Mimkut is the harvest festival of the Kukis. Kukis of Nagaland celebrate this festival on 17th Kuki month of Tolbol (January) every year. The celebration lasts one week. Besides Mimkuut, Kukis celebrate Chapphou Kuut Chavang Kuut as well as other smaller festivals.It is believed that Mimkuut and other festivals, came into being from the fact that in order to appease Thilha (Demon) the people sacrifice and at the same time they also believed in the existence of a Supreme God whom they call “Chung Pathen” (Heavenly God). To get the blessings of such gods the village Medicine man (Thempu) would sacrifice fowls to propitiate the spirit of the Demon-god by performing a series of rituals and prayer.
