The posts in this weblog are mainly about history, heritage, language, art, and culture of Persia (that is named Iran since 1934). Persia is, therefore, equal to Iran, and Persian is equal to Iranian. Note that Persian is a nationality not an ethnicity. Pars (or Fars) is the major ethnicity in Persia but there are also Persian Kurds or Arabs. Similarly, the official language in Persia is Persian (Farsi is the local name and may not be used internationally). For more details please read my posts.
