At the start of the 19th century, the Indian subcontinent was ruled in part by independent princely states and in part by the company rule of the British East India Company. During the 19th century a political and diplomatic confrontation developed between Britain and Russia over Afghanistan which later became known as "The Great Game". 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. If Russia were to gain control of the Emirate of Afghanistan, it might then be used as a staging post for a Russian invasion of India.
