Kathakali is a major form of classical Indian dance. It is a "story play" genre of art, but one distinguished by the elaborately colorful make-up, costumes and face masks that the traditionally male actor-dancers wear. Kathakali is a Hindu performance art in the Malayalam-speaking southwestern region of Kerala.

Kathakalī's roots are unclear. The fully developed style of Kathakalī originated around the 17th century, but its roots are in the temple and folk arts (such as krishnanattam and religious drama of the kingdom of the Zamorin of Calicut) southwestern Indian peninsula), which are traceable to at least the 1st millennium CE. A Kathakali performance, like all classical dance arts of India, synthesizes music, vocal performers, choreography and hand and facial gestures together to express ideas. However, Kathakali differs in that it also incorporates movements from ancient Indian martial arts and athletic traditions of South India. Kathakalī also differs in that the structure and details of its art form developed in the courts and theatres of Hindu principalities, unlike other classical Indian dances which primarily developed in Hindu temples and monastic schools.
