Taking the case of Bharatanatyam, a popular form of classical dance in the Indian diaspora, this article deals with the following: 1. how bharatanatyam plays an important role in fulfilling the cultural needs and asserting identity of Indian diaspora community 2. brief history of bharatanatyam in India and its diaspora (both colonial and post colonial/ new diaspora) 3. bharatanatyam beyond diaspora- glogal harmony, cultural diplomacy, 4. cultural interaction in the international arena and its impact on bharatanatyam. These four dimensions intersect one another in significant ways. An attempt has been made in this article to highlight these dimensions under different sections.
