Persis

Persis (Greek: Περσίς, romanized: Persís; Old Persian: 𐎱𐎠𐎼𐎿, romanized: Parsa; Persian: پارس, romanized: Pârs), also called Persia proper, is the Fars region, located to the southwest of modern-day Iran, now a province. The Persians are thought to have initially migrated either from Central Asia or, more probably, from the north through the Caucasus. They would then have migrated to the current region of Persis in the early 1st millennium BC. The country name Persia was derived directly from the Old Persian Parsa.
