During the period 1010–1153, the Chola territories stretched from the islands of the Maldives in the south to as far north as the banks of the Godavari River in Andhra Pradesh. Rajaraja Chola conquered peninsular South India, annexed parts of which is now Sri Lanka and occupied the islands of the Maldives. His son Rajendra Chola sent a victorious expedition to North India that touched the river Ganges and defeated the Pala ruler of Pataliputra, Mahipala. In 1025, he also successfully invaded cities of Srivijaya of Malaysia and Indonesia.[5] The Chola invasion ultimately failed to install direct administration over Srivijaya, since the invasion was short and only meant to plunder the wealth of Srivijaya. Chola rule or influence on Srivijava would last until 1070 when the Cholas began to lose almost all of its overseas territories. The Later Cholas (1070-1279) would still rule portions of Southern India. The Chola dynasty went into decline at the beginning of the 13th century with the rise of the Pandyan dynasty, which ultimately caused their downfall.[6]
The Cholas succeeded in building the greatest thalassocratic empire in the history of India, thereby leaving a lasting legacy. Their patronage of Tamil literature and their zeal in the building of temples has resulted in some great works of Tamil literature and architecture. The Chola kings were avid builders and envisioned the temples in their kingdoms not only as places of worship but also as centers of economic activity.[7] They were also well known for their art, specifically temple sculptures and 'Chola bronzes', exquisite bronze sculptures of Hindu deities built in a lost wax process they pioneered; that continues (to a certain extent) to this day. They established a centralized form of government and a disciplined bureaucracy. The Chola school of art spread to Southeast Asia and influenced the architecture and art of Southeast Asia.[9][10] The medieval Cholas are best known for the construction of the magnificent Brihadisvara temple at Thanjavur, commissioned by the most famous Chola king, Rajaraja Chola in 1010 CE.
