I am considering whether a pre-Industrial civilisation could carry on for millennia on an Earth-like planet without entering the Industrial Age.

Of course, regularly destroying everything with plagues, earthquakes, etc and sending people back to the Bronze Age might do the trick, but I am looking for something more subtle.

For example, would a lack of readily-accessible iron ore prevent steam combustion engines from being practical? And is it believable on an Earth-like planet that iron ore would be that inaccessible?

An early Industrial Revolution needs cheap energy. Fossil fuels and coal were essential to it.

Just make fossil energy hard to find, or too expensive to extract, and all economic incentives to start changing all the technology and all the society will vanish. First steam engines were placed in coal mines to extract water from them and avoid flooding. They were made just because it was cheaper to use coal powered machines than using animal or human powered devices.

Societies before the Industrial Revolution were dependent on the annual cycle of plant photosynthesis for both heat and mechanical energy. The quantity of energy available each year was therefore limited, and economic growth was necessarily constrained. In the Industrial Revolution, energy usage increased massively and output rose accordingly. The energy source continued to be plant photosynthesis, but accumulated over a geological age in the form of coal. This poses a problem for the future. Fossil fuels are a depleting stock, whereas in pre-industrial time the energy source, though limited, was renewed each year.

Energy and the English Industrial Revolution E. A Wrigley Philosophical Transactions of the Royal Society 2013.

From these first uses, steam engines were developed into sea and land vehicles. Other kind of engines, like internal combustion ones, were developed only after fossil fuel powered vehicles became relevant.

If there were not any cheap coal or petrol, engineers still could develop engines powered by olive oil or alcohol, but they would not be economical enough to substitute horses, oxen or wind. Society would not change abruptly so there would not be any "revolution". Greeks and romans knew some sort of steam engines but their slave powered economy didn't need any development of these machines.

Ways to make fossil fuels impractical:

Centuries before the revolution you could seed coal and oil deposits with genetically engineered bacteria that would metabolize that energy and turn it into useless carbon dioxide and carbohydrates. Manna mines could be created but not fuels.

The Industrial Revolution wouldn't have occurred as it did without philosophical and political changes having occurred a few centuries earlier. Before those changes, Europe was much more decentralized politically and industry was in general controlled by the Guilds. The point of the guilds was to ensure adequate skilled work for all craftsmen of a given trade. This resulted in a basic degree of prosperity, more equitably divided across the society. The guild system did allow for new techniques and ideas, but they spread more slowly because the understood purpose of labor and craft was not to acquire wealth for oneself nor to advance technology, but rather the purpose was to provide for material needs, some degree of self-fulfillment and cultural support.

The abolition of the guilds allowed powerful people to gain wealth and control over industry and politics. It's noteworthy that the level of prosperity of the working man in 1545 wasn't reached again until 1945 with the post-war prosperity boom.

So for your story, if you have a deeply-rooted cultural philosophy which emphasizes other ideas above advancing technology or gaining wealth, ideas such as cooperation, mutual support, environmental concern, individual liberty, etc, it could make industrialization unlikely because it would require massive philosophical changes to be accepted.

Labor is cheap enough; new machines are expensive

Something to think about... records from the Great Library in Alexandria, Egypt, show that "industrial" devices such as steam engines were not only theorized, but constructed. However, because the cost of labor was very cheap in Egypt (which was mostly due to the Nile being an amazing food source and transportation network), there was never really any need to supplant human labor with machine labor. Although we can't know this for sure, since most of the records from the Great Library were burned down, we can speculate for the purpose of your story that the elites of this pre-industrial society foresaw the social and economic upheavals inherent in such a new system and sought to prevent any change that could potentially harm their social status.

Which could potentially lead to an ideology that believes...

Only things built with human hands matter

Ruins of the ancient Mayans are all the more impressive when considering that the Americas had NO draft animals. That meant everything had to be done with human hands and feet. No oxen to till the soil, no horses to ride from A to B. Although they did understand basic innovations like the wheel, the Mayans believed that human effort created real value, and it was integral to their religion and way of life. They believed that the gift of Creation from the Gods was accompanied by a "Blood Debt," which had to be repaid throughout all their lives (and often through death by conquest or sacrifice). They were able to create fantastically accurate mathematical models (including the use of zero! ZERO! The number that eluded even the smartest of the Greek and Roman philosophers!), but they still chose to build their impressive cities and towers by hand.

Really makes you think what human beings are truly capable of.

