Like the rest of the country, Kerala too had a temple-dance tradition, Dasiyattam, which was introduced from Tamil Nadu. Many kavyas and champus written from 12th century onwards describe courtesans and their social life. These extolled the virtues of the highly polished courtesans who were well-versed in the sensuous tradition of love poetry. Oriya poet Jayadeva's Geeta Govindam, one of the most revered works in classical Sanskrit poetry, celebrating the divine love of Radha and Krishna was introduced in Kerala with the spread of the Bhakti movement, led by Chaitanya Mahaprabhu in the 16th century.

Martha Graham saw it as European and Imperialistic, having nothing to do with the modern American people. Merce Cunningham, while using some of the foundations of the ballet technique in his teaching, approached choreography and performance from a totally radical standpoint compared to the traditional balletic format.
