The Forsyth expedition to Central Asia was one of the most important, at least politically speaking, to have been carried out up to that point. It provided considerable information about the region borders of China, Russia, and British India. The key details the numerous explorations of the area throughout the 1860s and 1870s.
Forsyth's embassy to Yarkand took place several years before the Second Anglo-Afghan War (1878) and some twenty years before the Pamir Boundary Commission protocols brought "The Great Game" to an end by establishing the Russo-Afghan border.
The Great Game is a term used to describe the confrontation between the British and Russian Empires over territory in Central Asia. The region was seen as an integral buffer zone by both Britain and Russia; for the British, Russian control of Central Asia posed a risk of invasion to British India; whereas the Russians were eager to combat the expansion of the British Empire from India up to the southern border of the Russian Empire.
Although largely forgotten by history today, the Pamir Plateau was the focal point of one of the great geopolitical showdowns of the late 19th century.
