Angkor Wat collapsed after kings seized land from farmers and became over-reliant on a centralised agricultural system Login/Join

I’ll have to admit, I don’t know a lot about the history of this part of the world but was struck by some of the parallels of its early development as a society and then what finally caused it to collapse. Bold type face below is my emphasis.

The kings of Angkor Wat may have inadvertently caused the downfall of their own vast empire by seizing land from local farmers, a new study claims.

Researchers studying the ancient Khmer civilisation, which thrived in modern-day Cambodia for 600 years, wanted to discover the reason for its 15th-century decline.

The abandonment of Angkor has long puzzled historians, with many attributing it to the 1431 AD invasion by Thai forces, though this is hotly debated.

Angkor was the capital city of this now-extinct culture, and the iconic Angkor Wat temple was built in the early 12th century by King Suryavarman II.

But later, in the 1400s, kings sitting on the throne once occupied by the great Suryavarman II saw their empire crumble and eventually disappear.

Researchers believe one of the main reasons for the collapse of Khmer civilisation was a move away from independent farming to a centralised approach.

Farms were once owned and run by the middle classes, allowing people and families to support their local community which revolved around a small temple.

However, rulers increasingly made it harder for people to own land, with farming becoming an occupation reserved for the elite and, eventually, becoming totally centralized.


This shift to a state-run approach would have been more efficient at feeding a large population, but made it very rigid and unable to cope with rapid change.

It is believed that when the centralised system was tasked with feeding all of the Khmer civilisation in the face of monsoons and droughts, it failed.

This may have led to the steady and ill-fated decline of Khmer society, according to a new study.

Khmer society relied heavily on farming and developed sophisticated methods to grow crops throughout the Middle Ages.

Agriculture was the backbone of the society and the very reason the rulers accrued such incredible wealth.

The kings invested early on in an irrigation system capable of sustaining huge fields of crops.

Dr Sarah Klassen from the University of British Columbia and Damian Evans, an archaeologist at École française d'Extrême-Orient in France, studied the Cambodian site.

Writing in an article on the website Sapiens, they say: 'The scale of the hydraulic system is perhaps unparalleled in the preindustrial world.

'They built channels that were over 20 km [12 miles] in length and 40–60m [130 - 196ft] wide, above-ground reservoirs thousands of acres in size, and a vast network of walled fields used for flooded rice agriculture.

'The largest of these were constructed by kings.’

Using LIDAR (a 3D laser light scanning technique) the researchers studied the ground around Angkor to reveal what the floor-plan of the city would have been like during the peak of Khmer society.

'The generated maps reveal both areas of dense occupation with city blocks and streets, and lower-density areas with scattered community temples, sometimes marked by little more than a scatter of bricks or just a faint impression of a mound with a moat around it,' the researchers write.

The scientists focused on the locations of the newly-discovered temples, which were small and would have been the focal point of the localised community of farmers.

A machine learning algorithm was developed to date each temple as well as parts of the vast irrigation system, including ponds, moats and reservoirs.

The study found that temples were built close to these water sources, which were built by the kings.

Writing in Sapiens, they say: 'What was strange was that we found a severe decrease in the number of new temple foundations on the landscape during the 11th and 12th centuries, right when the kings were constructing major projects like Angkor Wat, hospitals, and extensive road networks.'

The explanation for why the number of temples being built dropped when large projects were being undertaken by the rulers lies in a series of inscriptions relating to land ownership and disputes.

They reveal that, in the early days of Khmer civilisation, land belonged to all echelons of society.

'However, by the mid-11th century, free males of middle rank were no longer referenced in the context of land transactions or the foundations for new temples,' the researchers say.

'By the 12th century, even free males of higher rank were referred to as temple personnel or workers rather than as landowners.

'It seems the land was increasingly concentrated into the hands of the evermore wealthy.

'First the middle class was squeezed out, and then even the upper class lost their lands to the state.'

'Our results indicate that, over time, autonomous temple communities are replaced by large, state-sponsored agricultural units in an attempt by the state to centralise production,' the researchers say in their study, published in the Journal of Anthropological Archaeology.

