Why was Xi’an the eastern terminus of the Silk Road?

Xi’an (historically known as Chang’an) served as the eastern terminus of the Silk Road primarily due to its strategic geography and its status as a major political and economic center.

Located in the Wei River valley, the city functioned as a natural transportation hub where the primary east-west route from the North China Plain connected to the Hexi Corridor and the western steppelands. Because it was the capital for several powerful dynasties—most notably the Han, Sui, and Tang—the city possessed the immense wealth and infrastructure necessary to support large-scale international trade.123

Furthermore, its location in the Guanzhong region made it easily defensible and critically important as a frontier post for interacting with neighboring principalities. This combination of being a secure, prosperous imperial capital and a central junction for diverse regional routes established it as the essential gateway for the exchange of goods, religions, and ideas between China and the West.2314
