Much of Peshawar's caravan trade from Kabul ceased on account of skirmishes between Afghan and Sikh forces, as well as a punitive tax levied on merchants by Ranjit Singh's forces. Singh's government also required Peshawar to forfeit much of its leftover agricultural output to the Sikhs as tribute, while agriculture was further decimated by a collapse of the dried fruit market in north India. Singh appointed Neapolitan mercenary Paolo Avitabile as administrator of Peshawar, who is remembered for having unleashed a reign of terror. His time in Peshawar is known as a time of "gallows and gibbets." The city's famous Mahabat Khan, built in 1630 in the Jeweler's Bazaar, was badly damaged and desecrated by the Sikh conquerors.
