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.

Mohammad Najibullah Ahmadzai, commonly known as Dr. Najib, was an Afghan politician who served as the General Secretary of the People's Democratic Party of Afghanistan, the leader of the one-party ruling Republic of Afghanistan from 1986 to 1992 and as well as the President of Afghanistan from 1987 until his resignation in April 1992, shortly after which the mujahideen took over Kabul. After a failed attempt to flee to India, Najibullah remained in Kabul. He lived in the United Nations headquarters until his assassination during the Taliban's capture of Kabul.
