Afghanistan is a multiethnic society. The population of the country is divided into a wide variety of ethnolinguistic groups. The ethnic groups of the country are as follow: Pashtun, Tajik, Hazara, Uzbek, Aimak, Turkmen, Baloch, Pashai, Nuristani, Gujjar, Arab, Brahui, Pamiri and some others. The Afghan National Anthem mentions a total of 14 ethnic groups.
The term "Afghan" is synonymous with the ethnonym "Pashtun" and has been mentioned as early as the 3rd century, referring to the tribes inhabiting the lands south of the Hindu Kush around the Sulaiman Mountains. It became prominent during the Khilji, Lodi, and Suri dynasties of Northern India. The name became the national identity of Afghanistan in modern times. Despite being of various ethnic groups, in a research poll that was conducted in 2009, 72% of the population labelled their identity as Afghan first, before ethnicity.
