Heya,
This may be your answer:--
The Chola dynasty was one of the longest-ruling dynasties in the history of southern India. The earliest datable references to thisTamil dynasty are in inscriptions from the 3rd century BCE left by Ashoka, of the Maurya Empire. As one of the Three Crowned Kings ofTamilakam, the dynasty continued to govern over varying territory until the 13th century CE.

The heartland of the Cholas was the fertile valley of the Kaveri River, but they ruled a significantly larger area at the height of theirpower from the later half of the 9th century till the beginning of the 13th century. The whole country south of the Tungabhadra was united and held as one state for a period of two centuries and more.[4] Under Rajaraja Chola Iand his successors Rajendra Chola I,Rajadhiraja Chola, Virarajendra Chola andKulothunga Chola I the dynasty became a military, economic and cultural power in South Asia and South-East Asia.[5] The power of the new empire was proclaimed to the eastern world by the expedition to the Ganges whichRajendra Chola I undertook and by the naval raids on cities of the maritime empire ofSrivijaya, as well as by the repeated embassies to China.[6] The Chola fleet represented the zenith of ancient Indian sea power.

During the period 1010–1153, the Chola territories stretched from the islands of theMaldives in the south to as far north as the banks of the Godavari River in Andhra Pradesh.[7] Rajaraja Chola conquered peninsular South India, annexed parts of which is now Sri Lanka and occupied the islands of the Maldives. Rajendra Chola sent a victorious expedition to North India that touched the river Ganges and defeated thePala ruler of Pataliputra, Mahipala. He also successfully invaded cities of Srivijaya ofMalaysia and Indonesia.[8] 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.[9][10]

The Cholas left 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.[5] The Chola kings were avid builders and envisioned the temples in their kingdoms not only as places of worship but also as centres of economic activity.[11][12]They pioneered a centralised form ofgovernment and established a disciplined bureaucracy. The Chola school of art spread to Southeast Asia and influenced the architecture and art of Southeast Asia.[1
