A more thorough explanation: “Defederation” refers to the process of withdrawing from or dissolving a federation or a federal union. In legal contexts, it involves the disintegration or severance of the political, economic, or administrative ties that bind different states or regions under a federal system.
Example: In 1861, the Confederate states engaged in defederation from the United States, creating a separate confederation with its own government.
