Borders

The line that marks where one state's land — and its sovereignty — ends and another's begins; a political creation shaped by history and power.

History and colonialism, power and war, natural features (rivers, mountains), and claims to self-determination.

The right of a people to decide their own political status and government, which can challenge existing borders.

The principle that a state's existing borders should not be changed by force — a core rule protecting stability.

They were drawn by empires with little regard for local peoples, splitting some groups across states and forcing rivals together, leaving rival claims.

Territorial integrity (don't change borders by force) versus self-determination (peoples can decide their own political status).

Because a border decides where sovereignty, power, resources, taxes and identity fall, so disputes are about all of these, not only geography.

Changing borders by force invites endless secession and war, so a strong norm against forced change protects stability and deters aggression.

Rigidly freezing unjust colonial borders traps divided peoples and lets grievances fester, so peaceful, negotiated change can resolve disputes.

Uphold the ban on changing borders by force, while supporting mediation and negotiated, consent-based settlement that protects those who live there.

Analyse the stimulus and the dispute, then recommend and justify a course of action, and synthesise the material into a judged response.

The boundaries that divide the sea between states and set their rights over it, governed mainly by the UNCLOS treaty.

The UN Convention on the Law of the Sea — the treaty that sets the rules for maritime borders and sea zones.

Territorial waters (~12nm, full sovereignty), the EEZ (~200nm, sole resource rights), and the high seas (belong to no one).

An Exclusive Economic Zone — a state's zone of sole rights to sea resources up to about 200 nautical miles, but not full sovereignty.

Control of the sea means control of fish, oil, gas, shipping lanes and strategic position — huge resources and power.

Under UNCLOS an island generates its own EEZ, so controlling a tiny island extends a state's resource rights over a vast area of sea.

It provides rules and a tribunal but cannot compel a powerful state that rejects a ruling, so disputes need negotiation, pressure or force.

An agreement where states jointly develop and share the resources of a disputed sea, setting the sovereignty question aside.

As land borders settled and sea resources grew more valuable and reachable, control of the sea became a growing source of tension.

International law (UNCLOS), resources (fish, oil, gas) and power — legal rulings only settle a dispute if the powerful accept them.

Uphold UNCLOS and the ruling, backed by collective pressure, and pursue joint development where a clean border is impossible.

A disagreement between states (or a state and a people) over where a border should be or who owns a territory, claimed on different grounds.

Land is fixed, unique and zero-sum, loaded with national identity and resources, and backing down looks weak, so compromise is politically very hard.

What one side gains, the other loses — land cannot be created or easily shared, unlike money.

Territorial (who owns the land), positional (where the line runs), functional (how the border is managed), and resource-driven.

One where the sides hold a ceasefire line rather than an agreed border, unresolved and a permanent risk of flaring up.

Through negotiation, international courts (ICJ), arbitration or mediation, often combined with creative compromise like sharing resources or autonomy.

Because a ruling only ends a dispute if both states accept it; a state that loses land it sees as its own may refuse to comply.

Going beyond the line itself — sharing resources, granting autonomy, joint administration, demilitarising or exchanging territory.

When a people see a territory as part of who they are, giving it up feels like betrayal, so leaders cannot compromise without appearing to surrender.

It avoids war for now but leaves the conflict unresolved and grievances festering, so it is a permanent risk of flaring into war.

Combine a legal or arbitrated ruling as a principled anchor with mediated, creative compromise (sharing, autonomy, guarantees) that both sides can accept.

The movement of people across borders to live in another place — forced (refugees) or voluntary (economic migrants).

A state's sovereign right to control who enters versus its human-rights duties (especially non-refoulement) to people fleeing danger.

A refugee is forced to flee danger and is protected by the 1951 Convention; an economic migrant chooses to move for work or opportunity, with fewer protections.

The binding rule that states must not return refugees to a country where they would face danger.

Migrants fill labour shortages, pay taxes, bring skills and youth to ageing societies, and send remittances that develop their home countries.

They fear pressure on jobs, services and housing, security and integration concerns, and political backlash, so they tighten borders.

People flee desperation, so walls and pushbacks divert movement to deadlier routes and smugglers, breach rights, and shift the burden to neighbours.

Flows containing both refugees fleeing danger and economic migrants seeking opportunity, which are hard to sort at the border.

Managed channels like resettlement and work visas that reduce dangerous journeys, undercut smugglers, and meet states' rights duties.

Because movement crosses many states and cannot be stopped by one closing its door, so it needs responsibility-sharing and cooperation.

Uphold non-refoulement, screen fairly, open safe legal routes, share responsibility, fund host states, and support integration.

You are given unseen stimulus and must bring your own real-world cases to analyse it, recommend a response and synthesise a judgement.

A small toolkit across land/territorial, maritime (EEZ/island) and migration/refugee borders — contemporary and well-documented.

Know its causes (colonial legacy, resources, identity), actors and their power, competing perspectives, and the response tried and how well it worked.

Use the case to make analytical points — causes, actors, perspectives, evaluation — never simply narrate its story.

Understand the stimulus, analyse the challenge with a case, recommend and justify a course of action, and synthesise a judgement.

A justified course of action — state the options, weigh them against the challenge, choose one and defend why it is best.

Pulling the stimulus, your case and the competing perspectives together into one coherent, evaluated response, not separate paragraphs.

Territorial integrity vs self-determination, law vs power, and control vs compassion — identify which the stimulus raises.

Because beyond analysis and evaluation, Paper 3 asks you to propose and justify a practical course of action to address the challenge.

The causes, the actors and their power, the competing perspectives, and a response you can evaluate and turn into a recommendation.

Make each part of the case do analytical work — explaining causes, weighing perspectives, evaluating a response — rather than telling events in order.
