> The Maya Civilization, from Central America, was one of the most advanced ancient civilizations

The Maya are still around! I spent a few months in the Guatemalan highlands last year and all the kids in the village spoke Kaqchikel, one of the Mayan languages, at home.

(Young people speaking the language is key to language health.)

throwup238•3mo ago
I was surprised to find out that there are still many indigenous groups with populations in the millions. My California public education made it seem like they were all pretty much wiped out save for those who survived to the various reservation systems.

My favorite group is the Mapuche who managed to hold out against the Spaniards until they were conquered by Chile and Argentina in the late 19th century. They managed to thwart the conquistadors for centuries! It wasn’t until the modern era where military logistics got good enough to unseat them and overcome the advantages they had.

WalterBright•3mo ago
The Commanche also held out until after the Civil War.
beerandt•3mo ago
Was always weird to me how "the French and Indian War" had Indian involvement almost over emphasized to pretend like it wasn't the extension of a European war...

While all the other American conflicts with tons of Indian involvement (both sides, esp civil war) had it downplayed.

One of my first realizations of slant put on history.

tdeck•3mo ago
It's more properly a campaign of the Seven Years War, which was almost a world war of its time.
beerandt•3mo ago
>like it wasn't the extension of a European war...
pqtyw•3mo ago
The French and Indian war began 2 years before the war in Europe. So in a way it was the other way around (of course there were much more important factors than what was effectively an ongoing proxy war in faraway colonies)
tdeck•3mo ago
My comment wasn't intended as a "correction", just adding that historians seem to refer to this war by a different name these days. At least in the textbooks I learned from, it was discussed in the context of the Seven Years War.
gausswho•3mo ago
The Mapuche even expanded their territorial control, in large part to their acquisition and mastery of Spanish horses.
pjbk•3mo ago
They also mainly continued to be loyal to the Spanish crown after Argentina and Chile went through their independence, and carried out the final pacification of the Mapuche territories in the 19th century. By then only a very small part of the population had not mingled with Europeans.
jcranmer•3mo ago
Even in the US, the Indian Wars weren't finished until the 1890s. In fact, most of the big wars against the Native Americans took place after the American Civil War. One of the big faults I have with US history in the education system is that it tends to front-load the depiction of Native Americans in the Precolonial portion of history, with an echo in the Trail of Tears and forced migration in the 1830s, and largely edits them out of the history of the settling of the west, despite this process requiring a very violent dispossession of the existing inhabitants.
t1E9mE7JTRjf•3mo ago
> most of the big wars against the Native Americans

As I learned it, most of the conflicts were between not against. Native Americans, became a term as a general catch all but those peoples saw themselves as quite diverse, and as such is something of a misnomer.

sethammons•3mo ago
Look up the american bison. The US government's official policy was to eliminate bison to eliminate Indians/First Peoples. Mountains of skulls. In under a decade, the bison population was pushed down from 30-60M to approximately 500 individuals.

Did tribes fight and war and capture slaves? Yes. They did that for forever. Then colonization and disease and westward expansion. Look up the Trail of Tears, the genocide and/or ethnic cleansing.

Your education may align with propaganda. Even today, first people nations are actively having their history taken. Pete Hegseth, sec of def/war, has pushed to close the door on the massacre of wounded knee, enshrining the medals earned for slaughtering woman and children. https://www.nytimes.com/2025/09/27/us/hegseth-wounded-knee.h....

Look up how the US government stole native kids and sent them catholic schools to have the Indian taught out of them. A system that was purpose built to stop their way of life. Or forced, non-consented sterilization of native woman that was happening in the 60s and 70s.

