My goal was to explore and to describe this beautiful art form with all of its relations, including the necessary definitions. My research covers the historical development of the theatre (e.g. Medieval, Renaissance, or Baroque theatre, etc.), the people working in a theatre, theatrical genres and staging (e.g. stage machinery, costumes, etc.). However, I opted out the Indian, Vietnamese, and Cambodian theatre, since they did not seem to be significant; as well as the different tribal rites, because they did not seem relevant to the theme.
