From the 9th century to the 13th century, some powerful Chola Kings ruled the country. They supported the Brahmin-Piety traditions. They made land-gifts. They built Vishnu arid Siva temples. It was they who built some of the most imposing Siva temples at Chidambaram, Thanjavur and Gangaikonda Cholapuram. Some very beautiful bronze idols of Siva were also made at this period.
It was the Nayanars who gave encouragement to the sculptors. The Chola Kings encouraged the Nayanars and Azhvars. There were some economic motives behind this. It was the Vellalar farmers who made the economic base for the Chola rule. Naturally, the rulers wanted the support of the Vellalar farmers, who respected Azhvars and Nayanars. That is why the Chola Kings gave their full support to the Azhvars and Nayanars.
Chola kings often claimed divine support. They tried to proclaim their glory by building huge and beautiful temples. These temples were adorned with idols made of stone and metals. The tried to translate the dreams of the popular poets of the hymns into reality. The Kings also encouraged recitations of the Saiva hymns in Tamil in their temples.
They also took the initiative to collect these hymns and make it into a book form (Thevaram). The Chola King named Paranthakan I, got the metallic idols of Appar, Sanbandhar and Sundarar made and they were placed in a Siva Temple. An inscription dated 945 shows this. During festivals, the idols were carried in processions.
