A tweet by Sri Sunil Baboo shows that even in 1757 Maps, Bhagyanagar was not known as Hyderabad. It is therefore clear that the state was called Golkonda and Bhagnagar was a city there.

It is nothing but mischievous propaganda that stated that the city of Hyderabad was known by this name for 400 years. It also makes the case clear that the story of Bhagmati being converted to Hyder Begum and hence the city name was changed from Bhagnagar to Hyderabad is also nothing but propaganda.
It is clear that the city was named on the Goddess and it also makes the case for a bhavya Bhagyalakshmi temple very strong.
For decades, the Hindus are fighting a battle to save the Bhagyalakshmi temple in Hyderabad from onslaughts on numerous occasions. In 2011, we had written a detailed article on this topic – Historic Bhagyalakshmi Temple Under Siege
