The country to which you may be referencing, is the Islamic republic of Iran. The aforementioned was known as Iran, or Persia, during the reign of Shah Reza Pahlavi, until he was overthrown, during what has come to be known as the Islamic Revolution, or Iranian Revolution, during the year 1979. I should be mentioned that Iran is the largest majority Shi'ite country in the world.
After a coup in 1953 Iran became autocratic. It became an Islamic Republic in 1979 to help keep out international influence.

Iran is its own country.
Persia became Iran.
It was the revolution in Iran in year 1979 against the reign of Shah Iran Reda Bahalwi. Accordingly, the Islamic Republic in Iran was established.
Iran has more than 7000 year history and it was an independent country-- named "Aryanna" which then changed into "Iran" and as Greeks called it "Persia"-- pretty much all of it.
