Mirza Basheer-ud-Din Mahmood Ahmad (Urdu: مرزا بشیر الدین محمود احمد)(born January 12, 1889 in Qadian; died November 7, 1965 in Rabwah), was the second caliph of the Ahmadiyya Muslim Community and the eldest son of Mirza Ghulam Ahmad from his second wife. He was given the title of Khalifatul Masih II. He was elected to this office at the young age of 25 on 14 March 1914, the day after the death of his predecessor, Hakim Noor-ud-Din.
Migration to Pakistan
In 1947 following the partition of India and the creation of Pakistan, He carefully oversaw the emigration of members of the community from Qadian to Pakistan. He kept 313 men known as Dervishes in Qadian to guard the sites holy to Ahmadis, including two of his sons. Initially the Community settled at Lahore and it wasn't until 1948 that the Community found a tract of arid land and built the town of Rabwah under the leadership of the Khalifa. Rabwah swiftly developed into the Community's new headquarters. In the newly found nation, Mahmood Ahmad delivered a series of lectures on the future of Pakistan in terms of:
* Defence
* Agriculture and industry
* Forestation
* Livestock and mineral assets
* Economic growth
* Development of land air and naval forces.
