When I was young, there was ‘Jai Andhra’ movement around, which was for a separation of Telengana away from Andhra Pradeash. Now the calls I hear are for ‘United Andhra’.
The key is “Hyderabad”, like a Kohinoor diamond among Indian cities. Who doesn’t want the Kohinoor for themselves? Unfortunate that Telangana area people want Hyderabad for themselves, while Andhra area people are willing to share. (Though it is suspected that it is due to their investments there)
