early 19th century by the Persians in the west and the Sikhs in the east. The western provinces of Khorasan and Kohistan were taken by the Persians in 1800. Fateh Khan, leader of the Barakzai tribe, had installed 21 of his brothers in positions of power throughout the empire. After his death, they rebelled and divided up the provinces of the empire between themselves. During this turbulent period, Afghanistan had many temporary rulers until Dost Mohammad Khan declared himself emir in 1826. The Punjab region was lost to Ranjit Singh, who invaded Khyber Pakhtunkhwa and in 1834 captured the city of Peshawar. In 1837, Akbar Khan and the Afghan army crossed the Khyber Pass to defeat the Sikhs at the Battle of Jamrud, killing Hari Singh Nalwa before retreating to Kabul. By this time the British were advancing from the east and the First Anglo-Afghan War, one of the first major conflicts during the Great Game, was initiated.

Following the 1842 Battle of Gandamak that was fought between Akbar Khan and William Elphinstone, the British established diplomatic relations with the Afghan government but withdrew all forces from the country. They returned during the Second Anglo-Afghan War in the late 1870s for about two year military operations, which was to defeat Ayub Khan and assist Abdur Rahman Khan establish authority. The United Kingdom began to exercise a great deal of influence after this and even controlled the state's foreign policy. In 1893, Mortimer Durand made Amir Abdur Rahman Khan sign a controversial agreement in which the ethnic Pashtun and Baloch territories were divided by the Durand Line. This was a standard divide and rule policy of the British and would lead to strained relations, especially with the later new state of Pakistan.
