Like the Persian Rug that exhibits numerous colors and forms in a dazzling display of warmth and creativity, Persian culture is the glue that bonds the peoples of western and central Asia. The Caucasus and Central Asia occupy an important place in the historical geography of Persian civilization. Much of the region was included in the Pre-Islamic Persian empires, and many of its ancient peoples either belonged to the Iranian branch of the Indo-European peoples, or were in close cultural contact with them In the words of Iranologist Richard Nelson Frye:
“Many times I have emphasized that the present peoples of central Asia, whether Iranian or Turkic speaking, have one culture, one religion, one set of social values and traditions with only language separating them.”
The Culture of Persia has thus developed over several thousand years. But historically, the peoples of Islamic Republic of Iran, Tajikistan, Uzbekistan, Turkmenistan, Afghanistan, Azerbaijan, and Kyrgyzstan originate from the same or similar stock, and are related to one another as part of the larger group of peoples of Greater Iran. Armenia, Georgia, and Daghestan were also well within the sphere of influence of Persian culture as well, as can be seen from the many remaining relics, ruins, and works of literature from that region.
In particular, Iran, Afghanistan, and Tajikistan have been able to almost fully retain their Persian identity, while the other aforementioned entities still exhibit considerable traces of their Iranian past.
