The "new Iranian" era of languages begins with the fall of the Sasanians (in 652 AD) and the domination of Islam. Eventually, all middle Iranian languages died out giving way to new Iranian languages or foreign ones. The most dominant of all of these new Iranian languages was the new or Dari Persian. In the year 875 AD Dari Persian became the official language of the independent Safarid dynasty. Since then new Persian (or Persian) has remained the official language of Iran.
