A secession convention is a formal assembly of representatives from a specific region or state that gathers to discuss and decide on the matter of secession from a larger political entity, such as a nation. In the context of Florida's history, this term is crucial as it refers to the state's pivotal decision-making moment during the Civil War era, where Florida officially chose to break away from the Union and join the Confederacy. The convention often involved debates about state rights, economic factors, and the political climate leading up to the Civil War.
