A closed desert basin ringed by the Kunlun, Pamir, and Tianshan ranges. Oases around the basin’s edge create isolated pockets of settlement, each tied to mountain snowmelt. The Tarim’s geography forces civilization into small, trade-oriented city-states — Kashgar, Khotan, Turpan — linked to the Silk Road and shaped by constant movement of goods, languages, and empires. Harsh interior deserts prevent large-scale unity, making this region the classic frontier between China, Iran, and the steppe.
