Ramanuja (traditionally, 1017–1137 CE) was a Hindu theologian, philosopher, and scriptural exegete, born in a Tamil family in the village of Sriperumbudur, Tamil Nadu. He is also known as Sri Ramanujacharya, Udayavar, Ethirajar (Yatiraja), Emberumannar and Lakshmana Muni-Kunju. His descendants are known as "swayamacharya" (which is also a division in Iyengar community). He is seen by Sri Vaishnavism as the most important acharya (teacher) of their tradition who followed Nathamuni and Yamunacharya, and by Hindus in general as the leading expounder of Vishishtadvaita, one of the classical interpretations of the dominant Vedanta school of Vedic philosophy.
