History of Persia

Persis, better known as Persia , or Persia proper, is a region located to the southwest of modern Iran (now Fars). 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.
