Afghan (also referred to as Afghanistani) (Pashto/Persian: افغان; see: etymology) refers to someone or something from Afghanistan, in particular a citizen of that country. Prior to the rise of the nation as Afghanistan, it was used by Persian speakers and those influenced by the Persian language to denote the Pashtun people. In modern times, Afghan is rarely used as an ethnic term for the Pashtuns, but is rather used as the national demonym for all citizens of Afghanistan—Pashtuns, and a large number of Tajiks, Hazaras, Uzbeks, Aimaqs, Turkmens, Balochs, Nuristanis, Pashayis, Pamiris, Arabs, and others. According to the Encyclopædia Iranica, the word Afghan (afḡān) in current political usage means any citizen of Afghanistan, regardless of their tribal or religious affiliation. According to the 1964 Constitution of Afghanistan, all Afghans are equal in rights and obligations before the law. The fourth article of the current Constitution of Afghanistan states that citizens of Afghanistan consist of Pashtun, Tajik, Hazara, Uzbek, Turkmen, Aimaq, Arab, Baluch, Pashayi, Nuristani, Qizilbash, Gurjar, Brahui, and members of other tribes. As an adjective, the word Afghan also means 'of or relating to Afghanistan or its people, language, or culture'. The term 'Afghani' refers to the unit of Afghan currency. The term is also often used (and appears in some dictionaries) for a person or thing related to Afghanistan, although some have expressed the opinion that this usage is incorrect. The term 'Afghani' (or more usually 'al-Afghani') is also a common surname among Afghans – for example, Jamāl al-Dīn al-Afghānī and Jamila Afghani. The Afghani currency unit was created in 1925. Between 1925 and 1993 varieties of Afghani coins and banknotes were in circulation through Afghanistan. Coins issued during this period consisted of: 1, 2, 3, 5, 10, 20, 25 pul in bronze, brass, copper nickel, and aluminum-bronze; silver ½, 1, and 2½ Afghani; and gold ½, 1, and 2½ amani. Banknotes issued were in: 2, 5, 10, 20, 50, 100, 500, 1,000, 5,000, and 10,000 Afghani. In 1958 bank notes worth 2 and 5 were switched with coins.
