Mythology of Kirati

Kirātas (Sanskrit: किरात) are mentioned in early Sanskrit literature as hunter tribes from the Himalayas. They are first mentioned in the Yajurveda, and in the Atharvaveda, which dates back to 16th century BC. They are often mentioned along with the Cinas "Chinese".

The Sanskrit kavya titled Kiratarjuniya (Of Arjuna and the Kirata) mentions that Arjuna adopted the name, nationality, and guise of a Kirata for a certain period to learn archery and the use of other arms from Shiva, who was considered as the deity of the Kirata. Hindu myth also has many incidents where the god Shiva imitates a married Kirati girl who later become Parvati.In Yoga Vasistha , Rama speaks of kirāteneva vāgurā "a trap  by Kiratas", so about 10th century BCE, they were thought of as jungle trappers, the ones who dug pits to capture roving deer. The same text also speaks of King Suraghu, the head of the Kiratas who is a friend of the Persian King, Parigha.
The Himalayan Kirat people practice Kiratism, calling it "Kirat religion". The Kiratis follow Kirat Mundhum. Their holy text is the Mundhum, also known as the Kirat Veda. Kirat Rai worship nature and their ancestors. Animism and shamanism and belief in their primeval ancestors, Sumnima and Paruhang are their cultural and religious practices. The names of some of their festivals are Sakela, Sakle, Tashi, Sakewa, Saleladi Bhunmidev, Chyabrung, Yokwa and Folsyandar. They have two main festivals: Sakela/Sakewa Ubhauli during planting season and Sakela/Sakewa Udhauli during the time of harvest. Khas Kiratis and Tibetan-Himalayan or Sikkimese follows Buddhism and the Kacharis of Northeast, India follows the Bathouism religion, named after Bathou which in Bodo means the five principles. The five principles are: bar (air), san (sun), ha (earth), or (fire) and okhrang (sky). The chief deity, called Bathoubwrai (bwarai: "the Elder")—omnipresent, omniscient and omnipotent—is said to have created the five principles. Though there are other minor gods and goddesses, Bathoubwrai is considered the Supreme God. The second most important deity is Mainao, the consort of Bathoubwrai, who is considered as the "protector of the rice fields". Some ethnic groups also have adopted Christianity and Hinduism religion cause of mixing up with Indian nation.

Kirat Limbu people believe in a supreme god called Tagera Ningwaphuma, who is also known as the supreme knowledge. The Kirat ancestor Yuma Sammang and god of war Theba Sammang are the second most important deities.

Limbuwan had a distinct history and political establishment until its unification with the kingdom of Gorkha in 1774 AD. During King Prithvi Narayan Shah's unification of Nepal, the present-day Nepal east of Arun and Koshi rivers was known as Pallo Kirat Limbuwan. It was divided into 10 Limbu kingdoms of which Morang kingdom was the most powerful and had a central government. The capital of Morang kingdom was Bijaypur (present-day Dharan). After the Limbuwan Gorkha War and seeing the threat of the rising power of the British East India Company, the kings and ministers of all the 10 Limbu kingdoms of Limbuwan gathered in Bijaypur to agree upon the Limbuwan-Gorkha Treaty. This treaty formally merged the 10 Limbu kingdoms into the Gorkha kingdom but it also had a provision for autonomy of Limbuwan under the "kipat" system.

After the completion of the conquest of the Kathmandu Valley in 1769, the Gorkhali army marched east towards the Kirat territory. The Sen rulers of eastern Nepal, known as Hindupati, had established a weak rule in the Kirat region by adopting a policy of mutual understanding with the local Kirat leaders. The topless bamboo tree of BuddhaSubba Temple of Dharan, Nepal is believed to be grown from bows and arrows left by Buddhikarna Raya (Tumbapo) when he was unable to kill an elephant with a single strike of arrow from his bow. After the end of Rana Regime in 2007 BS(1961 AD), when shah dynasty again ruled Nepal at that time onwards the autonomous power given to Limbu was reduced. King Tribhuwan demolished tile of Hang "King in Limbu" to Subba. When King Mahendra(Tribhuwan Son at that time only Prince) ascended the throne he banished the law which probhits other tribe right to buy land without permission of Subba (Head of Limbu) of particular area as well as levy and taxes to Subba in 1979.
