Of the various modern languages used in Iran, Persian, various dialects of which are spoken throughout the Iranian Plateau, has the most influential literature. Persian has been dubbed as a worthy language to serve as a conduit for poetry, and is considered one of the four main bodies of world literature. In spite of originating from the region of Persis (better known as ''Persia'') in southwestern Iran, the Persian language was used and developed further through Persianate societies in Asia Minor, Central Asia, and South Asia, leaving massive influences on Ottoman and Mughal literatures, among others.
