How did Russian and British rivalry shape the Wakhan Corridor?

The Wakhan Corridor was shaped by the Great Game, a 19th-century geopolitical rivalry between the British Empire and Russia for control over Central Asia.1

As Russia expanded into Central Asian khanates, British representatives sought to establish a clear physiographic boundary to protect British India from potential Russian encroachment. Following a confrontation between tsarist and British forces at Bozai Gombaz in 1891, the two empires negotiated to settle political control of the region.2

To prevent direct contact between their respective territories, they established the Wakhan Corridor as a neutral buffer zone. This thin strip of land, which extends to the Chinese border and separates present-day Tajikistan from the northern portion of Kashmir, was formally incorporated into Afghanistan as part of the broader effort to delineate spheres of influence.12
