According to many scholars, the New Persian language (which subsequently evolved into the Persian forms spoken in Iran, Afghanistan and Tajikistan) developed in
Transoxiana and
Khorasan, in what are today parts of Afghanistan, Iran,
Uzbekistan and Tajikistan. While the New Persian language was descended primarily from
Middle Persian, it also incorporated substantial elements of other
Iranian languages of ancient Central Asia, such as
Sogdian. Following the
Islamic conquest of Iran and most of Central Asia in the 8th century AD,
Arabic for a time became the court language and
Persian and other Iranian languages were relegated to the private sphere. In the 9th century AD, following the rise of the
Samanids, whose state was centered around the cities of
Bukhoro (
Buxoro),
Samarqand and
Herat and covered much of Uzbekistan, Tajikistan, Afghanistan and northeastern Iran, New Persian emerged as the court language and swiftly displaced Arabic. New Persian became the lingua franca of Central Asia for centuries, although it eventually lost ground to the
Chaghatai language in much of its former domains as a growing number of
Turkic tribes moved into the region from the east. Since the 16th century AD, Tajik has come under increasing pressure from neighbouring
Turkic languages. Once spoken in areas of
Turkmenistan, such as
Merv, Tajik is today virtually non-existent in that country.
Uzbek has also largely replaced Tajik in most areas of modern Uzbekistan – the
Russian Empire in particular implemented
Turkification among Tajiks in Ferghana and Samarqand, replacing the dominant language in those areas with Uzbek. Nevertheless, Tajik persisted in pockets, notably in Samarqand, Bukhoro and
Surxondaryo Region, as well as in much of what is today Tajikistan. The creation of the
Tajik Soviet Socialist Republic within the
Soviet Union in 1929 helped to safeguard the future of Tajik, as it became an official language of the republic alongside
Russian. Still, substantial numbers of Tajik speakers remained outside the borders of the republic, mostly in the neighbouring
Uzbek Soviet Socialist Republic, which created a source of tension between
Tajiks and
Uzbeks. Neither Samarqand nor Bukhoro was included in the nascent Tajik SSR, despite their immense historical importance in Tajik history. After the creation of the Tajik SSR, a large number of ethnic Tajiks from the Uzbek SSR migrated there, particularly to the region of the capital,
Dushanbe, exercising a substantial influence in the republic's political, cultural and economic life. The influence of this influx of ethnic Tajik immigrants from the Uzbek SSR is most prominently manifested in the fact that literary Tajik is based on their northwestern dialects of the language, rather than the central dialects that are spoken by the natives in the Dushanbe region and adjacent areas. After the fall of the Soviet Union and Tajikistan's independence in 1991, the government of Tajikistan has made substantial efforts to promote the use of Tajik in all spheres of public and private life. Tajik is gaining ground among the once-
Russified upper classes and continues its role as the vernacular of the majority of the country's population. There has been a rise in the number of Tajik publications. Increasing contact with media from Iran and Afghanistan, after decades of isolation under the Soviets, as well as governmental orientation toward a "Persianisation" of the language have brought closer Tajik and the other Persian dialects. ==See also==
