Kirat history and culture in Nepal

Nepal is a very ancient country, which has been ruled by many dynasties. Among them, the Kirat rule is taken as a very significant one, being the longest period that extended from pre-historic to historic period. In ancient Hindu scriptures, Nepal is referred as the "Kirat Desh" or "the Land of Kirats".
When the 28th Kirat King Paruka was ruling in the valley, the Sombanshi ruler attacked his regime many times from the west. Although he successfully repelled their attacks, he was forced to move to Shankhamul from Gokarna. He had built a Royal Palace called "Patuka" there for himself. The Patuka Palace is no more to be seen, except its ruins in the form of mound. "Patuka" had changed Shankhamul into a beautiful town. The last King of the Kirat dynasty was Gasti. He proved to be a weak ruler and was overthrown by the Sombanshi ruler Nimisha. It brought to the end of the powerful Kirat dynasty that had lasted for about 1225 years.
After their defeat, Kirats moved to the eastern hills of Nepal and settled down divided into small principalities. Their settlements were divided into three regions; namely, "Wallo-Kirant" or "near Kirant" that lay to the east of Kathmandu, "Majh-Kirat" or "central Kirat," and "Pallo-Kirat" that lay to the far east of the Kathmandu valley. These regions are still heavily populated by Kirats. Khambu are the inhabitants of near and central Kirat. Although, they are also quite densely populated in "Pallo-Kirat".
By religion, Kirats were originally nature worshippers. They worshipped ancestors and nature such as rivers, trees, animals and stones etc. Their primeval ancestors are Paruhang and Sumnima. Hinduism was introduced to and imposed on the Kirats only after the conquest of Gorkhali rulers whose root was in India. Kirats were quite tolerant and liberal to other religions. That was why Buddhism flourished during the Kirat rule in Nepal. Buddhism had rekindled a new interest and attitude among the people. Kirats had also built many towns. Shankhamul, Matatirtha, Thankot, Khopse, Bhadgoan and Sanga were prosperous cities with dense population. Thus, it can be safely said that the Kirat period had paved the way for further development and progress of Nepal in all sectors in future.
