SECESSIONISM — [Noun] The doctrine or policy advocating formal withdrawal from a political union, federation, or state. From secession (from Latin secessio, meaning "a going apart, withdrawal") + the suffix -ism (denoting a doctrine or principle). Unlike separatism (a broader, often cultural yearning for distance) or autonomism (a plea for greater power within the existing frame), secessionism is the final, surgical cut of constitutional divorce. It lives in the dry crackle of a referendum ballot, the methodical uncoupling of rail lines at a new border, and the quiet, final click of a border gate locked from the inside. It is the belief that a political bond, once constitutive, can be cleanly and conclusively severed—a profoundly hopeful and hopelessly tidy fiction.