If you somehow didn't know the US government's history of conflict and abuse of Native Americans, you should question your formal education. And you should do some light research.

t1E9mE7JTRjf•3mo ago
you seem used to issuing commands. best of luck with that approach. your cherry picked data points may be correct, but they are also misleading absent broader historical context. these groups had largely diminished already (as is well documented by historians of the period), so your subsequent points about x/y/z impact although valid don't carry weight. imo data driven arguments trump emotional appeals. Trail of tears and similar are powerful and empathy inducing for sure, but don't change the facts around which my comment was based. your presentation skews things to a false dichotomy of one group against another which is inaccurate and unproductive. current politicians (left or right) in the US don't change history (and no I didn't bother reading your nytimes link...).

> Did tribes fight and war and capture slaves? Yes. They did that for forever.

sounds like you're confused what point you are arguing.

hitarpetar•3mo ago
> these groups had largely diminished already (as is well documented by historians of the period

this is an obvious contradiction. how could colonial historians know that "these groups had diminished" before colonialism when they weren't there? troll better

throwup238•3mo ago
I'm not sure what the GP is referencing specifically (the colonization of the Americas took hundreds of years on two continents after all) but we've got enough archaeological evidence to know that many indigenous cultures were in decline by the time the Spaniards first visited, and many entered a second decline after first contact but before they were conquered or fully economically exploited.

For example I've been studying the Mississippi river cultures [1] which left behind lots of mound villages formed into chiefdoms and paramount chiefdoms. Those cultures suffered a decline around the mid-15th century likely due to environmental changes which we can see in the distribution of villages and mounds changing. We can also see how warfare evolved based on defenses and the distribution of arable land to houses (i.e. are they clustered villages for defense or spread around their fields for efficiency?) Historians then compare them to the accounts of the Narvaez and de Soto expeditions which provides a baseline for post-contact (mid 16th), where we can also see a large decline and social restructuring before the English and French came in to finish the job (the Spaniards more or less gave up on that area as economically uninteresting except for the occasional slave raid).

[1] https://en.wikipedia.org/wiki/Mississippian_shatter_zone

hitarpetar•3mo ago
yeah, a fun fact about most locations in the world is that you can find a civilization that used to exist there and doesn't anymore
throwup238•3mo ago
I’m talking about a specific civilization’s rise and fall and what that looked like relative to the history of colonization.

You can come up with all the juvenile “fun facts” you want but what’s the point if you’re not actually going to say anything to add to the conversation?

t1E9mE7JTRjf•3mo ago
> how could colonial historians know that "these groups had diminished" before colonialism when they weren't there?

is this a serious question? what defines history as a subject is precisely that it is not the present.

estearum•3mo ago
Genocide is bad even if the victims are imperfect human beings
vacuity•3mo ago
For that matter, who can be said to be perfect?
idiotsecant•3mo ago
Prior to western colonization of course the native people had conflicts, just not at the scale the colonizers could achieve. During the genocide of the natives some tribes used it as an excuse to kill their enemies, sometimes to curry favor with a technologically superior force, and sometimes just to kill their enemies. Some fought back against the invaders, with varying degrees of success. Most people just died.

None of that makes it less of a war against the native americans.

t1E9mE7JTRjf•3mo ago
> None of that makes it less of a war against the native americans

No that's exactly what it makes it, as their conflicts subtract from those with newer arrivals. Different groups fighting each other, and then other different groups from Europe came, and made allegiances with specific local groups, then collaborated in their conflicts.

It's worth understanding that 'western colonization' wasn't a singular coherent force. There were different foreign groups with different interests - who were fighting with each other in North America.

Similarly there were 'Native Americans' (quotes as this is a colonial term) pursuing their own interests, even going to Europe. I'm not sure it's your perspective but there is a popular historic image of native americans being a defenceless people who foreigners came and wiped out which simply isn't correct, and ironically quite colonial.

idiotsecant•3mo ago
There were plenty of regional wars among the native Americans. None of them resulted in widespread genocide and construction of concentration camps and reservations. In the initial Spanish 'not western colonization' nearly 8 million people died. By the 1900s there was nearly an 80% reduction in population and western populations were in possession of their resources.

