Universal monarchy

A Universal Monarchy is a concept and a political situation where one monarchy is deemed to have either sole rule over everywhere (or at least the predominant part of a geopolitical area or areas) or to have a special supremacy over all other states (or at least all the states in a geopolitical area or areas).
Universal Monarchy is differentiated from ordinary monarchy in that a Universal Monarchy is beholden to no other state and asserts a degree of total sovereignty over an area, or predominance over other states.
The concept has arisen in Europe and Asia. The concept is linked to that of Empire, but implies more than simply possessing imperium.
