branch of Telugu Cholas, feudatory of the Western Chalukyas of Kalyani appointed them as rulers of Pakanadu for helping in the war between Cholas and Chalukyas. They ruled over the region consisting of the Nellore, Kadapa, Chittur and Chengalput districts with Vikramasimhapuri (modern Nellore) as their head capital.
Tikka (1223–1248) defeated both the Hoyasala and the Pandyas and got the Tondaimandalam region and assumed the title Cholasthapanacharya. During the reign of Tikka's son and successor Manumasiddhi II (1248–1263), Nellore faced lot of attacks from other Chalukyas and Pandyas. Tikkana visited Ganapatideva of Kakatiyas and gained military support for his king. About the year 1260, a dangerous feud broke out between Manumasiddhi and Katamaraju, the chief of Erragaddapadu in Kanigiri region. The feud was on the issue of the rights of the two princes to use certain wide meadows as grazing grounds for their flocks of cattle. It led to the bloody battle fought at Panchalingala near Muttukuru on the coast of river Penna. Manumasiddhi's forces led by Khadga Tikkana, the cousin of poet Tikkana won the battle, but the leader perished. This feud and the consequent battle formed the theme of the popular ballad entitled "Katamaraju Katha". Shortly after or during this battle, Manumasiddhi died and Nellore lost its significance.

Ganapati Deva, the first great king of Kakatiyas brought most of the Telugu area under his rule. Nellore was part of kakatiya kingdom in the 13th century. It changed hands between them and Pandyas few times until Prataprudra II defeated Pandyas. After the fall of Kakatiya Empire, the region was under Tuglaq and then was later under Kondavidi Reddis.
The most parts of the district were annexed by the Sangama dynasty of the Vijayanagara empire in 14th
