Nawab Mohsin-ul-Mulk, Munir Nawaz Jang, also known as Syed Mir Mehdi Ali (Urdu: نواب محسن الملک، منیر نواز جنگ، سید مہدی علی) (born 9 December 1837 – 16 October 1907), was an Indian Muslim politician.

He was a close friend of Syed Ahmed Khan, was involved in the Aligarh Movement and was one of the founders of the All India Muslim League in 1906.

For his meritorious service for more than a decade, he was granted the titles of Munir Nawaz Jang in 1884 and Nawab Mohsin-ul-Mulk in 1887, by the Nizam of Hyderabad.

[3][1] Mohsin-ul-Mulk converted to Sunnism despite being born a Shia and authored the book Ayat-i Bayanat in which he showed why the Sunni faith was preferable.

[2] This meeting resulted in a long lasting companionship and Nawab Mohsinul Mulk became a staunch supporter of Syed's vision and mission for the rest of his life.

He appointed a committee under the Chairmanship of Maulana Habibur Rahman Khan Sherwani to improve the religious studies courses at MAO College.

[1] Nawab Mohsin-ul-Mulk carried on correspondence with the private secretary of the Viceroy to give his point of view on the necessity of separate representation for the Muslims in all legislatures and local bodies.

He presided over the ninth session of Muhammadan Educational Conference which was held in Aligarh in 1894 where he proposed a resolution to help and support Darul Uloom Nadwatul Ulama, the newly formed religious school in Lucknow.

[7] Syed Ahmed Khan and Nawab Mohsin-ul-Mulk's patronage of Urdu led to its widespread use amongst elite Indian Muslim communities and following the Partition of India its adoption as the national language of Pakistan.

[7][9] Mohsin-ul-Mulk died from chronic diabetes at age 69 on 16 October 1907 at Simla, Punjab, British India.
