Part of the definition of Sovereignty is the ability of a distinct body to make agreements with other bodies, without interference from outside parties. When this Sovereign is a Monarch, they are the final decision making authority, and we assume they agree with themselves (ignoring our internal conflicts). Sovereignty as the ability to make agreements therefore requires recognition to mean anything. I can't sign a contract with you if I don't recognise you. Georgia has two areas that are in dispute. The Republic of Abkhazia is only recognised by Russia, Nicaragua, Venezuela, and Nauru. South Ossetia is recognised by the first three. Georgia says the two areas are under Russian occupation, and are legally a part of Georgia.
