Political institutions (Global Politics HL)

The big idea: A political institution is an established, rule-based body that organises political life. Institutions give politics stability and continuity — they outlast the individual leaders who pass through them.

Leaders come and go, but the bodies they work in stay. A parliament, a court, the UN — these are institutions: durable structures with their own rules that keep politics running over time.

• Domestic institutions — a parliament, the courts, a central bank and the civil service.
• International institutions — the UN, the EU and the WTO.

More than an IGO: An IGO is one kind of institution. But 'institution' is broader: any established set of rules and bodies — from a country's constitution to a global trade system — that shapes how politics is done and constrains even the powerful.

A powerful example of a political institution is the European Union, which binds its member states together far more deeply than a normal alliance.

Case study — the European Union (EU): The EU is a deep institution: member states share rules, a single market, a parliament and a court. By joining, states lock in cooperation and agree to follow shared rules — even when a particular decision goes against them.

The EU shows what institutions do: they make cooperation routine and durable, provide shared rules and courts, and constrain members. But they also limit sovereignty — which is why membership is sometimes contested (as with Brexit).

The key point: Institutions turn one-off deals into lasting cooperation. They reduce uncertainty, lock in commitments and outlast leaders — but they also bind their members, trading some freedom for stability and shared gains.

So do institutions really shape politics — or just reflect the power of the states behind them? Weigh both sides.

Link it up: This is liberal institutionalism vs realism: liberals say institutions shape behaviour and enable cooperation; realists say they only reflect the interests of powerful states. A strong answer shows an institution doing both.

How political institutions come up in Paper 1: A Paper 1 source might show an institution shaping events. The idea is that institutions — the lasting rules and bodies of politics — outlast any single leader and channel how power is used.

Easy marks to lose: 1. Treating 'institution' as just an IGO. It is broader — any established rule-based body.



2. Only one side. Weigh 'institutions shape' against 'they just reflect power'.



3. No real example. Use the EU (or the WTO).



4. Forgetting continuity. Institutions outlast individual leaders.
