"The Great Game" is a term used by historians to describe a political and diplomatic confrontation that existed for most of the nineteenth century between Britain and Russia over Afghanistan and neighbouring territories in Central and Southern Asia. Russia was fearful of British commercial and military inroads into Central Asia, and Britain was fearful of Russia adding "the jewel in the crown", India, to the vast empire that Russia was building in Asia. This resulted in an atmosphere of distrust and the constant threat of war between the two empires.
