Mirza Nasir-ud-Din Muḥammad Shah (born Roshan Akhtar; 7 August 1702 – 26 April 1748) was the 13th Mughal emperor, who reigned from 1719 to 1748. He was son of Khujista Akhtar, the fourth son of Bahadur Shah I. After being chosen by the Sayyid Brothers of Barha, he ascended the throne at the young age of 16, under their strict supervision. He later got rid of them with the help of Asaf Jah I – Syed Hussain Ali Khan was murdered at Fatehpur Sikri in 1720 and Syed Hassan Ali Khan Barha was fatally poisoned in 1722. Muhammad Shah was a great patron of the arts, including musical, cultural and administrative developments. His pen-name was Sadā Rangīla (Ever Joyous) and he is often referred to as "Muhammad Shah Rangila", also sometimes as "Bahadur Shah Rangila" after his grand father Bahadur Shah I.