While this was happening, Angkor was reaching the height of its powers and by the 13th century there were lots of people living in small areas, forming cultural epicentres.

The move to centralisation coincided with a steady economic and cultural decline that lasted for centuries.

The centralised system may have been unable to cope with a booming population, changing politics and extreme weather such as monsoons and droughts.

Angkor, the ancient capital of the Khmer empire, suffered a gradual decline rather than a sudden, catastrophic demise, a new study suggests.

The abandonment of Angkor has long puzzled archaeologists and historians, with many attributing it to the 1431 AD invasion by Thai forces.

But a slow and prolonged exodus of its inhabitants has been found dating back to the start of the 14th-Century.

A decline in human activity on the land over a few decades was discovered by scientists who examined soil and sediment in the region.

A major flood is also believed to have contributed to the settlement's final collapse and abandonment.

'The historical record is effectively blank for the 15th century at Angkor,' said Dan Penny from the School of Geosciences at the University of Sydney who took part in the study.

'We don't have a written record that tells us why they left or when or how. Everything that survived is carved on stone.'

Weird. Cahokia, in south Illinois, was first a collection of small agricultural societies gathered near a floodplain of the Mississippi. Their big construction thing was earthen mounds, but there, too, people began slowly abandoning the place until it was completely abandoned by 1350-1400 AD - leaving behind no evidence of being destroyed by war, incidentally. One theory is that a major flood event on the Mississippi destroyed a lot of crops and rendered a lot of land (temporarily?) unfarmable, driving a major exodus out of Cahokia towards the end of its populated era. I wonder what other kinds of parallels might crop up over time?

The theory of a centralized farming system in Angor Wat seems at least plausible. Farming would be a major source of wealth, and controlling it would leave every one else dependent on the ruler. Growth there is probably aggressive enough that clearing land and farming it might demand an awful lot of organized labor, and that might suggest to some people that centralization could make sense. The water channels in Angor Wat itself seem to be pretty formal - straight lines, channels hardened and smoothed with rocks and (I would guess) some kind of plaster, all on a grand scale. That would jibe with a ruler wanting to convey a sense of control, and would also pit human engineering against Mother Nature's relentlessness. Since that usually leads to a catastrophic failure of human engineering at some point or another, monsoon floods could've easily created some kind of crisis event that would've undermined the ruler and driven people from the area.

The thing is, that all seems antithetical to the way cities evolved elsewhere. When a settlement can't be supported by its own farmers and hunters, it has to be supplied by the surrounding area or it will either contract or cease to exist. This means developing trade networks, and often political or military networks as well. If no one in town is a farmer, then either the word 'farmer' somehow became an unpardonable insult or the city itself was pretty much restricted to the palace and the temple. It's possible to see something similar in the imperial cities where the Emperors lived in China. It's also possible that the elites retained a bit of land that was worked by gangs, just because they were rich enough to keep a few acres when everyone else sold out their farmland to their version of urban developers.

The Maya wound up developing a system of interconnected hamlets that effectively functioned as the neighborhoods of metropolitan areas centered around their temples and palaces. I wouldn't be surprised if the people with the LIDAR simply haven't looked far enough abroad from the temple to see a similar network. That would be consistent with both a centralized system and an urbanized area that was becoming more and more of an elite enclave in its early years and less and less relevant as it declined. It would also explain where palace and temple officials got things like furniture, clothes, incidental labor, farm labor, domestic labor and maintenance personnel for the palace and temple.

You see, as far as actual application goes, LIDAR is still pretty new technology. It has really seized the imagination of antiquarians, but there have been a number of new finds (sun wheels in the American northwest, extensive transportation, irrigation, farming and urban networks along the Amazon, suburbs, new roads and temples from Mexico to Honduras, "Woodhenge", along with other graves and monuments within a couple of miles of Stonehenge in Britain) that were made just by slightly expanding the first few LIDAR searches that led to published reports. FWIW, I think they've only now begun to expand LIDAR searches to any distance out from the temple complex itself. If that's true, then there may be whole libraries' worth of information out there that we just don't know about yet.
