ABSTRACT The German Empire collapsed at the end of the First World War, necessitating a re-negotiation of the legal and social status of its former imperial subjects. This article discusses the wartime experience of Paul Messi, a Cameroonian language assistant at the Colonial Institute, Hamburg. Messi moved to Germany in 1913 to succeed his uncle, Karl Atangana who had returned to Cameroon to become Paramount Leader of the Ewondo and Bane. Atangana had secured the position in Germany for his nephew along with providing him with a stipend. The outbreak of war saw Messi stranded in Hamburg, suffering from ill health and cut off from financial assistance. However, due to Atangana’s petitioning to the German government, his daughter Katharina, and Messi were reunited in Madrid before repatriation in 1919. The return to Cameroon was difficult, Messi, despite his desire to leave Germany, was treated as a suspect person by the French authorities. Focusing on Messi’s account of his experiences, this paper highlights how the war not only disrupted intra-empire familial connections but also how these connections enabled a negotiated return to Mandate Cameroon in the early post-war period.
