Cause

The February 2020 US–Taliban deal triggered a US military withdrawal and removal of technical and logistical support that Afghan security forces depended upon. Compounding factors included ghost soldiers, unpaid salaries, cronyism in military appointments, police extortion, and President Ghani's failure to build a national consensus among warlords and ethnic communities.

Event

Beginning 1 May 2021, the Taliban launched a sweeping offensive across Afghanistan, rapidly expanding district control from 73 to 223 within three months. By 13 August, major cities including Herat, Kandahar, and Lashkargah had fallen. On 15 August, President Ghani fled the country and the Taliban captured Kabul with minimal resistance, collapsing the Islamic Republic of Afghanistan.

Consequence

The Islamic Emirate of Afghanistan was reinstated as the de facto governing authority. The swift collapse surprised the United States, allied governments, Russia, and even the Taliban itself. Widespread international concern followed over human rights conditions under Taliban rule and the potential for Afghanistan to again become a base for terrorist organizations.
