Medieval Hindu religious reform movement
The Bhakti movement in Hinduism started in Tamilakam in the 6th century CE, spreading northwards and reaching its peak between the 15th and 17th century CE. It encompassed various sects like Vaishnavism, Shaivism, Shaktism, and Smartism, promoting devotion and salvation for all. The movement aimed to reform society through individual-focused spirituality.
