Bhakti movement in the south was led by Alvars (Devotees of Lord Vishnu) and Nayanars (Devotees of Lord Shiva). Nayanars and Alvars belonged to the 7th and 8th centuries. There were 63 Nayanars and 12 Alvars. They all belonged to different caste background. They were against the system of caste in society. They preached the idea of Bhakti through hymn and stories in regional languages. The Chola and Pandya rulers built temples at places visited by them.
