ELI5: Explain Like I'm 5

Sovereign state

A sovereign state is a country that has its own government and makes its own rules. It is independent and free from interference from other countries. All people living within its borders are citizens of the sovereign state and are governed by its laws and regulations. Think of it like a family: the family has a mother, a father, and the children, who all live in their own house and make their own rules. That family is like a sovereign state.
