Devarattam ("dance of the gods") is the dance of the Kambalathu Nayakar community of Tamil Nadu, who believe that they are the direct descendants of the 'devas' or gods. The dance involves fast and fluent movements to the rhythmic sound of Deva Thunthubi, a drum-shaped percussion instrument.
Today, the dance is performed during festivals, marriages and other social occasions. Traditionally, it was performed when a king returned with his army after a successful battle..
