States, Nations, and Nation-States
A state is a sovereign government with defined borders. A nation is a group bound by shared culture, language, or history. A nation-state is a state whose borders roughly match a single nation's territory.
A state is a political and legal entity: a piece of territory with defined borders, a permanent population, and a government that has sovereignty, meaning no other power outranks it there. A nation is different. It is a group of people who feel bound together by a shared identity, built from things like language, religion, ethnicity, or a common history and sense of destiny. Nothing about being a nation requires having your own government or your own land. A nation-state is what you get when the two line up: a state whose borders contain essentially one nation, and whose population largely sees itself as that nation. Japan fits well, since the vast majority of people living within Japan's borders share Japanese language, ethnicity, and history, so state and nation nearly overlap.
Nigeria is a state but not a nation-state, because its borders were drawn by British colonizers around hundreds of distinct ethnic nations, including Hausa, Yoruba, and Igbo, none of which matches the country's shape. The state exists; the single shared nation inside it does not.
This distinction sets up the rest of the unit. Once you can separate the cultural claim (nation) from the legal claim (state), you can make sense of boundary disputes, self-determination movements, and why some groups push for devolution or independence: they are nations seeking to become states, or to reshape a state's borders to match their nation.
