In Iran, the Persian word for Azerbaijani is borrowed as Torki 'Turkic'. Iranian Azerbaijani, or Persian Azerbaijani, is widely spoken in Iranian Azerbaijan (historic Azerbaijan) and, to a lesser extent, in neighboring regions of Turkey and Iraq, with smaller communities in Syria. In 1853, Azerbaijani became a compulsory language for students of all backgrounds in all of Transcaucasia with the exception of the Tiflis Governorate. Beginning in 1834, it was introduced as a language of study in Kutaisi instead of Armenian. Per the 1829 Caucasus School Statute, Azerbaijani was to be taught in all district schools of Ganja, Shusha, Nukha (present-day Shaki), Shamakhi, Quba, Baku, Derbent, Yerevan, Nakhchivan, Akhaltsikhe, and Lankaran. From the early 16th century up to the course of the 19th century, these regions and territories were all ruled by the Iranian Safavids, Afsharids and Qajars until the cession of Transcaucasia proper and Dagestan by Qajar Iran to the Russian Empire per the 1813 Treaty of Gulistan and the 1828 Treaty of Turkmenchay.

Azerbaijani served as a lingua franca throughout most parts of Transcaucasia except the Black Sea coast, in southern Dagestan, the Eastern Anatolia Region and Iranian Azerbaijan from the 16th to the early 20th centuries, alongside the cultural, administrative, court literature, and most importantly official language of all these regions, namely Persian.
