At the beginning of his rule, the Afghans lost their former stronghold of Peshawar Valley in March 1823 to the Sikh Khalsa Army of Ranjit Singh at the Battle of Nowshera. The Afghan forces in the battle were led by Azim Khan, half-brother of Dost Mohammad Khan.[10] By the end of his reign, he had reunited the principalities of Kandahar and Herat with Kabul. Dost had ruled for a lengthy 36 years, a span exceeded only by Zahir Shah more than a century later.
The Musahiban family started with his older brother, Sultan Mohammad Khan, nicknamed "Telai", meaning "golden", a nickname he was given because of his love of fine clothing.[11]