An interesting thought might be to eradicate tea from your world. Some historians think that tea had a pivotal role in making industrial revolution possible. Factories had long and demanding working hours and so after tea became available to everyone, the caffeine in it helped workers to get through a shift. Another - more important - aspect of a high percentage of the population drinking tea was its role in preventing mass pandemic. Since people boiled water for their tea, they killed most bacteria in the water, and it was the only way to stop a quickly spreading epidemic in a densely populated area.

I don't think you can prevent the start of an industrial revolution without meddling with the world and its rules a lot, but there certainly are ways to stop the continuation of it, mainly health and social reasons.

Let's define what we mean by Industrial Revolution. I'm going to say this is a period of time where there was a massive shift from hand production of goods to mechanized production of goods (so things like the steam engine and spinning jenny never being invented).

Do I believe this could be prevented forever? Absolutely not, it would happen unless civilization kept getting reset. Could we delay it for a few centuries? Now, that's possible.

There were a lot of driving forces for the Revolution, and I'm not going to argue over them (because I'm not a historian, I'm a software engineer), but the ones that look the most important to me are an available workforce (population), spread of knowledge, and an increase in social freedoms and economic standing.

Knowledge

As was true in the Renaissance, the spread of knowledge empowers social change. If you have a society or system that tamps down on knowledge sharing (an autocratic regime or strict religion might work) you can reduce the likelihood that enough people create enough machines to make the revolution happen.

Maybe there's a guild or trade group that restricts such knowledge, to protect their manufacturing. Maybe inventors aren't incentivized to create new things, because any time they do their ideas are stolen and make someone else rich.

Available Workforce

Revolutions in agriculture and a population boom assisted the Industrial Revolution by providing a workforce for new factories. If most of your population is drawn off for agriculture or military service (or if there's just not a lot of population growth because of disease or a society that restricts how many children you can have) you won't have the labor force to do anything if those industrial processes are created.

Social Freedoms and Economics

In medieval times, serfs remained on the land of their lord. They were largely not permitted travel without permission, and were tied to the land. This limited the spread of ideas, and also limited the wealth of the lower classes. Why does this matter? Machines are expensive. If there's no captialist draw to owning a machine and making profits from it, there's less chance of it happening. Do you think a comfortable noble, who makes money doing absolutely nothing, will give that money to someone else so they can build a fanciful machine to make goods others? Not when it's cheaper to hire a seamstress or cobbler to make the handful of goods he needs himself (which would probably be higher quality than the machined ones). A rich man might want to become richer, but before the Industrial Revolution, there were other ways of doing it that were more familiar and comfortable.

The Solution?

My solution would be to have the majority of the story take place inside an Empire with a theocratic and oligarchic elements in the government, such as composing something like the houses of a legislature (e.g. the theocratic side could be something like the House of Lords, while the Trade Guilds could form a House of Commons).. While the Emperor is not directly tied to the religious sect or the trade guilds, his actions are heavily influenced by them. The religious sect has a tight control over the printing of books and manuscripts, and any found without their mark are considered illegal and immoral. The owner is considered a heretic. Religion should be very important to the people, to help prevent revolution.

The Trade Guilds control specialized knowledge over their domains, and tamp down tightly on any inventions or ideas that would hurt this control. They actively hunt for inventors, bringing them into the guilds or removing them as a problem. They pride the quality of their wares (as most of their profit comes from the nobility), so unless an invention improves the quality of the goods, it will likely not be put into production. These Trade Guilds also crack down on people selling finished goods without their approval (but do allow production of "home use" goods, just don't try selling them). Parents should relish the opportunity to send their children into apprenticeship programs, and such programs should be highly selective. Most of the people should be simple farmers.

The final key is preventing revolution. This Empire is heavily xenophobic, and is surrounded by weaker kingdoms of different cultures. Every few years, the Empire will attack one of these kingdoms (or be attacked by it). Depending on your technology scale, these could be anything from long, drawn-out medieval sieges, where thousands die from disease and starvation, to gun-powder era battles where thousands die from grape shot and the like (a lack of an industrial manufacturing base would mean capturing enemy equipment might be very lucrative. If you can't mass produce cannon, capturing your enemy's might be a good thing).

Finally, the Emperor should be very kind and generous to his people to prevent revolution. Host festivals and games, help the poor, have a pension plan for the military veterans, etc. The xenophobic part should help a lot too, because social revolution is less likely when there are enemies at the gates.

