The emergence of the Indian Ocean region as an important geo-political arena is being studied across a range of disciplines. Yet while the Indian Ocean has figured in Swahili studies and analyses of East and Southern African diasporic communities, it has remained outside the mainstream of African Studies. This introduction provides an overview of emerging trends in the rich field of Indian Ocean studies and draws out their implications for scholars of Africa. The focus of the articles is on one strand in the study of the Indian Ocean, namely the role of print and visual culture in constituting public spheres and nationalisms in, across and between the societies around the Ocean.The themes addressed unfold between Southern and East Africa and India as well as along the African coast from KwaZulu-Natal through Zanzibar and Tanzania to the Arab world. This introduction surveys debates on print culture, newspapers and nationalism in African Studies and demonstrates how the articles in the volume support and extend these areas of study. It draws out the broader implications of these debates for the historiographies of East African studies, Southern African studies, debates on Indian nationalism and Islam.
