This document discusses the criteria for statehood and territorial sovereignty. It outlines three theories of state recognition - constitutive, declaratory, and hybrid. The constitutive theory holds that recognition alone makes an entity a state. The declaratory theory is that an entity becomes a state by meeting qualifications like population and government, regardless of recognition. The hybrid theory is a compromise, where an entity can exist as a state by meeting qualifications but only achieves full potential after recognition. The document also discusses recognition of new governments and the criteria like effective control and representation that new governments must meet to be recognized.
