Mohammed Fahim (Afghan: Tajik فهيم, also known as "Marshal Fahim"; 1957 – 9 March 2014) was an Afghan military commander, politician and the Vice President of Afghanistan from November 2009 until his death in March 2014. He was the Defense Minister of the Afghan Transitional Administration, beginning in 2002 and also served as Vice President from June 2002 to December 2004. Marshal Fahim was replaced by Abdul Rahim Wardak, who was appointed as Defense Minister by President Hamid Karzai on 23 December 2004 when the transitional administration gave way to a popularly-elected administration. Fahim returned to government however, after Karzai named him as candidate for Vice-President during his re-election campaign. Marshal Fahim was a member of Afghanistan's Tajik ethnic group. He was the recipient of the Ahmad Shah Baba Medal. He was fluent in Dari, Pashto and Arabic, but did not speak English. He was affiliated with Jamiat Islami (Shura-e Nazar) party of Afghanistan.
Fahim was born in Omarz in the Panjshir Province of Afghanistan, the son of Abdul Matin from the Panjshir Valley. Ahmad Shah Masood. He became Masoods deputy in military affairs and the commander of the Mujahideen in the northern sector. When the pro-Soviet regime in Kabul collapesed in 1992, Fahim was appointed head of the KHAD, under interim president Sibghatullah Mojaddedi. He continued to serve as the country's head of intelligence under president Burhanuddin Rabbani. (Bhatia, 2007; Brown & Oliver, 2001)
He is reported to have finished his studies in Islamic Sharia at an Arabic institute in Kabul in 1977. Some sources have allegedly claimed that Fahim served as a member of the KHAD during the 1980s, although the most reports indicate that he has been fighting the communist rulers since the late 70s. He is said to have fled Afghanistan after the Communist coup of 1978, he became a refugee in Peshawar. One year later, he returned to Panjshir and began to work under Commander
In 1996, Fahim also personally offered to evacuate former Communist President Mohammad Najibullah, then in custody in Kabul, from the advancing Taliban forces, but Najibullah refused to be evacuated and was captured and executed by a Taliban mob. General Fahim continued to serve as Head of the Intelligence and Minister of National Security of the internationally recognised United National Front Government, even when the Taliban took the power over most provinces of Afghanistan in the second half of the 90s.
The new government of Afghanistan was officially inaugurated on 22 December. Fahim who became Defence Minister as well as one of the five vice-chairman was considered one of the young and moderate leaders of the new Afghan government. As general commander of the mujahideen resistance forces, he proclaimed an offensive on the northern and western fronts on 7 October, in the wake of building pressure of the US against the Taliban regime.
Fahim was confirmed as the defence minister of the Northern Alliance, succeeding Ahmad Shah Massoud and thereby the new leader of the forces of the Northern Alliance. Massoud, Afghanistan's most important resistance leader, had been assassinated two days earlier on 9 September 2001 by al-Qaeda operatives posing as journalists. Fahim was a close ally and protégé of Massoud.
On 12 September 2003, Miloon Kothari, appointed by the United Nations Commission on Human Rights to investigate housing rights in Afghanistan, announced that many of the government ministers including Fahim and Education Minister Yunus Qanuni were illegally occupying land and should be removed from their posts. However, three days later, Kothari sent a letter to Lakhdar Brahimi, the head of the UN in Afghanistan, saying he had gone too far in naming the ministers. Some Afghan analysts attest that, despite losing his military position, Marshal Fahim still remains a very powerful figure in the political arena of the country. In 2006, Karzai, faced with a resurgent Taliban, returned Marshal Fahim to Government as an advisor.
Fahim died of a heart attack on 9 March 2014. The government of Afghanistan called for a three-day national mourning period.
