On 15 August 2021, Afghanistan's capital city of Kabul was captured by the Taliban after a major insurgent offensive that began in May 2021. It was the final action of the War in Afghanistan, and marked a total victory for the Taliban. This led to the overthrowing of the Islamic Republic of Afghanistan under President Ashraf Ghani and the reinstatement of the Islamic Emirate of Afghanistan under the control of the Taliban.
