Literature in Iran
Persian is Iran's official language and the language of the country's ethnic majority (i.e., the Persians), and Persian literature has been the country's most influential literary tradition. Apart from Iran, Persian literature was used and developed further through several medieval Persianate societies in Asia Minor, Central Asia, and South Asia, and the language is still used widely in Central Asia (Tajikistan and Uzbekistan) and Afghanistan.
Languages of Iran
The first legislation which granted the Persian language its status was initiated back in 1906, as part of an electoral law that positioned it as the official language of the state of Iran, its government, its political institutions and its legal system. In the course of time this enactment followed by others, which eventually lead to a monolingual policy by the Iranian regime.
