Durrani Invasions
In 1749, Ahmad Shah Abdali invaded India in order to avenge his defeat earlier on. Thus Mueen-ul-Mulk gathered his force and also sent messages to Delhi for assistance. However, he soon found out that his foe's army was bigger and better than his. In addition, the Mughal Emperor had not given any support. Thus he offered peace to Ahmad Shah, who immediately accepted it. Under the terms of the treaty, Mueen-ul-Mulk gave the invader 5 million rupees and had some Durrani regiments escorted to Lahore. He did this primarily in fear of an attack from the imperial forces, since he had made peace without Delhi's consent. His fears soon justified when the Mughal Emperor sent Shahnawaz Khan to replace Mueen-ul-Mulk At this time Mir Bakshi Imad-ul-Mulk the eldest son of Asaf Jah I decided to stake his claim for the Deccan and goaded the emperor to issue a firman proclaiming him Subedar of Deccan. Imad-ul-Mulk then entered into a conspiracy with the Marathas against his younger brother Salabat Jung. However while at Deccan Imad-ul-Mulk died under suspicious circumstances. At Delhi his son Imad-ul-Mulk very cunningly came into prominence and wreaked havoc at the court for the next five years.
