Answer:

Indian English literature (IEL), also referred to as Indian Writing in English (IWE), is the body of work by writers in India who write in the English language and whose native or co-native language could be one of the numerous languages of India. Its early history began with the works of Henry Louis Vivian Derozio and Michael Madhusudan Dutt followed by Rabindranath Tagore and Sri Aurobindo.[citation needed] R. K. Narayan, Mulk Raj Anand and Raja Rao contributed to the growth and popularity of Indian English fiction in the 1930s.[1] It is also associated, in some cases, with the works of members of the Indian diaspora who subsequently compose works in English.
