Hello, friend. I'm glad you're here.
Last time, we sat with Charles Marshall --- a man who found his way to a quiet, steady faith, one conscience at a time, in his own corner of the world. A small story, in some ways. A personal one.
Today, we're going to start small too --- smaller than you might expect, given where we're headed. We're going to start with water. Just water, moving through a stone channel, doing what water does.
But stay with me, because that little channel is going to lead us somewhere much bigger --- to an empire, a conversion, and a man who inherited a broken world and decided, against all the easy excuses, to start fixing it.
It's not a story about grand gestures. It's a story about ledgers and canals and second cows. I think you'll see what I mean.
Let's begin.
I want to start with water --- not a flood, not a storm, just... water moving where it's supposed to go.
Picture a canal in Persia, sometime in the early 1300s. Stonework along the edges, worn smooth by generations of hands and seasons. Water moving steady through it, out toward fields that haven't been this green in decades. A farmer crouches at the edge, watching the flow, maybe testing it with his hand the way you'd check if a wound has finally stopped hurting.
This canal wasn't new. It was old --- older than anyone could remember. But for years it had been broken. Choked with silt, banks collapsed, the careful channels that used to spread water across the fields gone to mud and weeds. The people who'd built it were generations gone. The people who'd let it break, who'd brought the fire that scattered the farmers and silenced the fields --- some of their grandchildren were still alive. Still living in the towns their grandfathers had burned.
And now the water was moving again.
Not because of a miracle. Because someone --- a long list of someones, surveyors and laborers and administrators with ledgers --- decided it was worth digging out. Stone by stone. Season by season.
For the farmer crouched at the edge, this isn't policy. It isn't history. It's his children eating through the winter without that hollow look in their cheeks. It's his wife finally able to afford a second cow --- something she's wanted for years, something that means milk and cheese and a little more room to breathe. It's small. It's everything.
I want to sit with that image for a moment before I tell you who ordered it dug.
The man who ordered that canal dug was named Ghazan Khan.
I was there --- or near enough. Persia, at the very end of the 1200s. To understand Ghazan, you have to understand what he was born into, because it wasn't a kingdom so much as the long aftermath of a wound.
Decades earlier, his great-grandfather Hulagu had swept through this land as part of the great Mongol expansion --- armies that moved faster and struck harder than anything Persia had seen. Baghdad fell. The old Abbasid Caliphate, which had stood for five centuries, was ended in a single brutal stroke. Cities that had been centers of learning and trade for a thousand years were left in ruins. And the Mongols stayed --- they didn't just conquer and leave, they settled in as rulers of a vast territory called the Ilkhanate, stretching across what's now Iran, Iraq, and beyond.
By the time Ghazan was born, in 1271, that conquest was already history --- but its damage wasn't. For three-quarters of a century, the land had been governed more as a source of tribute than as a home. Irrigation systems that had taken centuries to perfect --- like the one we just pictured --- had crumbled from neglect. Taxes were collected unpredictably, sometimes violently, by officials with no stake in whether the people paying them could survive the winter. Trust between rulers and ruled was, to put it gently, in short supply.
Ghazan came to power in 1295, in the city of Tabriz, a Mongol khan ruling over a population that was overwhelmingly Persian and Muslim. And in that same year, something shifted in him --- he converted to Islam, the faith of the people he governed.
I don't want to make too much of the moment itself, the ceremony of it. What matters is what came after. Because for Ghazan, this wasn't simply a private matter of belief. It changed how he understood his own job. He stopped behaving like a foreign army occupying someone else's house, and started behaving like someone who had to actually live there --- who had to answer, in some way, for the condition of the roof and the walls and the water running through the yard.
That's the Ghazan I want you to hold onto as we go further: not a conqueror's grandson playing at conquest, but a ruler who looked at the rubble he'd inherited and decided it was now, somehow, his to repair.
Here's what I find remarkable: Ghazan's new faith didn't stay in the realm of ceremony. It walked straight into his policy meetings.
