The Bhakti movement of late medieval Hinduism started in the 7th century, but rapidly expanded after the 12th century. It was supported by the Puranic literature such as the Bhagavata Purana, poetic works, as well as many scholarly bhasyas and samhitas.This period saw the growth of Vashnavism Sampradayas (denominations or communities) under the influence of scholars such as Ramanujacharya, Vedanta Desika, Madhvacharya and Vallabhacharya. Bhakti poets or teachers such as Manavala Mamunigal, Namdev, Ramananda, Sankardev, Surdas, Tulsidas, Eknath, Tyagaraja, Chaitanya Mahaprabhu and many others influenced the expansion of Vaishnavism.Even Meera (princess of Mehwar and Rajasthan) took part in this specific movement. These Vaishnavism sampradaya founders rejected Shankara's doctrines of Advaita Vedanta, particularly Ramanuja in the 12th century, Vedanta Desika and Madhva in the 13th, building their theology on the devotional tradition of the Alvars (Sri Vaishnavas).In North and Eastern India, Vaishnavism gave rise to various late Medieval movements Ramananda in the 14th century, Sankaradeva in the 15th and Vallabha and Chaitanya in the 16th century. Historically, it was Chaitanya Mahaprabhu who founded congregational chanting of holy names of Krishna in the early 16th century after becoming a sannyasi.