Considering that the world history did see destruction through earth-quakes, plagues, wars and so on and the industrial revolution still happened, that is probably not the way to go.

If you look at the preconditions, the revolution was the end of a long list of mechanical improvements over many centuries. You could certainly delay it considerably, and slow it down so much that it won't appear as a revolution in history books by taking away coal, steel and other essential parts of early machinery. But burning wood in iron steam engines works as well. It will just be less efficient, making the whole process a lot longer.

So you can change history so that there was never an industrial revolution, just a slow, constant process eventually leading to an industrialised world. I doubt you can keep a world in a pre-industrial development forever without some serious interventions.

I don't think that the industrial revolution - or some version of it - can be delayed infinitely.

The problem you are facing is something i saw descried as "steam-engine time", which describes the time in the progress of mankind (or a sizeable subset thereof) where every knowledge you need to invent a steamengine was readily available.

I don't think it was feasible to prevent progress completely, and while you may remove mineral oil and coal (simply have bacteria breaking down trees a lot earlier and oil nor coalhappen, more or less), but there are other forms of energy. You could still burn charcoal in your steam engines, and bioethanol in your internal combustion engine. You might remove iron, but steam engines can be made from brass or other metals, too.
Granted, that will slow down your industrial revolution, but it won't prevent it.

Electricity was discovered at some point (you may remove amber and cats from your world to slow this discovery down, but it will be discovered eventually, although what would be the point of having a world without cats?), and after that someone will eventually come up with the idea of hooking up a generator to a windmill.

If steam engines for some reason were not feasible, you would get a much cleaner industrial revolution, but it would happen nonetheless.

So, unless you change your setup beyond recognition, i think the answer is

no.

A few ways to slow the arrival of the industrial revolution:

  1. Keep the population low. Technological advancement is accelerated by scale. This could be done by cultural or physical means, for example the edible vegetation could inhibit reproduction.
  2. Keep the population dispersed. Small groups of people will advance much more slowly. This could be motivated by contagious diseases or scarcity of food.
  3. Increase the difficulty of organization, and decrease the motivation. For example, disease is very common making social organization difficult, but food is plentiful making it unnecessary.
  4. Lack of good choices for domesticated animals. This was the first step in organized production. In "Guns, Germs, and Steel" Jared Diamond makes this argument for why European industrialization was ahead of Native American. That's a worthwhile read on this topic in general.

Running some of these together, perhaps this is the second time around. An advanced civilization consumed all the easily accessible coal, oil, and other resources and then collapsed. Possibly they made the best choices for animal domestication extinct during their collapse.

Id say that the ignorance of people can put off any development in any age.

As Ginasius said: An early Industrial Revolution needs cheap energy.

In order to remove this, ignorance of it's importance is enough for people to ignore it's importance or willing fully deplete the resource before they learn to harness it properly.

Easter Island

A good example of how ignorance stopped a society from developing is the history of the Easter island. When the Polynesian natives first arrived there, the island was covered in trees, and the eco system could easily support the them. For religious purposes, they harvested the trees for transporting the big heads to the coast. The extreme deforestation caused by the people devastated the ecosystem. At some point they must have had a single tree left on the island. And they cut it down anyway. Their civilization never really recovered from it. It went as far as reducing the people to cannibalism in some instances.

Chinese civilization

When comparing the European development to Chines development, you'll notice that China fell behind in the industrial revolution. The reasons why this happened are because of very complex things, that are best explained in this article: Chinese industrial revolution. One of the points that is being made in this article is that China did not have access to colonies the way that the European countries did. You could argue that when Europe started colonizing the world, China was very capable of doing this as well, but for some reason never did.

The current COVID-19 pandemic suggests a mechanism. A sufficiently contagious and deadly pathogen could prevent larger groupings of people from forming stable societies. The recent large outbreaks of Ebola virus disease provide similar examples as population sizes grow, the possibility of severe epidemics increases.

Smaller groups would continue to survive in isolation, but any attempts at communication from larger gatherings or permanent habitation would result in an outbreak that would return the population back to the pre-industrial state.

This could be repeated until a form of remote communication with sufficient incentive to drive development could be managed as desired.

An alternative mechanism is a sufficiently complex solar system like the one in Jerry Pournelle's Janissaries where predictable, if unlikely, orbital mechanics trigger reversion back to a tribal society periodically.

If your world is governed by a religious regime which keeps the folk dumb and dismisses any technical progress and science as witchcraft, which gets destroyed and the creators are silenced.

