Iran (i/ɪˈrɑːn/ or /aɪˈræn/; Persian: ایران [ʔiˈɾɒn] ( listen)), officially the Islamic Republic of Iran (Persian: جمهوری اسلامی ایران, Jomhuri-ye Eslāmi-ye Irān), is a country in Western Asia. The name "Iran", which in Persian means "Land of the Aryans", has been in native use since the Sassanian era, in antiquity. It came into use internationally in 1935, before which the country was known to the Western world as Persia (pron.: /ˈpɜrʒə/ or /ˈpɜrʃə/). Both "Persia" and "Iran" are used interchangeably in cultural contexts; however, "Iran" is the name used officially in political contexts.
