Ghalib (Urdu: غاؔلِب), born Mirza Asadullah Baig Khan (Urdu: مِرزا اسَدُاللہ بیگ خان), (27 December 1797 – 15 February 1869), was a prominent Urdu and Persian poet during the last years of the Mughal Empire. He used his pen-names of Ghalib (Urdu: غالِب, ġhālib means "dominant") and Asad (Urdu: اسَد, Asad means "lion"). His honorific was Dabir-ul-Mulk, Najm-ud-Daula. During his lifetime, the already declining Mughal empire was eclipsed and displaced by the Colonial British Raj and finally deposed following the defeat of the Indian rebellion of 1857, are some of the events that he described through his work.
Most notably, he wrote in both Urdu and Persian. His Persian Divan is at least five times longer than his Urdu but his fame rests on his poetry in Urdu.