Western nations came, they defeated their enemy, and they took their territory. What else do you call that?

t1E9mE7JTRjf•3mo ago
None of what you said refutes my first point. All your points are valid, just missing broader context. 'Native American' history didn't begin when Europeans arrived. Seems to all boil down to, people A did X bad things to people B thus people A are responsible for demise of people B, while ignoring everything else that occurred with people A - who by the way are only viewed as A by people B.
vacuity•3mo ago
> people A did X bad things to people B thus people A are responsible for demise of people B

In this case, people A are responsible for most of the demise of people B, surely. I don't deny that history education should be improved on these matters, instead of choosing a villain and a victim, but your view is not much better.

t1E9mE7JTRjf•3mo ago
no that's simply not correct or backed up by any historical data. as the saying goes "it's easy to fool someone but hard to convince someone they've been fooled"
vacuity•3mo ago
Perhaps you should qualify your claims, because disease and war by Europeans to the indigenous peoples had a significant death toll and negative impact (e.g. forced migration or cultural reeducation).
WalterBright•3mo ago
> Western nations came, they defeated their enemy, and they took their territory.

The various tribes also engaged in near constant warfare with each other, defeating them, taking their territory, and making the rest slaves. Cortez was only able to defeat the Aztecs because he was able to enlist the aid of the non-Aztec tribes, who hated the Aztecs because of the depredations of Aztecs against them.

The Inca empire was only recently formed before the Spanish arrived.

In North America, the Commanche carved out an empire in the south at the expense of the tribes that had been living there. See "Empire of the Summer Moon":

https://www.amazon.com/Empire-Summer-Moon-Comanches-Powerful...

vacuity•3mo ago
Can one not say that both the tribes and the Westerners committed atrocities? I think most people in this thread who agree with the latter group would be willing to include the former group. And you are ignoring the relative scales.
WalterBright•3mo ago
Yes, there was plenty of bad behavior on both sides.
jcranmer•3mo ago
It's really hard to read this comment as anything other than "don't worry about the genocidal policy of the US with regards to the natives, for they were a violent people."

Indeed, it's actually an example of problem I lamented: the disinterest in covering Native American history post-founding of the US. The last of major conflicts between different Native American tribes took place around the 1850s, the lingering effects of the Lakota being pushed onto the Plains [1]. From that point on, all of the main conflicts are between the US and the various Native American tribes for a variety of reasons, although mainly "the US wants your land and isn't going to take 'no' for an answer."

[1] If you want to analyze the broader historical context, you of course have to ask "why did the Lakota move onto the Plains?" and following that thread of logic leads you to the first cause being "the English settled on the eastern coast."

t1E9mE7JTRjf•3mo ago
> It's really hard to read this comment as anything other than "don't worry about the genocidal policy of the US with regards to the natives, for they were a violent people."

This is a wild jump to make. I'm not sure I can take your comment in good faith as being serious.

jcranmer•3mo ago
I had the benefit of being able to write that comment after seeing the other replies you wrote to sibling comments, and those comments reinforce the impression that you believe in the inaccurate stereotype of Indians as "noble savages."
tdeck•3mo ago
This is also a difference in outcomes between traditional colonialism (where indigenous people were viewed as a source of labor) and settler colonialism (where indigenous people are viewed simply as "in the way"). That's not to say that traditional colonialism is in any way acceptable, however.
pqtyw•3mo ago
Relatively (adjusted by area and duration) not that many people from Spain moved to the Americas between 1500 and ~1800, especially compared to the British colonies in North America.

So they couldn't murder/expel (unlike the British/American colonists) most of the native population (especially considering that North America was much less densely inhabited to begin with) if they wanted someone to work in the mines and plantation (again relatively not that many slaves were imported to the mainland colonies as well).

France was similar (except they struggled even more with getting enough people to move to the colonies).

tdeck•3mo ago
The Maya are still around, but the Maya civilization's institutions were all destroyed. And the Spanish made a point of seeking out all the Maya books [1] they could find and burning them. So a lot of knowledge was lost.

