Mention the two earliest Bhakti Movements of Tamil Nadu, giving the main difference between them.
Two earliest Bhakti movements of Tamii Nadu were the Alvars and the Nayanars . Some of the earliest Bhakti movements (C. sixth century) were led by the Alvars (literally) those who are “immersed” in devotion to Vishnu) and Nayanars (literally, leaders who were devotees of Shiva). They travelled from place to place singing hymns in Tamil in praise of their gods.
