He was Born on December 23, 1940 at Agra in British India, Mamnoon Hussain, the President of the Islamic Republic of Pakistan.
He migrated to Pakistan in 1949 with his entire family.
Graduating in commerce (Hons.) from Karachi University in 1963, he joined the Institute of Business Administration (IBA), Karachi to do Master in business Administration in 1965.
He joined Muslim League in Karachi and soon became Joint Secretary of the City Organization. He entered the national politics by joining Pakistan Muslim League (N) in 1993. In view of his integrity and commitment, he was appointed the Finance Secretary of the PML (N), Sindh. In 2001, he was given the portfolio of the General Secretary of the PML (N), Sindh, and he continued in that office until 2005. His formidable stature as a veteran politician earned him the honour of the Acting President of the PML (N), Sindh. In recognition of his meritorious services for his party, he was appointed Senior Vice President (SVP) of the PML (N) and Member of the Central Executive Committee in 2005. In 1997-98, he was appointed Advisor to the Chief Minister of Sindh. In 1999, he was elected to the coveted position of the President of the Karachi Chamber of Commerce & Industry (KCCI).
In June 1999, he went on to become the Governor of Sindh, but his term was cut short on October 12, 1999 when the PML (N) government was removed. His credentials as a politician devoted to the cause of democracy were established when he became a political prisoner after raising his voice against the totalitarian regime of the then military dictator.
In landslide victory, Mr. Mamnoon Hussain was elected as the 12th President of Pakistan through his official nomination made by PML (N). He took the oath of office on September 09, 2013. Since he has a firm belief that the office of the President of Pakistan is a symbol of Federation and should be apolitical, therefore, he has resigned from the PML (N).
