(in international law) The acquisition of legal sovereignty by one state over the territory of another, usually by occupation or conquest. Annexation is now generally considered illegal in international law, even when it results from a legitimate use of force (e.g. in self‐defence). It may subsequently become legal, however, by means of recognition by other states. The annexing state is not bound by pre‐existing obligations of the state annexed.
