I want to know the answer to the following question:
After Lake Urmia, Persis then shifted over to what region?
All the background I'm provided with is that "However, Persis (Old Persian: Pārśa; Modern Persian: Pārse) was originally referred to a region settled by Persians in the west shore of Lake Urmia, in the 9th century BC.". Is that enough to answer the question?
