What is "persianization"

Persianization or Persianisation is a sociological process of cultural change in which something non-Persian becomes Persianate. It is a specific form of cultural assimilation that often includes language assimilation. The term applies not only to cultures, but also to individuals, as they acclimate to the Persian culture.

Historically, the term was commonly applied to changes in the culture of non-Iranian peoples living within the Iranian cultural sphere, especially during the early- and middle-Islamic periods such as Arabs, and various Caucasian (such as Georgian, Armenian, and Dagestani), and Turkic peoples including the Seljuqs, Ottomans, and Ghaznavids. The term has also been applied to the transmission of aspects of Persian culture, including language, to the non-Persian peoples in area surrounding Persia (modern-day Iran), such as Turkey and Central Asia.
