What is Nag
Nags are deity snakes or special snakes. Those snakes have especial roles in Hindu Mythologies.

There are various mythological beliefs about Nagpanchami and its celebration.
Mahabharata tells that Lord Krishna conquered Nag Kalia and put an end to his evil deeds on the day of Shrawan Panchami. People believe that is the reason why people started celebrating this panchami as Nag Panchami.
Kathmandu valley used to be a big lake. Nags became very angry when human drained the lake to make it livable. To protect themselves against the anger of Nagas, people gave nags certain areas as pilgrimage destinations, and promise to worship them on the day, returning harmony in nature. That is continued till date.
Lord Bhrama’s son Kashyap rishi had thirteen wives namely Aditi, Dit, Kadru, Danu, Arishta, Surasa, Sauravi, Vinata, Tamra, Krodhavasa, Ida, Khasa, and Muni. Aditi gave birth to Devta, Diti to Garud, Kadroo to Nags, Danu to Daitya.
Those Nags were the rulers of Patal lok.The great eight nags are Ananta, Vashuki, Padhmanavha, Kambala, Shankhapala, Dhartarashtra, Takshaka, and Kaliya. These Nags were very powerful and worshiped.
