Ghalib was the prominent Urdu and Persian-language poet during the last years of the Mughal Empire. He used his pen-names of Ghalib (means "dominant") and Asad (means "lion"). His honorific was Dabir-ul-Mulk, Najm-ud-Daula.
During his lifetime the Mughals were eclipsed and displaced by the British 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 popular and influential poets of the Urdu language. Today Ghalib remains popular not only in India and Pakistan but also among the Hindustani diaspora around the world.
