What is what does sovereign mean?

Sovereign refers to a person, group, or body that has the highest or ultimate authority over a territory or state. It can also be used to describe a state or nation that is independent and self-governing, with the power to make decisions and enforce laws without external interference. In international law, a sovereign state is considered equal to other sovereign states and has the ability to conduct its own foreign affairs. In modern democracies, the people are considered to be the sovereign, since they have the ultimate authority to elect their representatives and hold them accountable.
