On the other hand, in political science, the term legitimacy refers to the popular acceptance of the authority of the outside bodies by the governing body. The governing body has no option but to accept on the every authority that is given to it by the outside superior bodies. The governing body must just take them regardless of whether they favor the country citizens or not (Cohen, 2013).
In political science, there are various relationships between the two states of sovereignty and the legitimacy. Some of these relationships include the following ones. First, in both countries that exercise either legitimacy or sovereignty, the governing bodies must have to stick by their legislative deadlocks. In a political state that uses the political sovereignty, they still have some small influential elites that all the governing bodies must adhere to. This is similar to a nation that exercises political legitimacy. They have no option other than just adhering to the authority of the governing regime. For example, in Chinese political philosophy, the political legitimacy of their rule in the government derived from the Heaven Mandate since the period of Zhou Dynasty. Due to legitimacy, those rulers who lost had no option but to accept that mandate was to rule over the people (Kalmo and Skinner, 2010).
Other than that, the other relationship between the sovereignty and legitimacy is that, in both states, there is a regime that is final. In the political sovereignty, a body detects what appears to be interference from the outside bodies. The body then decides on what should exactly be done on that, and there is nobody that can object that. Similarly, in a political legitimacy state, there is a superior body that decides on what the body of governors should do and there is no other body has the authority to object that. Taking an example in the real situation, USA as a superior state that is in controls
