Routes, and the towns that taxed them
How places with nothing to sell got rich on other people's cargo.
What does a place actually need in order to profit from trade it does not produce?
What you should be able to do after this: Identify the recurring requirements of an entrepôt — a chokepoint or transfer point, water and supplies, security, and neutrality enough for rivals to use it — and see why that advantage is never permanent.

- Samarkand · Geographic contextStop 1 · Samarkand · Central AsiaAn oasis is a decisionWhy a city in a desert became one of the busiest places in Asia.0 of 4 chapters read · about 10 min
Samarkand's advantage was water in an arid corridor: a caravan route is a chain of places where you can drink. Follow the corridor east to the valley the routes are named from.
- Xi'an · Geographic contextStop 2 · Xi'an · East AsiaThe valley that kept being the capitalChang'an, the Wei river, and the eastern end of the overland routes.0 of 4 chapters read · about 9 min
Chang'an was a capital as well as a terminus, which changes the incentives — it wanted to control the route, not just profit from it. Now cross to a transfer point with no empire behind it at all.
- Timbuktu · Geographic contextStop 3 · Timbuktu · AfricaWhere the river meets the desertA port for camels, and a city that measured its wealth in manuscripts.0 of 4 chapters read · about 10 min
Timbuktu shows the same logic on a desert edge instead of a mountain one, and adds something the others share: where goods move, texts and ideas move on the same animals. Venice made that its whole business model.
- Stop 4 · Venice · EuropeA city that chose the waterWhy a lagoon was safer than land, and what that costs now.0 of 4 chapters read · about 9 min
Venice · AI city illustrationVenice lost its advantage when a sea route opened that did not pass through it. Singapore is the modern version of the same bet — and is still, so far, winning it.
