According to the historian
Makhan Jha, there was a great scholar named
Nath Thakur at the court of a
Karnat king in Mithila. It is said that, for his scholarship he was gifted a village of name Oini by the king in
daan (donation). Those days there was a tradition that a person rewarded with a gift of village by the king was usually came to be known after the name of that village. Therefore, the scholar Nath Thakur was also called as
Oini Thakur. Later after the fall of
Karnat Dynasty in Mithila, the scholar Oini Thakur became the ruler of the region. He established the
Oiniwar Dynasty and became the first king from the Oiniwar Dynasty in Mithila. During the early period of the Oiniwar Dynasty, Oini was the court of the kingdom of Mithila. The ruins of the court of the then kingdom still exists in the form of
dih at the village. Nowadays the remains of the dih is found covered with bushes and trees. The ruins of the court is known as
Waini Dih. In the recent period, some youths of the village established idol of
Goddess Bhagwati at the dih and started worship there. == References ==
