Prominent Hindu philosophers, poets and scholars such as Sripadaraya, Vyasathirtha, Vadirajatirtha, Purandara Dasa and Kanaka Dasa played an important role during this time. Though the movement found its roots in the Kannada country and later spread to other parts of South India, it was a net result of earlier devotional movements such as the Veerashaiva movement (of Vachana literature in Kannada) of northern Karnataka led by Basavanna (12th century) and the Alvar saints of Tamil Nadu (10th century). Later, Vallabhacharya in Gujarat and Guru Chaitanya were influenced by the teachings of Madhvacharya. Chaitanya Mahaprabhu's devotees started the International Society for Krishna Consciousness (ISKCON) - known colloquially as the Hare Krishna Movement.
