The War in Afghanistan began on 7 October 2001, about a month after the 9/11 attacks on the United States. It ended on 30 August 2021, when the last American troops left the country. At almost 20 years, it was the longest war the United States ever fought.
Why did the war in Afghanistan start?
After the 9/11 attacks in 2001, the United States demanded that Afghanistan's Taliban rulers hand over Osama bin Laden, the leader of al-Qaeda. When the Taliban refused, the U.S. and its allies attacked to remove them from power and destroy al-Qaeda's safe base.
Which countries fought in the War in Afghanistan?
The war began with the United States, Britain, and Afghan groups fighting the Taliban and al-Qaeda. Over time, NATO and about 40 more countries joined, including Canada, Australia, Germany, France, Italy, and many others.

Operation Enduring Freedom was the name of the U.S.-led campaign that began on 7 October 2001. American and British forces, helped by Afghan fighters on the ground, quickly removed the Taliban government and hunted for al-Qaeda leaders.

The Taliban were a strict Islamic movement that ruled most of Afghanistan from 1996 to 2001. They sheltered al-Qaeda before 9/11, were removed from power by the U.S.-led invasion, fought as rebels for 20 years, and took back control of the country in 2021.