[1] https://en.wikipedia.org/wiki/Maya_codices

Cantinflas•3mo ago
The link doesn't mention "seeking out" those books, in fact it mentions catholic priests both burning and lamenting the burn.
wudangmonk•3mo ago
I guess that is implied since these things always happen this way, its not like book burners are just having a nice campfire and the books they dislike just happen to be close by.
jacobolus•3mo ago
They hunted down all of the libraries, collected all of the books inside, and burned them in massive bonfires, accidentally saving a total of like 3 books which had already been shipped back to Europe as trophies. I think there are also some remaining fragments of a few others. One Spaniard wrote about it:

> We found a large number of books in these characters and, as they contained nothing in which there were not to be seen superstition and lies of the devil, we burned them all, which they regretted to an amazing degree, and which caused them much affliction.

antognini•3mo ago
It is worth noting that the friar who organized this book burning was recalled to Spain to stand trial on account of his actions.
Larrikin•3mo ago
Why is that worth noting?
hnidiots3•3mo ago
Because it might not have been the “Spanish”, but certain people who ruined history. So it’s not fair to blame a whole country for the actions of a few.
jacobolus•3mo ago
It's pretty fair to blame the entire social and political system of 16th century Spain, which at that time was centered on religious persecution, mass murder, large-scale theft and exploitation, and quasi-slavery, leading to centuries of profoundly racist tyranny in the Americas. The book-burning cultural genocide was just the cherry on top.

(As is common for feudal occupiers of foreign lands, and by no means unique to Spain) the worst kinds of psychopaths were continually elevated to positions of authority and then granted almost complete impunity to do what they wanted, with an ideology that treated the recipients of their exploitation as sub-human.

ffsm8•3mo ago
It's really not sane to do so, today.

You're literally applying birth sin for it to make sense, because none of the Spanish people alive today had anything to do with it

Even worse, what hnidiots3 was trying to convey: 99% of the population that were alive during the time period you'd have described as "Spaniards" were entirely uninvolved in these actions, and wouldn't have supported them either, likely.

While the Mayan culture was literally doing human sacrifices - the average person living in Spain wasn't inherently evil and wanting to cause suffering to other people. Despite their culture being kinda shit.

They just wanted to live their live, which was mostly being a farmer and working.

vacuity•3mo ago
Are you saying that the average person in Spain did not support colonialism (let's suppose after the benefits of colonialism became apparent)? Would they be horrified that Spaniards had killed "barbarians" and "savages" (as they were described) and gained great riches? Other people have brought up religion; how many Christians condemned the Crusades?
ffsm8•3mo ago
How specifically do you think the average Spaniard benefited by the crown building a colony? Do you think the crown then went and splurged on their farmers, reducing their taxes or something? Because no, that didn't happen.

The benefits for this was entirely with the aristocracy and wealthy, not with the average Spaniards.

vacuity•3mo ago
Going by some of the statements in this thread, if Spain-after-colonialism becomes richer and more developed, such that the average citizen's standard of living increases, then colonialism benefitted the average citizen. Benefit to the colonized peoples aside, surely many other people benefitted, even if they weren't immensely enriched.
pqtyw•3mo ago
The initial conquests and the immediate atrocities that followed them (arguably the worst period) were mainly quasi private enterprises. The state even tried to reign them in to some extent due to significant social/religious pressure at home. Of course that was largely superficial and hardly enforced after boatloads of silver and gold started arriving.

The priests and missionaries that followed them were likely the group that was most sympathetic to the natives (of course only in relative terms compared to the "conquistadors" which is a very low standard).

jasonvorhe•3mo ago
Duh. But not all Romans!
wtcactus•3mo ago
Because a previous commenter wrongly said, "the Spanish made a point of seeking out all the Maya books". It wasn't "The Spanish" it were some individual actors clearly acting against "The Spanish" crown wishes.
alex_smart•3mo ago
If that is the case, why did the trial absolve him of all crimes and why did get consecrated as a bishop by the king of Spain?
wtcactus•3mo ago
I'm guessing that his 1st person description of the human sacrifices carried out by the Mayan and establishing a connection between those and the need to erase the culture that enabled them and that he - wrongly or not, we can't know anymore - saw as enabled by those books had some weight there...

