Background: Mirza Basheer-ud-Din Mahmood was born to Ghulam Ahmad and Nusrat Jahan Begum on 12 January 1889 in Qadian, the same year in which Ghulam Ahmad established the Ahmadiyya Movement by accepting allegiance from his disciples. Due to chronic illness Mahmood Ahmad was unable to attend to secondary education. During his youth, he remained an active member in the service of the Movement by founding a journal entitled Tash'heezul Az'haan and accompanied his father on many of his journeys. On 26 May 1908, Ghulam Ahmad died in Lahore when Mahmood Ahmad was 19 years old.
Context: In 1931 the All India Kashmir Committee was set up for the establishment of the civil rights of the Muslims of Kashmir and to alleviate their oppression. Mahmood Ahmad was elected its first president. He sought to gather Muslim leaders with different opinions on one platform and strive unitedly for the cause of the Muslims of Kashmir. He is known to have achieved great success in doing so. The committee turned the attention of the Muslims of Kashmir towards acquiring education and Mahmood Ahmad himself gave practical help towards this cause. It also encouraged trade, commerce and involvement in politics among the Muslims of Kashmir.  The committee however faced strong opposition from the Indian National Congress and the Ahrari campaign against the Ahmadiyya. The Ahrar alleged that the formation of the committee took place by the Ahmadiyya in order to spread its teachings and strongly opposed the leadership of Mahmood Ahmad. In an address to a gathering in 1931 Mahmood advised the Ahrar's thus:  I admonish the Ahrari's that if there is any among them present here, they should go and tell their friends! I care not in the least about these stones and for this reason am not angered with them. They should stop this hearsay for the sake of the oppressed brothers of Kashmir. Let them come; I am ready to leave presidency but they must promise that they will follow the decision of the majority of Muslims. Today we have seen their morals, let them come and see our morals too. I assure them that even after stepping down from presidency, me and my community shall help them (the people of Kashmir) more than their associates. Presidency is not a thing of respect for me. Respect is gained from service. The leader of a nation is one who serves it ...  Mahmood Ahmad resigned from presidency in 1932 due to the agitations of the Ahrar party.
