Let’s start with this little video of the geographical spread of China over time.
Looks like the Han conquered a lot of other people. They then imposed their culture, their writing, and over time, their language on those people.
Here’s the rule: Any people who get a significant military advantage, use it to conquer. They may not do so immediately, but eventually they do so.
The Mongols conquered the largest land empire in history. They were undefeated for generations; absolutely crushing military advantage.
The Russians, later, with the gunpowder advantage, conquered their large land empire.
The gunpowder advantage was big, but not that big. It worked in the Americas because of a plague that killed off over 90 percent of the population. Absent that, at worst/best you have a situation closer to India, though probably with a bit more successful colonization.
In ancient history, the Greeks had a huge military advantage. They knew they had it for a while before it was used by Alexander to conquer a huge swathe of the ancient world. (This is similar to the Mongols’ horse-archer advantage; they had to wait for a Genghis Khan to use it effectively.)
Shaka would have done something similar, had he been born a thousand years earlier, but he had the bad luck to run into the Brits, who posessed a much larger advantage.
We know nothing about the Druids because the Romans slaughtered them, colonized most of their lands, and made the Gauls into semi-Romans. The Christians later finished the job.
The Norse are gone because they lost a multi-century religious war against the Christians. We have weird ideas about the Norse: They were reacting to a hegemonic religious ideology that was already force-converting pagans. Charlemagne (a profoundly evil man) forced Saxons to convert, then killed them. Figured he was saving their souls, no doubt.
So the Norse built a wall across the south of Denmark (being outnumbered) and took to the seas, where they had an advantage. They raided and destroyed monasteries not just because that’s where the loot was, but because it was Christianity driving the forced conversions.
The Norse, despite their “terror,” lost. The last Norse pagans, in Iceland, converted because if they didn’t, they would have lost the ensuing war.
The industrial revolution probably created the greatest military advantage the world has ever known. It was used to conquer most of the world that was still agrarian, and where it didn’t conquer, it humiliated. The second the Japanese industrialized, they went on their own conquering spree. Mao, unifying China, immediately conquered Tibet (ironically using a claim based on the notion that, “The Mongols conquered you and us at the same time, so you should be ours.”)
Again, the rule here is simple. People are people. When a group gets a massive military advantage, they use it to conquer and colonize (Greek colonies in the ancient world were endemic.) The larger the advantage, the more conquests. In time, conquests that are unsustainable go away, and those that have largely eradicated the indigenous culture (sometimes through genocide, sometimes by just getting rid of the culture), remain, even if nominally independent. Canada, Mexico, and even most South American countries are NOT resurgences of the people who ruled the countries before Europeans showed up. Neither are most of the areas China conquered in its millenia long march.
What China is doing in Tibet and to the Uighurs, in that light, is simply a modern version of what the Chinese have done for ages.
None of this means that colonialism and conquest and cultural or actual genocide are good. They aren’t.
They are, however, our current pattern. We are living through a holding pattern right now, to an extent, only because of nuclear weapons. If a massive advantage is obtained which neutralized nukes, this pattern would re-emerge.
If we want this pattern to end, we need to figure out why it happens: What creates the enabling conditions, and we need to become a conscious world civilization.
Right now, if you look at the “greenhouse gas” curve or at the “species extinction curve” and compare it to the curve of a bunch of bacteria in a petri dish growing uncontrollably until they die in their own waste, you won’t see any significant difference.
At the civilization and cultural level, we are not conscious. We do not make choices, much as we think we do. Instead we act like any other animal, driven by unconscious impulses and drives we apparently cannot control.
None of the evils we inflict, as societies, on each other or on the other species of the world, will cease for any significant amount of time, if we do not become conscious and work to change these behaviours.
If we can’t, we will likely go extinct. If not this time around, then next. We will keep careening into absolutely forseeable problems and doing nothing about them until its too late, and one of these days, it will kill us.
