What does it mean to secede from the US?

To secede from the U.S. means that a state or region seeks to withdraw from the Union and establish itself as an independent entity. This process involves rejecting federal authority and often requires a legal or political mechanism to formalize the separation. Secession has historical roots, most notably during the Civil War, where Southern states attempted to leave the Union, leading to significant conflict and debate over the legality and morality of such actions. The U.S. Constitution does not explicitly provide a legal framework for secession, making it a contentious and complex issue.
