Aryana and it was a province of Persia. Modern day Afghanistan is actually in fact an Iranian country yet branched off. The people are also Iranian peoples. The Afghans also known as Pashtuns are a larger tribe of the Iranian peoples whom reside in Afghanistan. We also have the Tajik ethnicity who are actually Eastern Iranians or also known as ( Fars, Persians, Iranians) The term Tajik is actually an older term which was used by the Turks to distinguish the Persians( Iranians) from the non Iranians. Today that terms still is around and even in some parts of Iran where they speak Turk, they refer to Iranians (farsi speakers) as Tajiks. Hope that answered your question.

The question makes a somewhat-incorrect initial claim. As can be seen in the above map, Iraq and Afghanistan were regions that came under the historic control of Persia on different occasions. However, these regions were never called "Persia". Iraq generally went by the name "Mesopotamia" and Afghanistan had several names, such as North Khorasan, Parthia, Bukhara, etc.The historic country of Persia is properly identified with the modern Islamic Republic of Iran, which is its successor-state (post-revolution).
The population of South Khorasan Province is 636,420.
