Cambodia
Kingdom · 1431–1863
The "Middle Period" or post-Angkor era of Cambodian history is conventionally dated from the Siamese sack of Angkor around 1431, which pushed the Khmer court south-east to the Mekong–Tonle Sap confluence. The capital moved successively from Chaktomuk (Phnom Penh) to Longvek (1525), Srey Santhor (1594), and finally Oudong (1620–1863).

Origins & foundation
The "Middle Period" or post-Angkor era of Cambodian history is conventionally dated from the Siamese sack of Angkor around 1431, which pushed the Khmer court south-east to the Mekong–Tonle Sap confluence. The capital moved successively from Chaktomuk (Phnom Penh) to Longvek (1525), Srey Santhor (1594), and finally Oudong (1620–1863). Sources for the period are sparse and mostly external (Chinese Ming records, Ayutthayan chronicles, European accounts), and the reliability of the Cambodian Royal Chronicles is much debated by historians such as Michael Vickery and David Chandler.
Political history & notable rulers
The Longvek era under Ang Chan I (1516–1566) was a brief revival: Longvek prospered as a maritime-trade hub and Cambodian armies repeatedly raided a weakened Ayutthaya between the 1560s and 1580s, even sacking Phetchaburi in 1581. Siamese retribution came in 1594, when King Naresuan captured Longvek and carried the royal family to Ayutthaya. In 1642 a usurper converted to Islam and reigned as Ramathipadi I, the apogee of Muslim rule in mainland Southeast Asia; he defeated the Dutch East India Company in the Cambodian–Dutch War (1643–44) before Vietnamese-backed rebels deposed him in 1658–59. By the 18th century the kingdom was a buffer: Ang Eng (1779–1796) was installed at Oudong under Siamese tutelage while Siam annexed Battambang and Siem Reap.
Economy, culture & religion
Post-Angkor Cambodia shifted from Angkor's inland hydraulic agrarianism toward commerce: Longvek hosted Chinese, Malay, Japanese, Arab, Portuguese, Spanish and Dutch trading communities, exporting ivory, lacquer, silk and rhinoceros horn. Theravada Buddhism was the state religion, though a substantial Muslim Cham and Malay community existed. Vietnamese settlement of the Mekong Delta (Kampuchea Krom) progressively cut Cambodia off from the sea from 1623 onward.
Peak & territorial extent
At the dataset's 1700 window the kingdom still nominally covered the lower Mekong basin, Tonle Sap and Cardamom regions (approx. 89,000 km² in the dataset), but real royal authority was narrowing steadily.
Decline & end
The 19th century brought joint Siamese–Vietnamese suzerainty; Minh Mang's occupation (1834–1841) attempted the "Vietnamization" of Cambodia, provoking mass rebellion. Independence was restored under Ang Duong in 1847, but he sought French protection, and in 1863 King Norodom signed the French protectorate, ending the Middle Period.
Legacy & modern connections
The period explains Cambodia's enduring anxieties about Thai and Vietnamese encroachment, the loss of the Mekong Delta (still a live national grievance), and the enduring prestige of Angkor as a religious centre — inscriptions at Angkor Wat continued as late as 1747.
