History
The legend says that Lord Krishna renounced war in Mathura for the greater good (and hence the name Ranchodrai) and founded (and settled in) Dwarka. It is said that after years of damage and destruction by the sea, this is the 7th city of Dwarka.
If Dwaraka excavations throw a flood of light on the history of the city which was associated with the life events of Krishna, the underwater excavations of Ayodhya situated on the bank of the river Sarayu might yield valuable information about the historicity of Rama, his age and contemporary urban status.
Dwaraka was a city-state extending upto Bet Dwaraka (Sankhodhara) in the north and Okhamadhi in the south.
Dwarakas existence disproves the belief held by Western archeologists that there was no urbanization in the Indian subcontinent from the period between 1700 BC.
