Ghaseti Begum was the eldest daughter of Nawab Alivardi Khan, the Nawab of Bengal, and Princess Sharfunnisa, the paternal aunt of Mir Jafar. Her paternal grandfather was Mirza Muhammad Madani, who was of either Arab or Turkic descent, the son of a foster-brother of the Mughal emperor Aurangzeb.[2][3] Her paternal grandmother belonged to the Turkic Afshar tribe of Khorasan. Through her, she was a relative of Shuja-ud-Din Muhammad Khan, the two having shared a common ancestor in Nawab Aqil Khan.[2][4]
After the death of Nawab Alivardi Khan, Ghaseti Begum tried to enthrone Shaukat Jang, the son of her second sister Maimuna Begum.[1] But Siraj ud-Daulah managed to ascend to the power of Bengal. Eventually she secretly conspired against him with the help of Mir Jafar, the chief of Alivardi Khan's army, along with the merchants Omichund and Jagat Seth.[citation needed]
Death
After the fall of Siraj ud-Daulah in the Battle of Plassey in 1757, Ghaseti was imprisoned in the Jinjira Palace by Mir Jafar. But sensing danger, Miran, son of Mir Jafar, moved Ghaseti to Murshidabad in 1760.[5] She was believed to have been drowned in the Buriganga River on the way by order of Miran.[6]
