What is Dari? Afghanistan’s Persian and Its Origins

Dari is the variety of Persian spoken in Afghanistan, also known as Eastern Persian or Afghan Persian. It shares its historical roots with Iranian Persian and Tajik, while its name has older associations with court speech and the New Persian literary language.

If you follow the name backward, you reach a court, a spoken language and a literary tradition that extended beyond today’s Afghanistan. The route runs through post-Sasanian Khorasan, Persian literature under the Samanids and Ghaznavids, and Afghanistan’s decision to make the name official in 1964.

Which language did early sources call Dari?

The earliest meanings of Dari were broader than its modern official use in Afghanistan. An account attributed to Ibn al-Muqaffa describes it as the speech of the cities of Mada’in and the ruler’s court. The association is with a court environment, rather than with the borders of modern Afghanistan.

Gilbert Lazard derives the name from the Persian word dar. It means ‘door’ and can also refer to a palace. This explanation connects the language’s name with the same court setting described in the account attributed to Ibn al-Muqaffa.

Dari also named a spoken language. Al-Jahiz used the term in that sense in the middle of the ninth century. His usage matters because the name later appears prominently in discussions of literary Persian. Its history includes speech as well as writing.

From the tenth century onward, Arabic and Persian texts used Dari for the New Persian literary language. When you encounter Dari in such a text, the word therefore needs its historical context. It can refer to a literary language whose reach exceeded the modern Afghan use of the name.

A particularly concrete example comes from the physician Maysari. In his Danishnama, dated 978–981, he called the language in which he wrote Dari. Here, the term appears as a writer’s own description of his language.

How did New Persian develop in post-Sasanian Khorasan?

Ludwig Paul dates the Early New Persian period approximately to the eighth through twelfth centuries.

Paul describes the passage from Middle Persian to New Persian as a gradual development lasting more than 200 years. That timescale matters. The fall of the Sasanian state and the development of New Persian belong to connected histories, but they cannot be compressed into a single moment of linguistic change.

In Paul’s account, the Islamization of Khorasan provided the setting in which late Sasanian spoken Dari developed into New Persian written in Arabic letters. The explanation brings together a spoken inheritance, a changing regional setting and a written form.

Scholars have differed over how Dari reached Khorasan. Parviz Khanlari proposed that it had been the official administrative language of the Sasanian court. He argued that officials carried it eastward to Khorasan.

Lazard challenged that account. He identified Pahlavi as the Sasanian official written language and argued that Dari spread eastward as speech. The distinction concerns how the language travelled and what role it held within Sasanian administration.

Court patronage then supported Persian literary production. During the ninth and tenth centuries, the Samanid court at Bukhara encouraged Persian poetry. It also supported translations of Arabic works on history and science into Persian. New Persian thus served several kinds of writing.

The Ghaznavids, who ruled from 977 to 1186, continued this literary patronage in their territories in Afghanistan and northern India. Their support extended the tradition cultivated under the Samanids. The history of Afghanistan’s Persian therefore connects with a literary world spanning several regions.

What historical connections link Dari, Iranian Persian and Tajik?

Dari, Iranian Persian and Tajik continue a shared historical language lineage developed from Sasanian Middle Persian. Their relationship is visible in both formal writing and regional speech. The comparison changes depending on which of those you examine.

There is very little difference between the official written Persian of Afghanistan and Iran. The exceptions include some vocabulary and preferences in calligraphy. Formal writing therefore shows considerable continuity across the two countries.

Spoken Kabul Persian presents a different comparison. In pronunciation and some features of syntax, it is closer to Central Asian Tajik than to colloquial Iranian Persian. If you compare only official written texts, you miss this part of the relationship.

Regional connections also cross state borders. The Persian dialects of Herat share features with neighbouring dialects in Iranian Khorasan. Those of Badakhshan share features with neighbouring dialects in southern Tajikistan. These examples give the shared history a local geography.

Indiana University explains Tajik’s differentiation from Iranian Persian through political borders, geographical separation, standardization, and influences from Russian and Turkic languages. The modern distinctions thus reflect several historical processes within the broader Persian lineage.

Names and scripts add another layer. Tajiks historically called their language zaboni forsi. Soviet authorities popularized zaboni tojiki during the twentieth century. Tajik in Tajikistan uses Cyrillic, while the Dari used by Tajiks in Afghanistan uses the Perso-Arabic script.

Why was Dari adopted as an official language name in Afghanistan in 1964?

Article 3 of Afghanistan’s 1964 constitution designated Pashto and Dari as official languages. This was a constitutional adoption of a name with a long history. Dari had already appeared in accounts of speech and in descriptions of literary Persian centuries earlier.

Saloumeh Gholami interprets the official adoption as an effort to distinguish Afghanistan’s Persian from the varieties associated with Iran and Tajikistan. Under this reading, the choice gave a shared linguistic inheritance a specifically Afghan official designation.

Rawan Farhadi emphasizes a related historical claim. He explains the revival of the old name as an attempt to present Afghanistan as the language’s cradle. This is an interpretation of the purpose behind the naming decision.

Research in Law and History Review stresses the political dimension. It argues that choosing Dari helped distance Afghan Persian from identification with the national identity of modern Iran. Together, these interpretations explain why an old language name mattered to a modern state.

The constitution also distinguished between official status and national-language development. Although Article 3 named two official languages, Article 35 identified only Pashto as the national language whose development should be promoted. The wording placed the two languages in different constitutional roles.

Details you won’t find in guidebooks

An everyday word makes one sound distinction tangible. In Kabul Persian, shir with the vowel written î means milk, while sher with ê means lion: shîr and shêr. Kabul Persian preserves a vowel distinction that has merged in standard Iranian Persian. You can connect that historical difference to something as ordinary as milk.

Literary preferences also followed different regional paths. The Indian Persian poet Bidil lived from 1644 to 1720. His works became models in Afghanistan, while he remained little known in Iran. A shared literary language could sustain different choices of admired writers.

Dari also has an everyday public role in Afghanistan. It serves as a common language of communication among different ethnic groups and as the language of Persian-language media. Its history therefore connects court speech and literary patronage with ordinary communication.
