Nanyadeva (IAST: Nānyadev[1]) was the founder[2][3] of the Karnat dynasty of Mithila.[4] He established his capital in Simraungadh and ruled the greater Mithila region for 50 years.[5][6]
He is known for his patronage of scholars.[7] He has been described as belonging to the Karnat KshatriyaKula and began to rule Mithila from the citadel of Simraungadh which was situated on the modern India-Nepal border, in 1097 CE. Various inscriptions and land grants belonging to Nanyadeva have been found within the region to testify to his reign.[8]
In his writings, Nanyadeva referred to himself as Mithileśwara which translates to ruler of Mithila.[9]
