John Philip Walker Lindh is an American Taliban member who was captured by United States forces as an enemy combatant during the United States' invasion of Afghanistan in November 2001. He was detained at Qala-i-Jangi fortress, used as a prison. He denied participating in the Battle of Qala-i-Jangi, a violent uprising of the Taliban prisoners, stating that he was wounded in the leg and hid in the cellar of the Pink House, in the southern half of the fort. He was one of the 86 prisoners who survived the uprising, from an estimated 400 prisoners in total. CIA officer Johnny "Mike" Spann was killed during that uprising. Brought to trial in United States federal court in February 2002, Lindh accepted a plea bargain; he pleaded guilty to two charges and was sentenced to 20 years in prison. He was released on supervision on May 23, 2019, for a three-year period of supervised release.

The Taliban, which also refers to itself by its state name, the Islamic Emirate of Afghanistan, is an Afghan militant movement with an ideology comprising elements of Pashtun nationalism and the Deobandi current of Islamic fundamentalism. It ruled approximately three-quarters of the country from 1996 to 2001, before being overthrown following the American invasion. It recaptured Kabul on 15 August 2021 following the departure of most coalition forces, after nearly 20 years of insurgency, and currently controls all of the country. Its government is not recognized by any country. The Taliban government has been internationally condemned for restricting human rights in Afghanistan, including the right of women and girls to work and to have an education.
