Presidency of Hamid Karzai in the context of "Northern Alliance"

The Northern Alliance, officially known as the National United Islamic Front for the Salvation of Afghanistan, was an Afghan military alliance of groups that operated between early 1992 and 2001 following the dissolution of the Soviet Union. It was formed by military leaders such as Ahmad Shah Massoud, Burhanuddin Rabbani, Abdul Rashid Dostum, Abdul Momim and Ali Mazari. It consisted mainly of ethnicities from northern Afghanistan, such as Tajiks, Uzbeks, Hazaras, and Turkmens, as opposed to the Pashtun-led Taliban. At that time, many non-Pashtun Northerners originally with the Republic of Afghanistan led by Mohammad Najibullah became disaffected with Pashtun Khalqist Afghan Army officers holding control over non-Pashtun militias in the North. The alliance's capture of Mazar-i-Sharif and more importantly the supplies kept there crippled the Afghan military and began the end of Najibullah's government. Following the collapse of Najibullah's government, the Alliance would fall with a second civil war breaking out. However, following the Taliban's takeover of Kabul and establishment of their Islamic Emirate of Afghanistan, the United Front was reassembled.

The Northern Alliance fought a defensive war against the Taliban regime. They received support from Iran, Russia, Tajikistan, Turkmenistan, the United States and Uzbekistan, while the Taliban were extensively backed by the Pakistan Army and Pakistan's Inter-Services Intelligence. By 2001, the Northern Alliance controlled less than 10% of the country, cornered in the north-east and based in Badakhshan province. The US invaded Afghanistan, providing support to Northern Alliance troops on the ground in a two-month war against the Taliban, which they won in December 2001. With the Taliban forced from control of the country, the Northern Alliance was dissolved as members and parties supported the new Afghan Interim Administration, with some members later becoming part of the Karzai administration.
