The Second Anglo-Afghan War was waged between the British Raj and the Emirate of Afghanistan from 1878 to 1880. A consequence of the Great Game between Britain and Russia, the conflict was instigated by the latter sending an uninvited diplomatic mission to Kabul, despite the wishes and protestations of Sher Ali Khan, the Amir of Afghanistan. When a British demand for their own diplomatic mission was refused, the Second Anglo-Afghan War commenced. The first phase of the invasion saw a string of British military victories that led to the Treaty of Gandamak, which saw Afghan foreign affairs given over to the British in exchange for internal sovereignty and military protection; British representatives were installed in Kabul to secure the deal. When the representatives were slaughtered by an uprising in 1879 however, the second phase of the war began, which once again saw the British reigning supreme and the ceding of further territories from Afghanistan.