The Spanish crown didn't have in mind to destroy other people books, but then again, they also didn't have in mind that they casually, recurrently and nonchalantly offered human sacrifices to their "gods".

Probably the order of priorities for the Spanish crown was books < human sacrifices.

Strange times, those, eh?

hopelite•3mo ago
I would say because it highlights that even back then there was the same kind of tension as today between those who believe they are doing right, those who also believe they are doing right, and right never ending up being done in the end. It’s like ideological, metaphysical, and psychological border disputes and skirmishes, i.e., human nature.

Also, failing upwards of those who serve the dominant system is clearly not just a modern phenomenon.

vintermann•3mo ago
Because it's not what most people expect.

There was pushback against a lot of the evils of colonialism - most of them unsuccessful, like this one. Maybe we can learn lessons for fighting against the institutional evils of our time.

alex_smart•3mo ago
It is also worth noting that he was absolved of all crimes and eventually consecrated as a bishop.
pqtyw•3mo ago
It's complicated in the sense that there were both people trying to burn and destroy anything and those trying to preserve the books and the language doing their own stuff in parallel.
agentcoops•3mo ago
For this reason, one of the most fascinating historical relics to me are the Incan Quipu [0]. Not only because their logic appears to be 'proto-computational' (at the very least a very complex system of encoding numeric and narrative information through sequences of knots that were also used directly for calculations), but since, neither in the form of a valuable material like gold nor obviously a book to be destroyed, a large enough number survived to this day. There are few traces of the past we know exist that might contain everything from astronomical calculations to old social-institutional histories.

They're comparable in that sense to the Heculaneum manuscripts, which researchers have lately made great progress on with deep learning [1]. I hope an equivalent initiative someday starts on the Quipu.

[0] https://en.wikipedia.org/wiki/Quipu [1] https://www2.cs.uky.edu/dri/herculaneum-papyrus-scrolls/

pqtyw•3mo ago
> narrative information through sequences of knots

It's unlikely any complex narratives could be encoded there, though.

Possibly a bit like the e.g. the Mycenaean Linear B script. Which is fully decoded and well understood. But despite having a full fledged writing system they mainly used it for accounting and such. They can tell us about how many goats, sheep and various good they had they had but don't tell as much about the society or history as such.

Heculaneum manuscripts are kind of the opposite from the Quipu in the sense that we have zero issues understanding the actual text/symbols just extracting them from the destroyed scrolls is rather complicated.

Minoan tablets are maybe a bit closer and little progress has been made there (then again we are fully capable of reading the script just have no clue about the language it was written in).

agentcoops•3mo ago
I agree with your point about the Heculaneum, but my understanding is we're far enough with research into the form of the Quipus to know that they aren't simply either a linear script or merely accounting data.

For a long time, it was thought that they indeed contained only the latter, but my certainly non-specialist grasp on the matter is that we now know they were used to encode much more than that. In addition to being used directly to verify calculations [0], they contained "histories, laws and ceremonies, and economic accounts" or, as the Spanish testified at the time: "[W]hatever books can tell of histories and laws and ceremonies and accounts of business is all supplied by the quipus so accurately that the result is astonishing"[1]. My---again crude---understanding is this was through embedding categories, names and relational data in addition to numbers, signaled not least through texture and color [2].

I likely come across as if I'm trying to over-inflate the Incan knots, but really it's just to say they appear to be a rather fascinating in-between of legal-administrative inscriptions, whose discovery transformed understanding of Roman institutions over the last century or so, and the straight-forward manuscripts of the Herculaneum.

[0] My elementary and probably out-of-date recollection: an emissary would come to towns with Quipus containing work orders, which would be validated with the community on the spot.

