Why did Andhra Pradesh split into two states while both are Telugu speaking states?

 Telugu Speaking states are Three.

1.Tamil Nadu- The state has considerable Telungu speaking people, where the Telungu spoken is Original Thalli Telungu spoken 600 to 800 years back. It is influenced by Tamil.

2.Telangana- The telugu spoken here is influenced by Urdu as the region was a part of Hyderabad Princely state and to some extent neighbouring Marathi.

3.Andhra- The telugu spoken here is influenced by Sanskrit, as believed and propagated by many brahmins.

Telugu people differ due to regional influences.
