Eastern Chalukyas Emblem.

Eastern Chalukyas were a South Indian dynasty whose kingdom was located in the present day Andhra Pradesh. Their capital was Vengi and their dynasty lasted for around 500 years from the 7th century until c. 1130 C.E. when the Vengi kingdom merged with the Chola empire. The Vengi kingdom was continued to be ruled by Eastern Chalukyan kings under the protection of the Chola empire until 1189 C.E., when the kingdom succumbed to the Hoysalas and the Yadavas. They had their capital originally at Vengi near Nidadavole of the West Godavari district end later changed to Rajamahendravaram (Rajamundry).
Eastern Chalukyas were closely related to the Chalukyas of Vatapi (Badami). Throughout their history they were the cause of many wars between the more powerful Cholas and Western Chalukyas over the control of the strategic Vengi country. The five centuries of the Eastern Chalukya rule of Vengi saw not only the consolidation of this region into a unified whole, but also saw the efflorescence of Telugu culture, literature, poetry and art during the later half of their rule. It can be said to be the golden period of Andhra history.
