Mullah Omar in the context of "Taliban"

The war in Afghanistan was a prolonged armed conflict lasting from 2001 to 2021. It began with an invasion by a United States–led coalition under the name Operation Enduring Freedom in response to the September 11 attacks carried out by the Taliban-allied and Afghanistan-based al-Qaeda. The Taliban were expelled from major population centers by American-led forces supporting the anti-Taliban Northern Alliance, thus toppling the Taliban-ruled Islamic Emirate. Three years later, the American-sponsored Islamic Republic was established, but by then the Taliban, led by founder Mullah Omar, had reorganized and begun an insurgency against the Afghan government and coalition forces. The conflict ended almost twenty years later as the 2021 Taliban offensive reestablished the Islamic Emirate. It was the longest war in United States military history, surpassing the Vietnam War by six months.

Following the September 11 attacks, masterminded by al-Qaeda leader Osama bin Laden, American president George W. Bush demanded that the Taliban immediately extradite him to the United States and close down al-Qaeda's camps in Afghanistan; the Taliban refused and demanded evidence of bin Laden's guilt before offering to hand him over to a neutral country. The U.S. dismissed these offers and proceeded with the invasion. After expelling the Taliban and their allies, the American-led coalition remained in Afghanistan, forming the International Security Assistance Force (ISAF)—sanctioned by the United Nations—with the goal of creating a new democratic authority in the country that would prevent the Taliban from returning to power. A new Afghan Interim Administration was established, and international rebuilding efforts were launched. By 2003, the Taliban had reorganized and launched a widespread insurgency against the new Afghan government and coalition forces. Insurgents from the Taliban and other Islamist groups waged asymmetric warfare, fighting with guerrilla warfare in the countryside, suicide attacks

An Islamic state has a form of government based on sharia. As a term, it has been used to describe various historical polities and theories of governance in the Islamic world. As a translation of the Arabic term dawlah islāmiyyah (Arabic: دولة إسلامية) it refers to a modern notion associated with political Islam (Islamism). Notable historical examples include the first Islamic state in Medina, established by the prophet Muhammad, and the Arab caliphates which continued under his successors, such as the Rashidun and Umayyads.

The concept of the modern Islamic state has been articulated and promoted by ideologues such as Rashid Rida, Mullah Omar, Abul A'la Maududi, Ruhollah Khomeini, Israr Ahmed, Sayyid Qutb and Hassan al-Banna. Implementation of Islamic law plays an important role in modern theories of the Islamic state, as it did in classical Islamic political theories. However, most of the modern theories also make use of notions that did not exist before the modern era.

The Buddhas of Bamiyan (Pashto: د باميانو بودايي پژۍ, Dari: تندیس‌های بودا در بامیان) were two monumental Buddhist Reliefs in the Bamiyan Valley of Afghanistan, carved possibly around the 6th-century. Located 130 kilometres (81 mi) to the northwest of Kabul, at an elevation of 2,500 metres (8,200 ft), carbon dating of the structural components of the Buddhas has determined that the smaller 38 m (125 ft) "Eastern Buddha" was built around 570 CE, and the larger 55 m (180 ft) "Western Buddha" was built around 618 CE, which would date both to the time when the Hephthalites ruled the region.

In March 2001, both structures were destroyed by the Taliban following an order given on February 26, 2001, by Taliban leader Mullah Muhammad Omar, to destroy all the statues in Afghanistan "so that no one can worship or respect them in the future". International and local opinion condemned the destruction of the Buddhas.

The supreme leader of Afghanistan (Pashto: د افغانستان مشر, romanized: Də Afġānistān Məshar, Dari: رهبر افغانستان, romanized: Rahbar-i Afghānistān), officially the supreme leader of the Islamic Emirate of Afghanistan and also referred to by his religious title Amir al-Mu'minin (Arabic, lit. 'Commander of the Faithful'), is the absolute ruler, head of state, and national religious leader of Afghanistan, as well as the leader of the Taliban. The supreme leader wields unlimited authority and is the ultimate source of all law.

The first supreme leader, Mullah Omar, ruled Afghanistan from 1996 to 2001 before his government was overthrown by the United States and he was forced into exile. The current supreme leader is Hibatullah Akhundzada, who assumed office in exile during the Taliban insurgency on 25 May 2016, upon being chosen by the Leadership Council, and came to power on 15 August 2021 with the Taliban's victory over Afghan government forces in 2021. Since coming to power, Akhundzada has issued numerous decrees that have profoundly reshaped government and daily life in Afghanistan by implementing his strict interpretation of the Hanafi school of Sharia law.
