Extensive contact with Arabic in its history led to a large influx of Arab vocabulary. This Farsi (Modern Persian) dialect still contains a large number of Arab terms, most borrowings have been nativised.
When Persia changed its name to Iran
In 1935 the Iranian government requested those countries which it had diplomatic relations with, to call Persia "Iran," which is the name of the country in Persian.
The suggestion for the change came with the advent of Reza Shah, Persia had turned a new leaf in its history and wanted to herald a new era in Iranian history free from British and Russian influences which had crippled the country.
Tajikistan

Tajik is a dialect of Farsi. It is spoken with some variation from Iranian Farsi.
In the written form it differs in that it uses the cyrilic alphabet, not the modified Arabic alphabet like Iran. This stems from its union with the Soviet Union and Russian influences.
Afghanistan

Dari is a dialect of Farsi.
In its written form, it uses the Arabic alphabet, so is written from right to left.
