 The British decided to formalise it as the language to be used across the East African region (although in British East Africa [Kenya and Uganda] most areas used English and various Nilotic and other Bantu languages while Swahili was mostly restricted to the coast).In June 1928, an inter-territorial conference attended by representatives of Kenya, Tanganyika, Uganda, and Zanzibar took place in Mombasa.The Zanzibar dialect was chosen as standard Swahili for those areas, and the standard orthography for Swahili was adopted.
