Pro-annexation refers to the support or advocacy for the incorporation of a territory into a sovereign state, particularly in the context of Hawaii's annexation by the United States. This term highlights the political, social, and economic motivations that drove individuals and groups to favor annexation, often underpinned by ideas of American expansionism and manifest destiny. The pro-annexation movement played a crucial role in shaping the fate of Hawaii during the late 19th century as it transitioned from an independent kingdom to a territory of the United States.
