 One of the main characteristics of Swahili literature is the relative heterogeneity of the Swahili language.One can find works written in Kiamu, Kimvita, Kipemba, Kiunguja, Kimrima, Kimtang'ata, Ki-Dar es Salaam and Ki-Nairobi which are considered varieties of Swahili.Swahili literature has been sometimes characterized as Islamic by some western scholars such as Jan Knappert.