Quipus also make an appearance (alongside core rope memory, no less) in Harkaway’s excellent Gnomon.
structuredPizza•3mo ago
My immediate observation when I first learned of the Quipu and its use: nodes and edges.

Potentially a graph to be completed by the owner via verbal communication/interpretation as a supplement to the material instrument; a single source of information that could be interpreted differently depending on the societal role and vocation of the owner.

shadyKeystrokes•3mo ago
Well, we could attempt to reconstruct it from history and similar landempires. We could take babylonian or russian history and transpose it into the language. Then recreate some superiority atrocity justification mythology ("gods chosen people"/"sinners-born-unpure"-must be purged.) Then we take all the tribes that sided with the spaniards, whose history they wiped out and invent some colorful horror-stories that other them. So, the spaniards of the new world getting trampeled by the old world, who brought gonorreha home,creating hyper puritan std ethics, voila.. nothing of value was lost.

That is not that simple. They never invented the wheel, the Maya calendar cycled over 5128, which is not really convenient, numeric system was also rather uncomfortable, strange numerals working in 19-base system (but they have invented zero). In addition to that they've invented sadistic religion with human sacrifices and their culture was very aggressive, what finally put Maya civilization to an end, as everyone around happily joined European conquerors to get rid of Mayans ASAP.
alephnerd•3mo ago

That was the Aztec, an entirely different culture from the Mayans. The Mayan Kingdoms lasted until 1697.

selimthegrim•3mo ago

AngryData•3mo ago
They had the wheel, they just didn't find many practical uses for it without having either beasts of burden or nice relatively flat paved roads.

Wheels are great if you have something stronger than a human to pull it, or you only have to move it a short distance, or if you have a hard paved road. But pulling carts or wagons or wheelbarrows through rough terrain or muddy roads with just human power is absolute trash and not worth the effort, and moving things over small short distances alone isn't worth the specialized labor and cost of making decent wheel and axle systems without machine tools.

If you are still unsure, ask yourself why hikers and campers don't pull a cart or push a wheelbarrow everywhere they go instead of using a backpack even though they can have ultra light aluminum construction with pneumatic tires and ball bearing axles. All the effort you would save by using a wheelbarrow on smooth parts of your path would be undone by just a handful of random sticks or rocks you run into with it along the way.

The Mayans and the Amazon cultures more generally have been shown to have created monumental walkways and structures that we are only now uncovering form the jungle growth via lidar. The idea that they were technologically backwards is far out of date.

I was just in Silver Spring MD, just outside of Washington, DC, and I noticed that all those kids moved from Guatamala to DC! The American dream! All the kids in Silver Spring spoke Kaqchikel, one of the Mayan languages, at home. We need more Kaqchikel-speaking children in the Silver Spring area to add to diversity, so that it's not just a primarily Spanish-speaking-only area, but a Spanish-and-Kaqchikel speaking area.

Whenever I see these backwards-applied math models I think of the “wet streets cause rain” expression.

How does one even come up with 260 day year?

Is the weather in the tropics so similar that year-on-year mismatch stops mattering?

antognini•3mo ago
The origins of the 260 day ritual year are not known for certain, but there are a couple of hypotheses:

1. Pregnancy. 260 days is roughly the gestation period of a baby, so this may have been the inspiration for tracking this duration. (For what it is worth, modern Maya timekeepers cite this as being the reason for the length of the 260 day ritual calendar.)

2. In the tropics there are two days of the year when the Sun passes through the zenith and objects cast no shadows. In the latitude where the earliest Mesoamerican civilizations emerged, the length of time between these two days of the year is about 260 days.

3. Numerology. 260 is the product of 20 and 13. 20 was significant in Mesoamerican culture because it was the base of their numbering system and was associated with the human body (given that we have 20 fingers and toes). And the number 13 was associated with the cosmos. So the number 260 represented a kind of interlocking between the human and the cosmic.

