A sovereign state is a state that has the highest authority over a territory. It is commonly understood that a sovereign state is independent. When referring to a specific polity, the term "country" may also refer to a constituent country, or a dependent territory.
A sovereign state is required to have a permanent population, defined territory, a government not under another, and the capacity to interact with other sovereign states. In actual practice, recognition or non-recognition by other states plays an important role in determining the status of a country. Unrecognized states often have difficulty engaging in diplomatic relations with other sovereign states.
