The Northern Alliance, officially known as the United Islamic National Front for the Salvation of Afghanistan, was a military alliance of groups that operated between early 1992 and 2001 following the dissolution of the Soviet Union. 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. Defectors such as Rashid Dostum and Abdul Momim allied with Ahmad Shah Massoud and Ali Mazari forming the Northern Alliance. 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 Islamic Emirate of Afghanistan's (Taliban) takeover of Kabul, The United Front was reassembled.

Ahmad Shah Massoud was an Afghan military leader and politician. He was a powerful guerrilla commander during the resistance against the Soviet occupation during the Soviet–Afghan War from 1979 to 1989. In the 1990s, he led the government's military wing against rival militias; after the Taliban takeover, he was the leading opposition commander against their regime until his assassination in 2001.
