Passage: Ghalib (Urdu: غاؔلِب‎), born Mirza Asadullah Baig Khan  (Urdu: مِرزااسَدُاللہ 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, events that he described. Most notably, he wrote several ghazals during his life, which have since been interpreted and sung in many different ways by different people. Ghalib, the last great poet of the Mughal Era, is considered to be one of the most famous and influential poet of the Urdu and Persian languages. Today Ghalib remains popular not only in India and Pakistan but also among the Hindustani diaspora around the world.
