Uzbek Emir of Bukhara agreed that the Amu Darya would mark the division of their lands. Ahmad Shah retired to his home in the mountains east of Kandahar, where he died in 1772. He had succeeded to a remarkable degree in balancing tribal alliances and hostilities, and in directing tribal energies away from rebellion. He earned recognition as Ahmad Shah Baba, or "Father" of Afghanistan. The Durrani Empire lost its control over Kashmir to the Sikh Empire in the Battle of Shopian in 1819. Other Durrani rulers in the Empire (1772–1823) Ahmad Shah's successors governed so ineptly during a period of profound unrest that within fifty years of his death, the Durrani empire per se was at an end, and Afghanistan was embroiled in civil war. Much of the territory conquered by Ahmad Shah fell to others in this half century. By 1818, the Sadozai rulers who succeeded Ahmad Shah controlled little more than Kabul and the surrounding territory within a 160-kilometer radius. They not only lost the outlying territories but also alienated other tribes and lineages among the Durrani Pashtuns. Humayun Mirza (1772) A few months before his death, Ahmad Shah summoned Timur Shah from Herat and publicly declared him heir to the Durrani Empire. Ahmad Shah made this decision without consulting with his tribal council, as a result the authority of the Durrani Emperor was put into question and created a growing rift that would toil the Durrani empire for years to come, as the tribal council had in majority, supported Ahmad Shah's eldest son and Timur Shah's brother, Sulaiman, the governor of Kandahar. Prominent figures in court who supported the Sulaiman faction were Shah Wali Khan, Ahmad Shah's Wazir, and Sardar Jahan Khan. The court had attempted to urge Ahmad Shah to reconsider his decision, coinciding with the fact that the eldest son should ascend to the throne. Ahmad had ignored this, and quoted: "Timur Shah was infinitely more capable of governing you than his brother". As well as accusing Sulaiman of being "Violent without clemency", and out of favour with the Kandahari Durranis. Ahmad Shah's decision could have been influenced by his illness, which had affected his brain and his mental state. However, choosing Timur Shah as a successor was likely to restrict power of the Senior Generals and the Durrani Tribal Council, which he deemed as a threat to his dynasty in the future. When
