Mirza Asadullah Baig Khan (; 27 December 1797 – 15 February 1869), also known by the pen names of Ghalib () and Asad (), was an Indian poet. His honorific was "Dabir-ul-Mulk, Najm-ud-Daula". During his lifetime, the already declining Mughal empire was eclipsed and displaced by the British East India Company Rule and finally deposed following the defeat of the First Indian War of Independence (Sepoy Mutiny) of 1857; these are described through his work.
