When in antiquity did it become unfashionable to indentify yourself as a Bharatiya/Hindu?
Historically the Central Asian invaders ,contrary to British colonialist propaganda, were invariably defeated by strong Indian armies. I am of course talking about the Scythians and Huns in particular.Huns had defeated the mighty Chinese and the Roman Empire but they had met their match in Samudra Gupta ,Yashodharma and Baladitya Only the Yueh Chi/Kushans who carved an empire in Northwestern India who managed escaped Indian retribution. When they were successful such as the Sakasthan empire, they were got their ass handed to them by Satavahana Andhra kings such as Gautamiputra Satakarni. His efforts in the Deccan and Malwa had the domino effect on their powers in the northwest(About 1700 years later, this would be inversed when the Ahmad Shah Abdali,possibly descended from Scythians, squashed the Marathas,descendents of Satavahanas, at Panipat thus effecting their southern holdings) No sooner than they started ruling India they immediately started worshipping Hindu and Buddhist