It's also worth noting that the Maya also tracked a 365 solar cycle, so they did have a concept of a more standard kind of "year." The 365 cycle was used for civil purposes. The 260 day ritual cycle was used more for divination.

(Shameless plug, but if you want to learn more about Mesoamerican astronomy I have a podcast about the history of astronomy and I talked about it on the last episode: https://songofurania.com/episode/047)

> And the number 13 was associated with the cosmos.

Any reason number 13, of all numbers, has been so significant in different parts of the world, sometimes associated with completely opposite meanings (e.g., between Jews and Persians/Europeans)?

NooneAtAll3•3mo ago
generally, 7 and 13 get a lot of attention because a)they are prime b)1/7 and 1/13 have long period when written as decimal fraction - so you keep stumbling in your calculations every time you encounter them

1/7 in base 20 takes surprisingly short form of 0.(1h) (h is 17), unlike 1/9 or 1/11 - so I wonder if there's Mayan prejudice on those instead

This reminds me a bit of how the Islamic calendar year is 355 days and doesn't have intercalation for religious reasons (many calendars insert extra months now and then to realign with the year, but the Islamic calendar does not). This is why Ramadan always seems to be at different times of year when you hear about it.

That's the explanation?

ranger_danger•3mo ago
The sad thing is that for all their advanced ways of the time, they succumbed to the same thing we are experiencing now... being too comfortable to fix what's broken.

The Mayans did not want to give up their lifestyles even in the face of crippling population growth and surrounding natural resource depletion... which led to their downfall.

t1E9mE7JTRjf•3mo ago
Sounds like the opposite no? Since we are going through population collapse in a time of abundance. Does make me wonder what the political dynamics were at the time, whether some could see problems but weren't in power to change things. Or maybe they couldn't understand or figure out solutions to the problems. What I'd give to be a multilingual fly on the wall throughout history.

We don't really have abundance tho.... We have massive over consumption that feels like abundance. Like a gambler

From newish imaging. We can see the impressions of vast jungle swaths cut down and way made for planting food and houses. This looks to have disrupted the water cycle enough to cause cinotes (underground water systems and only source of drinking water) to deplete. We see sacrificial remnants below the modern water line. Their water disappeared and so did their civilization. By the time the Spanish arrived, the local people had no knowledge of how to build nor maintain their now ancient cities, the jungles regrew, water came back, and sacrificial artifacts were covered by replenished water levels.

They are an example of man made effects on local weather leading to the downfall of an advanced civilization.

Didn't the Spanish show up briefly, then come back in force later?

I've heard some speculate that this introduced European diseases, and unlike many Native American tribes, the Mayans lived in dense cities. Such disease would spread like wildfire.

(Certainly, some disease made it the other way too! Tuberculosis and syphilis are examples)

I've heard numbers like 95% died, and it was decades between first contact and serious conquest.

That leaves a lot of time for people to grow up with no one to teach them trades, or even how to read.

If we lost 95% of our population, so many active skills would be lost.

antognini•3mo ago
The collapse of classical Maya civilization predated the arrival of the Spanish by around six centuries.
WalterBright•3mo ago
Estimates vary wildly on what percentage of the natives died from european diseases. There's just too little information on pre-Columbian populations.

For comparison, estimates of the deaths from the Black Plague in Europe are 30% to 60%. It's a huge error bar, despite having a lot of written records that survived.

> Didn't the Spanish show up briefly, then come back in force later?

The end of the Incan empire is a really striking example of this dynamic. The Spanish landed on the South American mainland in ~1524, European diseases started spreading, and in 1527 the Incan emperor died from one of the diseases without an heir. This triggered a really brutal civil war of succession that weakened the empire. The Spanish started the conquest proper of the Incan empire in ~1532 and were successful in part because how weak the empire was after the civil war.

So essentially, by arriving early and (inadvertently) initiating the disease epidemics, the Spanish put in place conditions that made the conquest possible a few years later.
