Rump state

A rump state is the remnant of a once much larger state, left with a reduced territory in the wake of secession, annexation, occupation, decolonization, or a successful coup d'état or revolution on part of its former territory. In the last case, a government stops short of going into exile because it controls part of its former territory.
