Siraj ud-Daulah received the title of "Mansur-ul-Mulk, Seraj-ud-Daulla, Ghaseti Begum"(Victory of the Country, Light of the State, Horror in War). He was to succeed as the Nawab of Bengal in April 1756 AD at the age of twenty seven. Siraj ud-Daulah's nomination to the nawabship caused jealousy and enmity of "Mehar-un-nisa Begum" or "Ghaseti Begum"(eldest sister of Siraj's Mother Amina Begum), Raja Rajballabh, Mir Jafar Ali Khan and "Shaukat Jang"(Siraj's Cousin). Ghaseti Begum possessed huge wealth, which was the source of her influence and strength. On Perceiving serious opposition from her, Siraj ud-Daulah seized her wealth from Moti Jheel Palace and placed her in confinement. The "nawab" also made certain changes in high government positions giving them to his own favorites.
