Definition
Secessionism is the advocacy of or support for the act of seceding, which is formally withdrawing from membership of a federation or body, especially a political state. Think of it as a group wanting to break away and form their own country or organization. It often arises from feelings of dissatisfaction, marginalization, or a desire for self-determination. Unlike simple disagreement, secessionism involves concrete actions and demands for separation. It's like wanting to start your own club because you don't like the rules of the existing one. π
