Kenyatta's government believed it necessary to cultivate a united Kenyan national culture. To this end, it made efforts to assert the dignity of indigenous African cultures which missionaries and colonial authorities had belittled as "primitive". An East African Literature Bureau was created to publish the work of indigenous writers. The Kenya Cultural Centre supported indigenous art and music, and hundreds of traditional music and dance groups were formed; Kenyatta personally insisted that such performances were held at all national celebrations. Support was given to the preservation of historic and cultural monuments, while street names referencing colonial figures were renamed and symbols of colonialism—like the statue of British settler Hugh Cholmondeley, 3rd Baron Delamere in Nairobi city centre—were removed. The government encouraged the use of Swahili as a national language, although English remained the main medium for parliamentary debates and the language of instruction in schools and universities. The historian Robert M. Maxon nevertheless suggested that "no national culture emerged during the Kenyatta era", most artistic and cultural expressions reflecting particular ethnic groups rather than a broader sense of Kenyanness, while Western culture remained heavily influential over the country's elites.
