Ramasimhadeva was the fourth King of the Karnat dynasty of Mithila.
[1] Ramasimhadeva has been described as a "pious devotee and was a firm patron of sacred literature" and his reign was generally quite peaceful, in contrast to his father's.
He also created various rules that were meant to guide Hindus and officers were sent to each village to ensure these were followed.
[2] During his reign, the Tibetan monk Dharmasvamin arrived in the main Karnat capital of Simraungadh and described Ramasimhadeva as treating him with courtesy and even offering him the post of palace priest despite being a Buddhist.
