Nawab Mohammad Ismail Khan (1884–1958) was an eminent Muslim politician and a leading activist of the All-India Muslim League, who stood in the forefront of the Khilafat Movement and Pakistan Movement. Nawab Mohammad Ismail Khan is regarded as one of the founding fathers of the Islamic Republic of Pakistan due to the roles that he fulfilled for the cause of it. His position was described as only second to that of Muhammad Ali Jinnah. This is also evident through the letters that were actively exchanged between the leaders. After the creation of Pakistan, he decisively chose to remain in India.
