Around 850, out of obscurity rose Vijayalaya, made use of an opportunity arising out of a conflict between Pandyas and Pallavas, captured Thanjavur and eventually established the imperial line of the medieval Cholas. Vijayalaya revived the Chola dynasty and his son Aditya I helped establish their independence. He invaded Pallava kingdom in 903 and killed the Pallava king Aparajita in battle, ending the Pallava reign. The Chola kingdom under Parantaka I expanded to cover the entire Pandya country. However towards the end of his reign he suffered several reverses by the Rashtrakutas who had extended their territories well into the Chola kingdom.
The Cholas went into a temporary decline during the next few years due to weak kings, palace intrigues and succession disputes. Despite a number of attempts the Pandya country could not be completely subdued and the Rashtrakutas were still a powerful enemy in the north. However, the Chola revival began with the accession of Rajaraja Chola I in 985. Cholas rose as a notable military, economic and cultural power in Asia under Rajaraja and his son Rajendra Chola I. The Chola territories stretched from the islands of Maldives in the south to as far north as the banks of the river Ganges in Bengal. Rajaraja Chola conquered peninsular South India, annexed parts of Sri Lanka and occupied the islands of Maldives. Rajendra Chola extended the Chola conquests to the Malayan archipelago by defeating the Srivijaya kingdom. He defeated Mahipala, the king of Bihar and Bengal, and to commemorate his victory he built a new capital called Gangaikonda Cholapuram ("the town of Cholas who conquered the Ganges"). At its peak the Chola Empire extended from the island of Sri Lanka in the south to the Godavari basin in the north. The kingdoms along the east coast of India up to the river Ganges acknowledged Chola suzerainty. Chola navies invaded and conquered Srivijaya in the Malayan archipelago. Chola armies exacted tribute from Thailand and the Khmer kingdom of Cambodia. During the reign of Rajaraja and Rajendra, the administration of the Chola empire matured considerably. The empire was divided into a number of self-governing local government units, and the officials were selected through a system of popular elections.

Throughout this period, the Cholas were constantly troubled by the ever resilient Sinhalas trying to overthrow the Chola occupation of Lanka, Pandya princes trying to win independence for their traditional territories, and by the growing ambitions of the Chalukyas in the western Deccan. The history of this period was one of constant warfare between the Cholas and of these antagonists. A balance of power existed between the Chalukyas and the Cholas and there was a tacit acceptance of the Tungabhadra river as the boundary between the two empires. However, the bone of contention between these two powers was the growing Chola influence in the Vengi kingdom. The Cholas and Chalukyas fought many battles and both kingdoms were exhausted by the endless battles and a stalemate existed.

Marital and political alliances between the Eastern Chalukya kings based around Vengi located on the south banks of the river Godavari began during the reign of Rajaraja following his invasion of Vengi. Virarajendra Chola's son Athirajendra Chola was assassinated in a civil disturbance in 1070 and Kulothunga Chola I ascended the Chola throne starting the Chalukya Chola dynasty. Kulothunga was a son of the Vengi king Rajaraja Narendra. The Chalukya Chola dynasty saw very capable rulers in Kulothunga Chola I and Vikrama Chola, however the eventual decline of the Chola power practically started during this period. The Cholas lost control of the island of Lanka and were driven out by the revival of Sinhala power. Around 1118 they also lost the control of Vengi to Western Chalukya king Vikramaditya VI and Gangavadi (southern Mysore districts) to the growing power of Hoysala Vishnuvardhana, a Chalukya feudatory. In the Pandya territories, the lack of a controlling central administration caused a number of claimants to the Pandya throne to cause a civil war in which the Sinhalas and the Cholas were involved by proxy. During the last century of the Chola existence, a permanent Hoysala army was stationed in Kanchipuram to protect them from the growing influence of the Pandyas. Rajendra Chola III was the last Chola king. The Kadava chieftain Kopperunchinga I even captured Rajendra and held him prisoner. At the close of Rajendra’s reign (1279), the Pandyan Empire was at the height of prosperity and had completely absorbed the Chola kingdom.
