Unified under the famous Gupta Dynasty, the north of India touched the skies as far as administration and the Hindu religion were concerned. Little wonder then, that it is considered to be India’s golden age. By 600 BC, approximately sixteen dynasties ruled the north Indian plains spanning the modern day Afghanistan to Bangladesh. Some of the most powerful of them were the dynasties ruling the kingdoms of Magadha, Kosla, Kuru and Gandhara.
