Chey Chettha IV. Bassac and the neighboring principalities of Attapeu and Stung Treng emerged as power centers under what was later to be described as the Mandala Southeast Asian political model.
The Lao Rebellion of 1826–1828 was an attempt by King Anouvong of the Kingdom of Vientiane to end the suzerainty of Siam and recreate the former kingdom of Lan Xang. In January 1827 the Lao armies of the kingdoms of Vientiane and Champasak moved south and west across the Khorat Plateau, advancing as far as Saraburi, just three days march from the Siamese capital of Bangkok. The Siamese mounted a counterattack to the north and east, forcing the Lao forces to retreat and ultimately taking the capital of Vientiane. Anouvong failed in both his attempt to resist Siamese encroachment, and to check the further political fragmentation among the Lao. The kingdom of Vientiane was abolished, its population was forcibly moved to Siam, and its former territories fell under the direct control of Siamese provincial administration. The kingdoms of Champasak and Lan Na were drawn more closely into the Siamese administrative system. The kingdom of Luang Prabang was weakened but allowed the most regional autonomy. In its expansion into the Lao states, Siam overextended itself. The rebellion was a direct cause of the Siamese-Vietnamese wars in the 1830s and 1840s. The slave raids and forced population transfers conducted by Siam led to a demographic disparity between the areas that would ultimately become Thailand and Laos, and facilitated the "civilizing mission" of the French into Lao areas during the latter half of the nineteenth century.
Setthathirath II, also called Ong Lo and Sai Ong Hue, grandson of the great ruler Suliyavongsa, was the king of the Lao Kingdom of Lān Xāng. In Vietnamese records, he was called Triều Phúc (朝福).
The Kingdom of Luang Phrabang, also called Kingdom of Luang Prabang was formed in 1707 as a result of the split of the Kingdom of Lan Xang. When the kingdom split, Muang Phuan became a tributary state of Luang Prabang. Over the years the monarchy weakened even more, and was forced to become a vassal various times to the Burmese and the Siamese monarchies.
Sen Soulintha, Saen Surintha or Sen Sourintha (1511–1582) was born Chane Tian and became King of Lan Xang reigning from 1571 to 1575 and again from 1580 to 1582. Sen Soulintha was not of noble birth, rising from royal page to the position of King Setthatirath's Chief Minister. During the succession disputes in the Kingdom of Lan Na between King Setthatirath and King Mekuti, Sen Soulintha served Setthatirath as a general and successfully took several cities of Lan Na including Chiang Saen for which he was given the honorific name Lusai meaning “victory.” Sen Soulintha supported Setthatirath in leading the guerrilla campaigns during the Burmese invasions of King Bayinnaung. When Setthatirath died near Attapeu under suspicious circumstances in 1572, Sen Soulintha led the armies of Lan Xang back to Vientiane. A succession dispute erupted, which nearly led to civil war and provided a pretext for another Burmese invasion ordered by Bayinnaung and led by the Chief Minister Binnya Dala. Sen Soulintha defeated the Burmese and Lan Na forces led by Binnya Dala, an event which led to the latter's exile, only to face a more massive invasion led by Bayinnaug the following year. Sen Soulintha again attempted to resort to guerilla tactics, but lacked popular support from his seizure of the throne. He and his son Ong Lo were captured by Bayinnaung and exiled to Pegu. The Burmese placed Setthathirath's brother, and former Ouphahat or Viceroy, Prince Tha Heua on the throne. According to the Luang Prabang chronicles it was this brother, who had led a rebellion in Luang Prabang and tried to seize the throne from Setthathirath on the death of their father Photisarath. Prince Tha Heua took the regnal name Voravongsa and reigned under Burmese suzerainty from 1575 to 1579. Voravongsa was never popular, and drowned with his family while attempting to flee Vientiane in the face of popular uprising. In 1579, Bayinnaung dispatched a sizable army to restore order. According to Lao histories Sen Soulintha was then installed as king a second time in 1580. By that time Sen Soulintha was an old man and reigned only for two years before his son ascended the throne as Nakhon Noi and another succession dispute ensued.
Voravongsa I was king of Lan Xang reigning from 1575–1579 with the regnal name Samdach Brhat-Anya Chao Brhatasena Vora Varman Raja Sri Sadhana Kanayudha but he is commonly referred to in both Lao and Burmese chronicles by his title of Maha Oupahat or Viceroy. Voravongsa was taken prisoner by the Burmese in 1565 during the occupation of Vientiane. In 1575 following the third of a series of Burmese invasions of Lan Xang, Voravongsa was appointed by Bayinnaung as a vassal within the Taungoo Empire. Voravongsa had few supporters even within the Burmese court; he reigned for only four years before facing a popular rebellion which would threaten to overtake the capital in Vientiane. Voravongsa attempted to flee back to Burma, but were killed en route. To reestablish order the Burmese dispatched another army, and would install Sen Soulintha as vassal from 1580–1582.
Nanthasen, also known as Chao Nan, was the 6th king of the Kingdom of Vientiane. He ruled from 1781 to 1795.
Phrachao Siribounyasan, also known as Ong Boun (ອົງບຸນ), Bunsan or Xaiya Setthathirath III, was the 3rd king of the Kingdom of Vientiane.
Chao Inthavong, or known as his regnal name Xaiya Setthathirath III, was the 5th king of the Kingdom of Vientiane.
Chao Kingkitsarat, also known as Kitsarat or Kitsarath, was the king of Luang Phrabang.
Lat money refers to the bar-shaped coinage minted and used as currency in the kingdom of Lan Xang and its successor kingdoms of Vientiane, Luang Prabang, and Champasak. "Lat" is a Lao abbreviation for "talat" or "market," referring to the small denomination currency which may also be referred to as "boat money" or "Ngern Heua." The bar-shaped coinage of Lan Xang could be differentiated according to shape, weight, metal, alloy, and mint marks.
Lao–Siamese War or the Siamese Invasion of Laos (1778–1779) is the military conflict between Thonburi Kingdom of Siam and the Lao kingdoms of Vientiane and Champasak. The war resulted in all three Lao kingdoms of Luang Phrabang, Vientiane and Champasak becoming Siamese tributary vassal kingdoms under Siamese suzerainty and domination in Thonburi and the subsequent Rattanakosin Period.
