Some historians suggest that the Kathi people are basically Scythians who migrated to Surashtra (referred to as Saraostus as well, by Greeks) around second century B.C.
Kati is the name of an ancient tribe, which in Afghanistan has given its name to the Katawaz district of Ghazni ; they are the same people, apparently, as the Kathi of the Punjab, whose ancestors opposed Alexander, and whose posterity afterwards spread southwards and gave their name to an extensive country, the modern Kathiawar.
