The Islamic Emirate of Afghanistan (Pashto: د افغانستان اسلامي امارت, romanized: Da Afghānistān Islāmī Imārāt), retroactively referred to as the First Islamic Emirate of Afghanistan, was a totalitarian Islamic state led by the Taliban that ruled most of Afghanistan from 1996 to 2001. At its peak, the Taliban government controlled approximately 90% of the country, while remaining regions in the northeast were held by the Northern Alliance, which maintained broad international recognition as a continuation of the Islamic State of Afghanistan. The Taliban referred to the government as interim throughout the entire period of its existence, despite the strong and permanent role of Mullah Omar in the government.
After the September 11 attacks and subsequent declaration of a "war on terror" by the United States, international opposition to the regime drastically increased, with diplomatic recognition from the United Arab Emirates and Pakistan being rescinded. The Islamic Emirate ceased to exist on 7 December 2001 after being overthrown by the Northern Alliance, which had been bolstered by the ISAF coalition established after a U.S.-led invasion of the country two months prior. The Taliban continued to refer to itself as the Islamic Emirate of Afghanistan in official communications when it was out of power from 2001 to 2021.