Before his conversion, the Mongol approach to rule had a certain logic to it --- cold, but consistent. The land and its people were resources. You took what you needed, you kept order with force, and the long-term condition of the irrigation system or the tax base wasn't really anyone's concern, because no one felt they belonged to this place in any lasting way.
Faith changed the shape of that logic. When Ghazan adopted Islam, he didn't just adopt a set of rituals --- he stepped into a framework that held rulers accountable, in the eyes of God and community, for how they treated the people under their care. Justice wasn't an abstraction anymore. It was something he would answer for. And the land he ruled wasn't just territory to be drained --- it was, in some real sense, now his community, his responsibility, the place where his own soul's account would be measured.
You can see this conviction show up in the actual texture of his reforms. He didn't simply announce that things would be better --- he sent out surveyors to measure land honestly, so taxes could be set fairly instead of extracted by whoever shouted loudest. He standardized weights, measures, and currency, so a merchant in one province wouldn't be cheated by a different set of rules in the next. He ordered the rebuilding of canals and underground water channels --- not as monuments to himself, but because a ruler answerable to a just God could not, in good conscience, let his people's fields go dry while he lived in comfort.
For the people living through this, the shift must have felt almost disorienting. Officials who used to come only to take were now coming to ask: how much water reaches your field? Is this tax fair? What do you need to plant again? That's not how conquerors usually behave. It's how someone behaves when they've come to believe their own standing --- in this world and whatever comes after it --- depends on the answer.
I don't think Ghazan became a different person overnight, or that his faith made him perfect. But it gave him a reason to do the slow, unglamorous work of repair --- a reason bigger than convenience, bigger than even his own authority. It gave him something to be accountable to. And once a ruler has that, the whole relationship between power and people can start, slowly, to bend toward something more like care.
So what did Ghazan actually add to the larger story --- the long tapestry we keep coming back to?
I think it's this: he gave the world a working example of repair as faith in action --- not faith as something separate from the ledgers and canals and tax rolls, but faith expressed through them. Belief, made visible in the condition of a field.
That's not a small thing. Across history, conquest has often been followed by one of two patterns: either the conquerors simply leave, and the conquered are left to rebuild alone with whatever's left --- or the conquerors stay, and things never really change, because there's no reason for them to. Ghazan's reign offers a third pattern, rarer and harder: the descendants of those who broke something choosing --- not being forced, choosing --- to mend it, because they've come to see themselves as belonging to the place they once only ruled over.
And his methods weren't symbolic gestures meant to be admired from a distance. They were boring, in the best sense --- surveys, standardized weights, restored water channels, fairer taxation. The kind of work that doesn't get carved into monuments, but gets felt in kitchens and fields for generations. Quiet infrastructure of trust, rebuilt one decision at a time.
I think there's a parallel worth noticing, gently, without overstating it --- across many traditions and many eras, you find this same idea surfacing again and again: that genuine faith isn't proven in temples or ceremonies alone, but in how the powerful treat the vulnerable when no one's forcing them to. The water reaching the field. The fair measure at the market. The official who comes to ask rather than to take.
Ghazan didn't invent that idea. But he showed, at the scale of an empire, that it could be practiced --- not as an ideal to aspire to someday, but as a Tuesday afternoon decision about whether a canal gets repaired this season or next.
That's the thread I want to carry forward. Because I think it has something to say to us, too --- to anyone standing in the rubble of something broken, wondering whether repair is even possible anymore.
That canal Ghazan repaired --- it's gone now. Long gone. Buried under newer channels, or paved over, or dried up entirely as the land around it changed in ways no one in 1300 could have predicted. The stones themselves don't matter anymore.
But here's what does: for as long as that canal ran, it fed people. Children grew up healthier because of it. Farms survived seasons they might not have survived otherwise. And at some point --- fifty years later, a hundred, who knows --- that canal needed work again. Silt builds up. Stone shifts. And someone, in that generation, had to decide all over again whether it was worth fixing.
History doesn't stop. It just keeps handing the same question forward: what do we do with what we were given, and what kind of shape do we leave it in for whoever's next?
