Like the Persian rug that shows many colours and warmly and creatively arranged shapes, Persian culture is the glue that holds the peoples of Central and Western Asia together. Famous Iranologist Richard Nelson Frye said:

It is emphasized many times that the peoples of Central Asia today, whether they speak an Iranian or Turkish language, have a culture, a religion, a set of social values and traditions that only a language separates.

The culture of Persia therefore developed over many thousands of years. However, historically, the peoples of the Islamic Republic of Iran, Tajikistan, Uzbekistan, Turkmenistan, Afghanistan, Azerbaijan and Kyrgyzstan have the same origin, and are connected to each other as only part of the vast whole called the Iranian world. Armenia, Georgia and Dagestan were also within the sphere of influence of Persian culture, and this can be seen by observing the ruins, relics and literary works of this region.

In particular, Iran, Afghanistan and Tajikistan are the countries that have managed to retain their Persian identity the most, while the others mentioned still show considerable traces of their Iranian past.
