<P> In 1703, Prince Azim - us - Shan, the grandson of Mughal Emperor Aurangzeb came as the Governor of Pataliputra . Azim - us - Shan, renamed Pataliputra as Azimabad, in 1704 . Khan Zaman Khan Ali Asghar ibn Qazi Ghulam Mustafa was later on appointed as Naib Subahdar by Farrukhsiyar at Azimabad . </P> <P> Eventually, the name Azimabad fell out of use, and was replaced by Patna, the name Sher Shah Suri opted to call this ancient city . Patna is the most common way of referring to Bihar's capital city from colonial period onward . Nevertheless, there is a New Azimabad Colony inside Patna today named after Patna that is primarily inhabited by Muslims who were inspired by Patna's Mughal name . Similarly, Pataliputra is understood as part of the modern city Patna, not the whole city itself . Thus, to some extent, while the name "Patna" has replaced and to some extent engulfed Azimabad and Pataliputra, the legacy of these former names during the ancient and early modern exists and will continue to persist for the foreseeable future . </P>

Who change the name of patna to azimabad
