Safavid power with its distinctive Persian-Shi'i culture, however, remained a middle ground between its two mighty Turkish neighbors. The Safavid state, which lasted at least until 1722, was essentially a "Turkish" dynasty, with Azeri Turkish (Azerbaijan being the family's home base) as the language of the rulers and the court as well as the Qizilbash military establishment. Shah Ismail wrote poetry in Turkish. The administration nevertheless was Persian, and the Persian language was the vehicle of diplomatic correspondence (insha'), of belles-lettres (adab), and of history (tarikh)
The Azeri Turks are Shiʿites and were founders of the Safavid dynasty.
Адари (=азери) утрачивает позиции более быстрыми темпами, чем раньше, так что даже Сефевиды, первоначально ираноязычный клан (как свидетельствует четверостишия шейха Саафи-эль-Дина, их эпонимного предка, и его биография), тюркизировались и приняли тюркский язык в качестве родного. // In this period, under the Qara Qoyunlū and Āq Qoyunlū Turkmen (780—874/1378-1469 and 874—908/1469-1502 respectively), Āḏarī lost ground at a faster pace than before, so that even the Safavids, originally an Iranian-speaking clan (as evidenced by the quatrains of Shaikh Ṣafī-al-dīn, their eponymous ancestor, and by his biography), became Turkified and adopted Turkish as their vernacular.
В XVI веке, тюркоязычная семья Сефевидов из Ардебиля в Азербайджане, вероятно, тюркизированного иранского (возможно, курдского), происхождения, завоевала Иран и утвердила тюркский в качестве языка суда и армии, так он ввиду своего высокого статуса и широкого контакта с местными языками повлиял на разговорный персидский; в то время как письменный персидский, язык высокой литературы и гражданской администрации, остаётся в практически неизменном состоянии. // In the 16th century, the Turcophone Safavid family of Ardabil in Azerbaijan, probably of Turkicized Iranian (perhaps Kurdish), origin, conquered Iran and established Turkic, the language of the court and the military, as a high-status vernacular and a widespread contact language, influencing spoken Persian, while written Persian, the language of high literature and civil administration, remained virtually unaffected in status and content.
