parts of Sri Lanka. Rajendra Chola's navy went even further, occupying coasts from Burma (now) to Vietnam, the Andaman and Nicobar Islands, Lakshadweep, Sumatra, Java, Malaya, Philippines in South East Asia and Pegu islands. He defeated Mahipala, the king of Bengal, and to commemorate his victory he built a new capital and named it Gangaikonda Cholapuram. The Cholas were prolific temple builders right from the times of the first medieval King Vijayalaya Chola. These are the earliest specimen of Dravidian temples under the Cholas. His son Aditya I built several temples around the Kanchi and Kumbakonam regions. The Cholas went on to becoming a great power and built some of the most imposing religious structures in their lifetime and they also renovated temples and buildings of the Pallavas, acknowledging their common socio-religious and cultural heritage. The celebrated Nataraja temple at Chidambaram and the Ranganathaswamy Temple at Srirangam, Tiruchirappalli, held special significance for the Cholas which have been mentioned in their inscriptions as their tutelary deities. Rajaraja Chola I and his son Rajendra Chola built temples such as the Brihadeshvara Temple of Thanjavur and Brihadeshvara Temple of Gangaikonda Cholapuram, the Airavatesvara Temple of Darasuram and the Sarabeswara (Shiva) Temple, also called the Kampahareswarar Temple at Thirubhuvanam, the last two temples being located near Kumbakonam. The first three of the above four temples are titled Great Living Chola Temples among the UNESCO World Heritage Sites.

Subsequently, as the Vijayanagara Empire went into decline after the mid-16th century, many local rulers, called Nayaks, succeeded in gaining the trappings of independence. This eventually resulted in the further weakening of the empire; many Nayaks declared themselves independent, among whom the Nayaks of Madurai and Tanjore were the first to declare their independence, despite initially maintaining loose links with the Vijayanagara kingdom. The Nayaks of Madurai and Nayaks of Thanjavur were the most prominent Nayaks of the 17th century. They reconstructed some of the well-known temples in Tamil Nadu such as the Meenakshi Temple.
