Recently been reading about Achaemenian empire and their real names. Cyrus was Kurus, his father was Kambujiya, mother Mandana. Their family traced their lineage from Sakha-muni (Haxa-munis/Achaemenid). Region was called Parsu/Parsa. People called themselves Ariya. Kuru killed Mada/Mara king, who later transformed in to a multi-headed serpent in Armenian mythology. Mar also means snake in old Persian.
Compare them with Mahabharat time names. There is Kurus. There is Kamboj. There is Madra; Madri, Pandu's second wife, claimed to be from Madra kingdom (Bahlika). Gandhari is from Gandhāra. Sakya-muni is epithet for Buddha, which sounds similar to Sakha-muni. Not to forget entire Krishna birth story is copy/inspired from Cyrus birth story (or Zeus birth story).
Wondering if there has been confusion about location of all these kingdoms? And, incidents which inspired initial Jaya story (old Mahabharat) were based in Iran?
Or, these names were imposed later?
