Preservation of the Oral Traditions of the Ngoni tribe is the main intention of this research and documentation project. The Wagoni is a group of Bantu people who migrated from Swaziland from about 1840, forcing their way northwards by fighting the other tribes up to the area of the great lakes in Southern Tanzania. It is well-known that one of the main reasons for leaving Swaziland was the fear of the reign of king Chaka, the zulu who had disputes with one of his many chiefs. This is now the name of the regional capital of Ruvuma Region. It was not an easy task to settle here, since it was occupied by other tribes.
