<P> Within the modern governmental system, internal sovereignty is usually found in states that have public sovereignty and rarely found within a state controlled by an internal sovereign . A form of government that is a little different from both is the UK parliament system . From 1790 to 1859 it was argued that sovereignty in the UK was vested neither in the Crown nor in the people but in the "Monarch in Parliament". This is the origin of the doctrine of parliamentary sovereignty and is usually seen as the fundamental principle of the British constitution . With these principles of parliamentary sovereignty majority control can gain access to unlimited constitutional authority, creating what has been called "elective dictatorship" or "modern autocracy". Public sovereignty in modern governments is a lot more common with examples like the USA, Canada, Australia and India where government is divided into different levels . </P> <P> External sovereignty concerns the relationship between a sovereign power and other states . For example, the United Kingdom uses the following criterion when deciding under what conditions other states recognise a political entity as having sovereignty over some territory; </P> <P> External sovereignty is connected with questions of international law--such as: when, if ever, is intervention by one country into another's territory permissible? </P> <P> Following the Thirty Years' War, a European religious conflict that embroiled much of the continent, the Peace of Westphalia in 1648 established the notion of territorial sovereignty as a norm of noninterference in the affairs of other nations, so - called Westphalian sovereignty, even though the actual treaty itself reaffirmed the multiple levels of sovereignty of the Holy Roman Empire . This resulted as a natural extension of the older principle of cuius regio, eius religio (Whose realm, his religion), leaving the Roman Catholic Church with little ability to interfere with the internal affairs of many European states . It is a myth, however, that the Treaties of Westphalia created a new European order of equal sovereign states . </P>
