The Department of Anthropology and African Studies (ifeas) at Johannes Gutenberg University Mainz hosts a comprehensive archive on African Independence Day celebrations. Created in 2010, the archive is one of the outcomes of a large comparative research project on African national days directed by Carola Lentz. It offers unique insights into practices of as well as debates on national commemoration and political celebrations in Africa. The archive holds more than 28,000 images, including photographs, newspaper articles, documents, and objects from twelve African countries: Benin, Burkina Faso, Cameroon, Côte d'Ivoire, Democratic Republic of the Congo, Gabon, Ghana, Madagascar, Mali, Namibia, Nigeria, and Tanzania. It primarily consists of an online photo and newspaper archive (https://bildarchiv.uni-mainz.de/AUJ/; https://www.blogs.uni-mainz.de/fb07-ifeas-eng/departmental-archives/online-archive-african-independence-days/); some of the material is also stored in the physical archive on African Independence Days at ifeas as well as in the department's ethnographic collection (https://www.blogs.uni-mainz.de/fb07-ifeas-eng/ethnographic-collection/). Most of the material concerns recent celebrations, but the collection has been complemented by some documentation of earlier festivities. Archives hold many stories while they also have a story to tell in their own right. This article discusses both aspects. It first traces the history of the Online Archive African Independence Days at ifeas. It then provides an overview of the different categories of material stored in the archive and tells a few of the many stories that the photos, texts and objects contain. We hope to demonstrate that the archive holds a wealth of sources that can be mined for studies on national commemoration and political celebrations in Africa, and, more generally, on practices and processes of nation-building and state-making.