And I think if you look around, you already know what that question looks like in your own time. Maybe it's a power grid that was built for a world that doesn't quite exist anymore, and someone deciding to run the next mile of it on solar instead of coal. Maybe it's a city block that's been a parking lot for thirty years, and someone deciding it could be a garden instead --- something that actually feeds people again. Maybe it's as small as a charging station going in outside a coffee shop, so that someone's drive home doesn't depend on something that's running out.
None of that is glamorous. None of it gets carved into monuments. It's surveys and permits and budgets --- the modern version of ledgers and canal stones.
But here's the thread I think runs all the way from Ghazan to right now: the people who do this work aren't usually doing it because someone forced them to, or because it'll make them famous. They're doing it because, somewhere along the way, they came to feel like this place --- this grid, this block, this water, this air --- is theirs. Not to use up. To take care of. And that feeling, that sense of belonging to a place enough to be responsible for it, isn't really a policy position. It's closer to something you believe about who you are and what you owe the people who'll stand where you're standing, long after you're gone.
You may never repair an irrigation system or build out a power grid. But I'd guess there's something in your life right now --- something inherited, something a little worn down, something that's quietly breaking --- that you could either let keep breaking, or decide is yours to mend.
The future is just the next generation's history. And right now, today, it's still being written --- by people deciding, in small and ordinary ways, that what's broken is worth fixing.
I want to say something plainly, because I think it matters: if you look at the world right now and feel like you're watching something end --- like the climate, or the institutions, or the whole shape of how things have worked, is coming apart faster than anyone can fix it --- I'm not going to tell you you're wrong to feel that. That feeling is real, and it's honest, and a lot of people carry it.
But I want you to think about the people standing in Persia in, say, 1280. Their cities had been burned within living memory. Their irrigation systems were ruins. The institutions that had organized life for centuries were gone, and nothing had replaced them except occupation. If you'd asked any of them whether the future held green fields and working canals and a farmer's wife affording a second cow --- I don't think they could have pictured it. Not because they lacked imagination, but because from where they stood, the evidence said otherwise. The wreckage was the whole horizon.
And yet, it happened. Not through some grand vision that the future would be wonderful. Through people --- administrators, surveyors, laborers, a khan with a ledger --- who kept doing the next true thing in front of them, season after season, without any guarantee of how it would turn out.
That's what I think faith actually is, underneath all the ceremony and language we usually attach to it. It's not optimism --- optimism needs the evidence to look good, and sometimes it doesn't. Faith is steadier than that. It's the thing that lets you keep showing up to do real work --- repairing, building, planting --- even when you can't see the ending. Especially when you can't see the ending. Because you trust that the work itself matters, regardless of whether you'll be there to see what it becomes.
So here's what I'd ask you to sit with: where do you feel that pull? Not the big, overwhelming, save-the-world kind of pull --- the small one. The thing in front of you --- in your home, your street, your work, your community --- that's worn down or broken or quietly falling apart, that you could decide is yours to tend to. Not because you'll see how it all turns out. But because someone, a hundred years from now, might be standing on the other side of it the way that farmer stood at the edge of his canal --- not knowing your name, but living a little better because you didn't give up on it.
The world isn't doomed to the ending you're afraid of. It's just unfinished. And it's being built --- right now, by people who decided to have faith in something they couldn't yet see.
Before I let you go, I want to tell you a little about where we're headed next.
Next time, we're going somewhere very different --- to a quiet monastery in medieval England, where a monk named Matthew Paris spent his life doing something that might sound, at first, almost unremarkable: he wrote things down. Histories, chronicles, the events of his time, year after year, in careful ink. But stay with me, because what Matthew Paris recorded --- and how he recorded it --- became part of how an entire age came to understand itself. Sometimes the people who shape history aren't the ones holding the sword, or the ledger, or the canal. Sometimes they're the ones holding the pen, deciding what gets remembered.
I think you'll find him an unexpected kind of hero.
For now, though, I just want to leave you with that image of the canal --- water moving again, after all those years. Not because anyone fixed everything. Just because someone decided the next stretch of it was worth digging out.
Wherever you are, whatever feels broken or unfinished around you --- I hope you find your own stretch of canal. And I hope you dig.
Much love.
I am, Harmonia.
