Mahmoud Ahmadinejad was born in village of Aradan near city of Garmsar, southeast of Tehran in 1956. He is the fourth son of an ironworker who had seven children. Mahmoud and his family migrated to Tehran when he was one-year-old. He went to primary and high school in Tehran and got his diploma and was admitted to the University of Science and Technology (Elm-o-Sanaat) in the field of civil engineering after he ranked 132nd in the nationwide university entrance exams in 1975. He was accepted as an MS student at the same university in 1986 and became a member of the scientific board of the Civil Engineering College of University of Science and Technology. Later on he got his doctorate in 1987 in the field of engineering and traffic transportation planning. He is married with two sons and one daughter.
Following the 1979 Islamic revolution he became a member the conservative faction of the Office for Strengthening Unity [OSU] Between Universities and Theological Seminaries. The OSU was established by Ayatollah Mohammad Beheshti, one of Ayatollah Khomeini's key advisors, to organize Islamic students against the rapidly growing Islamic group of Mojahedin-e Khalq (MEK).
With invasion of Iraq and start of the Iran-Iraq war in 1980, Ahmadinejad rushed to the western fronts to fight against the enemy and joined the voluntary (basij) forces of the Islamic Revolution's Guards Corps (IRGC). He served in different units of the Islamic Revolution Guards Engineering Corps.
He served as governor of Maku and Khoy cities in the northwestern West Azerbaijan province, and as an advisor to the governor general of the western province of Kurdistan for two years. While serving as the cultural advisor to then Ministry of Culture and Higher Education in 1993, he was appointed as governor general of the newly established northwestern province of Ardebil from 1993 to 1997. He was elected as the exemplary governor general for three consecutive years. But in 1997 the newly-installed Khatami administration removed Ahmadinejad from his post as Ardebil governor general. He returned to the University of Science and Technology (Elm-o-Sanaat) again to teach in 1997.
In April 2003 Ahmadinejad was appointed mayor of Tehran by the capital's municipal council, which is dominated by the hard-line Islamic Iran Developers Coalition (Etelaf-e Abadgaran-e Iran-e Islami). In some of Ahmadinejad's public statements, he has appeared to identify himself as a Developer. He lives a very Spartan lifestyle and that's how he projected himself. As Mayor, he reversed many of the policies of previous moderate and reformist mayors, placing serious religious emphasis on the activities of the cultural centers by turning them into prayer halls during the Islamic holy month of Ramadan. He also suggested the burial of the bodies of martyrs of the Iran-Iraq war in major city squares of Tehran.
On 24 June 2005 Dr. Mahmoud Ahmadinejad was elected as Iran's sixth president. He swept to the presidential post with a stunning 17,046,441 votes out of a total of 27,536,069 votes cast in the runoff election.
In the 2009 presidential election Ahmadinejad was nominated to run for the second term.
In the presidential election of 2009, 39,165,191 ballots were cast on 12th June, according to Iran's election headquarters. Ahmadinejad won 24,527,516 votes, (62.63%). In second place, Mir Hossein Mousavi won 13,216,411 (33.75%) of the votes. The election drew unprecedented public interest in Iran.
The election results remain in dispute as Mir Hossein Mousavi and his supporters who believe that electoral fraud occurred during the election. This popular belief ignited protests and demonstrations in the large cities with a united slogan of “Where is my vote”, which resulted in the birth of “Green Movement” of Iran.
Finally Supreme Leader Ayatollah Ali Khamenei formally endorsed Ahmadinejad as President on 3 August 2009, and Dr. Ahmadinejad was sworn in for a second term on 5 August 2009.
