The Polish ambassador traveled to Isfahan

The native Polish name for Poland is Polska. The term is derived from the Polans, a West Slavic tribe who inhabited the Warta River basin of present-day Greater Poland region (6th–8th century CE). The tribe’s name stems from the Proto-Slavic noun pole meaning field, which in-itself originates from the Proto-Indo-European word *pleh₂- indicating flatland. The etymology alludes to the topography of the region and the flat landscape of Greater Poland.