Something similar Christianity did(on purpose or not) in the Middle Ages in Europe which is known as "the dark age of christianity". Some critics say, it delayed the technical progress of humanity for a few decades and as technical progress is growing exponentially, we would be now way more developed.

The Problem with this approach is that one day(eventually some millennia but most likley not) the people will succsessfully rise against the regime/religion and smash it what causes the end of your delay.

I do not think so unless there was some major things lacking in the world.

These are some points for why:

You could technically make a steam engine out of "precision" pottery and a good glaze the piston, wrist pin, connecting rod, and crank could all work like this using that glaze and some good lubricant to keep it all spinning happily. The piston would use a leather wrap to seal against the glazed cylinder walls. This is possible if you went to the extreme and said there were no hard metals on this earthlike planet.

Unless there was a complete lack of competition someone would want to get an edge on producing more of x cheaper than their competitors. This drives innovation which maybe were out clay steam engine is invented from. Would the people living in the information age on this planet call throwbacks to this era clay punk, pottery punk, ceramic punk, or glazed punk?

In a earthlike world any species that does not try to get a leg up will become evolutionarily irrelevant and eventually succumb to other individuals who compete for resources. Unfortunately this is why we can't have a proper star trek society yet.

conceivably the world could simply reject it as a taboo or religion but someone will eventually eat the apple and have a leg up on all the believers leading to more people peeling off from the herd and it will snowball from there.

you could have the intelligent species be unable to build or use tools as in no hands still could conceivably use mouths but you could always pull a page from the star control universe and make them similar to the slylandro.

Logistical barriers could prevent it.

You can power a factory with a waterwheel, and make some product by the millions, but if you cannot sell it by the millions you will not recoup your investment. You need either a huge nearby city or the ability to send your goods significant distances and still be cheaper than hand-made produce. And you won't see many huge cities that aren't trade hubs.

Rough seas can put a pretty hard damper on trade. If there aren't any large, fertile areas supporting enough people to justify a canal network, it might never be feasible to build a factory.

Iron is quite common because it is common byproduct of star development. Making iron scarce will mean your planet is lacking inner iron core, which creates magnetic field which prevent radiation to kill life on Earth. So on a planet with no magnetic core, life might not be possible. Or life would have be different (like: underwater only).

So if your intelligent life has to life under water, they would have hard time to get fire! Water surface would be outer edge of their world, and bigger obstacle for expansion than is stratosphere for us.

No, you can not

There are lot of things you can do to slow the advancement of technology, but every engineering problem has many solutions; so, taking away Option A only means you need a little longer to figure out how to meet your goal with Option B or C or D...

The only thing that can stop technological progress all together is not having a written language. As long as people can preserve their ideas and inventions for others to follow up on, technology just builds one discovery upon the next. But if you take away record keeping in all of its forms, then you make all knowledge volatile and harder to share with more than a few people. In this way you could get stuck in the stone age for millions of years as our ancestors did, or perhaps another pre-industrial period if your people are clever enough with oral traditions, but not clever enough to write things down.

However, any species like humans that is capable of abstract thought and driven to invent and share knowledge will eventually recognize their need to record that knowledge. Written language was independently invented in several places throughout the world whether it be pictographic, phonetic, or a system of knot tying. Even blind people have figured out braille; so, just making a simple change to human anatomy probably won't do it either.

The best you could do is put a hurdle in mankind's neurological makeup that simply makes writing an inconceivable notion, but even this will only be temporary at evolutionary time scales. Given enough time, a tool using species will be selectively more fit based on their capacity for abstract thinking. Selecting for abstract thought will push a species in the direction of being well adapted for literacy.

Avoid situations where labor is expensive

Epidemics, famine, flood, and other disasters may reduce the labor pool that people are looking for substitutes for it. The Black Death was particularly impressive in that it was continent-wide. Small disasters may be compensated for by having immigrants from more populous regions move in -- perhaps by plan. Which leads to another factor.

Avoid political fragmentation

There were steam engines and water wheels in the Roman Empire, but they were not put to massive use. The plentitude of slaves hindered that, but another issue was that they wanted to keep the slaves busy, and they did not have to worry about what another powerful nation would do with the machinery. Political fragmentation facilitates an industrial arms race.

Geography helps there. If the rich farmlands are joined by rivers or sea, so that transportation is easy, and the hinterlands are poor and do not support settlement, a unified government can arise and remain more easily. Then it will be more concerned about stability than competition.
