Ramani Gabharu (c.1656 – c.1684) was a princess of Kingdom of Assam and the first wife of titular Mughal emperor Muhammad Azam Shah.
She was sent to the Mughal Emperor as part of the Treaty of Ghilajharighat at the age of seven and was renamed Rahmat Banu Begum after she married Muhammad Azam Shah.
[2] She was the maternal granddaughter of Momai Tamuli Borbarua, an able administrator and the commander-in-chief of the army in the Ahom kingdom, and the niece of Lachit Borphukan and Laluksola Borphukan,[3] known for their participation in the Battle of Saraighat that thwarted a drawn-out attempt by Mughal forces under the command of Ram Singh I to take back Kamrup.
Even after being defeated in the hands of Lachit Bagphukanas, Ram Singh I spoke highly of the manifold qualities of the Ahom Soldiers.
When Ramani Gabharu learned of it, she wrote a letter to her maternal uncle Laluksola Borphukan warning him not to do such an act of betrayal.
