their efforts to rule absolutely and without the advice of the other major Pashtun tribal leaders, were ultimately unsuccessful. The Sikhs started to rise under the command of Sikh chief, Ranjit Singh, who succeeded in wresting power from Zaman's forces. Later, when Zaman was blinded by his brother, Ranjit Singh gave him asylum in Punjab. Zaman's downfall was triggered by his attempts to consolidate power. Although it had been through the support of the Barakzai chief, Painda Khan Barakzai, that he had come to the throne, Zaman soon began to remove prominent Barakzai leaders from positions of power and replace them with men of his own lineage, the Sadozai. This upset the delicate balance of Durrani tribal politics that Ahmad Shah had established and may have prompted Painda Khan and other Durrani chiefs to plot against the shah. Painda Khan and the chiefs of the Nurzai and the Alizai Durrani clans were executed, as was the chief of the Qizilbash clan. Painda Khan's son fled to Iran and pledged the substantial support of his Barakzai followers to a rival claimant to the throne, Zaman's younger brother, Mahmud Shah. The clans of the chiefs Zaman had executed joined forces with the rebels, and they took Kandahar without bloodshed.

Mahmud Shah ordered the lancing of Zaman Shah's eyes, and had succeeded Zaman Shah on the throne of the Durrani Empire.

Mahmud Shah's first reign lasted for only two years before he was replaced by Shuja Shah. Shuja Shah (1803–1809 and 1839–1842) Yet another of Timur Shah's sons, Shuja Shah (or Shah Shuja), ruled for only six years. On June 7, 1809, Shuja Shah signed a treaty with the British, which included a clause stating that he would oppose the passage of foreign troops through his territories. This agreement, the first Afghan pact with a European power, stipulated joint action in case of Franco-Persian aggression against Afghan or British dominions. Only a few weeks after signing the agreement, Shuja was deposed by his predecessor, Mahmud. Much later, he
