The War in Afghanistan was a conflict that took place from 2001 to 2021 in Afghanistan.[72] It started when the United States and its allies invaded Afghanistan[73] and toppled the Taliban-ruled Islamic Emirate.[74][75] The war ended with the Taliban regaining power after a 19 years and 8 months insurgency[76] against allied NATO and Afghan Armed Forces.[77][78][79][35] It was the longest war in United States history, surpassing the Vietnam War (1955–1975) by roughly five months.
