Roshanara's relationship with her older sister, Jahanara, was troubled and tinged by jealousy, as the latter was undisputedly their father's favourite daughter. Roshanara scored a major victory against her sister when Aurangazeb, who had been displeased with Jahanara for supporting their father and brother during the war of succession, removed her (Jahanara) from her position as Padshah Begum and head of the Imperial harem, installing Roshanara, in her stead. From then on, Roshanara was regarded as the most powerful and superior woman in the empire. she was also granted the right to issue "farmans" and "nishans". This exceptional privilege was allowed only to those who held the best and highest rank in the imperial harem. She was appointed as a Mansabdar, a high ranking position in the Emperor's army that was used to enforce his rule and maintain his authority, especially during his absence.
