The national flag of the Islamic Emirate of Afghanistan was adopted on 15 August 2021, with the Taliban's victory in the 2001–2021 war. It features a white field with a black Shahada inscribed. The white stands for "the (Islamic Movement of Taliban's) purity of faith and government"; the flag incorporated the shahada, the Islamic declaration of faith, after 1997. This current Afghan flag likely was inspired by the historic Umayyad caliphate, which began the Muslim conquest of the Indian subcontinent, the Ghazwa-e-Hind: Islam entered Afghanistan with the Umayyad invasion, begun in 663–665 A.D. It is still used to represent Afghanistan at the Olympic Games and other international sporting events.
Afghanistan has had 27 different national flags since the 18th century.
Afghanistan got its current name in 1919, when the nation won its independence from the United Kingdom. The name Afghānistān means "land of the Afghans", which originates from the ethnonym Afghan. The last part of the name, -stān is a Persian suffix for "place".
Historically, the name Afghan mainly designated Pashtuns, the largest ethnic group of Afghanistan. Pashtuns are an Iranian ethnic group constituting around 48% of the country's total population.
Some modern scholars suggest that the word "Afghan" is derived from words awajan/apajan in Avestan and ava-han/apa-han in Sanskrit, which means "killing, striking, throwing and resisting, or defending." Under the Sasanians, and possibly the Parthian Empire, the word was used to refer to men of a certain Persian sect.
