Naval Diplomacy and the Making of an Unwritten Alliance: United States-Brazilian Naval Relations, 1893-1930

This dissertation explores U.S.-Brazilian relations through the prism of naval diplomacy between 1893 and 1930. Broadly, this dissertation explains the growth of U.S. naval involvement in Brazil, emphasizing the motives of Brazilian and American policymakers, and the role of naval officers in strengthening bilateral relations. This study begins by examining the Brazilian Navy Revolt of 1893-94, contextualizing it within the formative years of the Brazilian Republic, while discussing U.S. naval intervention in the conflict. It then explores U.S.-Brazilian naval relations in the early twentieth century, explaining the growing association between the two countries\u27 navies after the turn of the century. That collaboration culminated in cooperation during World War I, and with the establishment of an American Navy Commission to teach at the Brazilian Naval War College. Finally, this dissertation explores the dynamics of the U.S. Navy Mission in Brazil during the first formative years after its establishment in 1922. Introducing naval diplomacy to the historiography of U.S.-South American relations illuminates the origins of American influence in Brazil, including the crucial role of Brazilians in pursuing closer ties, as well as the development of a U.S. policy focused on reducing European influence, promoting regional security, and increasing U.S. commercial power in the region
