Kerala has a rich tradition of Folklore. Folklore in this region is a spontaneous expression of human behavior and thoughts. Generally speaking, Folklore could be defined as the lore of the common people who had been marginalized during the reign of feudal Kings. The Keralites have their culture and lore which were mostly part of agricultural. Sowing, planting of nharu (seedling), clearing out the weeds, harvests etc. are the different stages of agriculture which have their typical rituals. Numerous songs and performing arts are accompanied with them. Kanyar Kali, Padayani, Mudiyettu, Thirayattam, Malavayiyattam, Theyyam, Kothamooriyattam, Nira, Puthari, etc. are some of the ritual folklore of Kerala. It was under the rule of Kolathiris, the Kings of Kolathunadu, and they codified the rituals, beliefs, taboos and folk performing arts. Even the dates of specific fertility rituals and folk performances were decided by the Kolathiris of which many are continuing even today. The Theyyam festivals, even now, are conducted as per the dates once fixed by the King.
