States are sovereign, but they also join groups to trade, defend each other or solve shared problems. Such groups sit "above" the state.
Key idea
A supranational organization links three or more states that agree to cooperate, sharing some decisions. Examples: the United Nations (1945), the European Union, NATO (1949, a defense alliance), the African Union (2002, following the Organization of African Unity of 1963) and ASEAN (1967, the Association of Southeast Asian Nations).
| Organization | Main purpose | How binding? |
|---|---|---|
| United Nations (193 members) | Peace, security, cooperation on health, food, refugees and more | Most decisions are recommendations; Security Council decisions can bind members |
| European Union (27 members) | A single market, shared laws, free movement; many members share the euro | Very: EU law applies in every member |
| NATO | Mutual defense: an attack on one is treated as an attack on all | Binding for defense commitments |
| African Union (55 members) | Cooperation, peace and development across Africa | Works mostly by agreement |
| ASEAN | Trade and cooperation in Southeast Asia | Works by consensus; looser than the EU |
Why it works
Why give up any control? Small and medium states gain bargaining power, bigger markets and shared security by acting together. A business in one EU country can sell in all 27 under one set of rules. The cost is that some decisions are made jointly rather than at home, and people in member states debate how much should be shared. Geographers describe that debate and the trade-offs on each side.
Worked example: Supranational or not?
Which is a supranational organization: (a) a city council, (b) a trade agreement among eight countries with a shared secretariat, (c) a national army?
- Supranational means above the state: several states joined together.
- A city council is below the state; a national army belongs to one state.
Answer: (b), the eight-country trade group.
Worked example: Matching purpose
A group of countries promises that an attack on any one of them will be treated as an attack on all. What kind of organization is this, and what is a real example?
- The promise is about defense, not trade.
- A mutual-defense alliance in Europe and North America, founded in 1949, is NATO.
Answer: A military alliance; NATO.
Common mistake
Thinking joining means giving up all sovereignty. Members share some decisions; how much varies, from the EU's common laws to looser groups that work by agreement. Members remain states: they keep their own governments, and they can leave.
