Wuwei China, Silk Road

Wuwei, once known as Liangzhou, was the eastern end of the Hexi Corridor and played an important role in the history of the Silk Road. Settled over 5,000 years ago, the area was initially used as grazing land by the Yuezhi people during the Qin Dynasty. By the Han Dynasty, however, the Xiongnu tribe had taken control. It expelled the Yuezhi people, marking a turbulent time in the Corridor's history. 

In 121 BCE, Emperor Wu of Han tasked his 20-year-old nephew, General Huo Qubing, to lead an army against the Xiongnu. He achieved a decisive victory at the Battle of Mobei and helped secure the Hexi Corridor for the Han Dynasty. 

The Hexi Corridor itself is a long, narrow band of land stretching about 620mi (1,000km) through western Gansu Province. It is bordered by the imposing Qilian Mountains to the south and the arid expanse of the Tengger Desert to the north, making it an ideal route for connecting central China to the West and offering a safe passage through what would otherwise be tough terrain. Wuwei's location is particularly significant because it sits at the meeting point of three major geographical regions: the high-altitude Qinghai-Tibet Plateau, the fertile but erosion-prone Loess Plateau, and the arid Mongolian-Xinjiang Plateau. This unique convergence of landscapes shaped Wuwei's environment, contributing to its importance as a trade and cultural hub.

The Qilian Mountains were a lifeline for the region. Their snowy peaks not only created a natural protective barrier but also supplied vital water from melting snow, feeding rivers and streams, making farming and settlement possible in an otherwise dry region. Meanwhile, the Tengger Desert bounded the northern part of the corridor. Its harsh, dry conditions meant that travellers were forced to stick to the narrow strip of the Hexi Corridor, where resources were concentrated, and survival was more feasible. 

Wuwei's strategic position along the Hexi Corridor made safeguarding the Han Empire's western frontier essential. By controlling this vital region, the Han Dynasty could protect trade routes, monitor military movements, and maintain stability between central China and the nomadic tribes of the West.
