Ramanuja was a Hindu theologian, philosopher, and an exponent of the Sri Vaishnavism (Vishnu) tradition in 11th and early 12th century. Like his Vedanta peers, Ramanuja wrote a bhashya (commentary) on the Gita. Ramanuja's disagreed with Adi Shankara's interpretation of the Gita as a text on nondualism (Self and Brahman are identical), and instead interpreted it as a form of dualistic and qualified monism philosophy (Vishishtadvaita).
