Key concepts in Sovereignty

Key Idea: Sovereignty is a state's supreme authority over its own land and people. It has an internal side (rule at home) and an external side (independence + recognition). The big question: is sovereignty being eroded by globalization, intervention and non-state actors — or is it as strong as ever?

📚 The micros at a glance

What each micro adds

  1. 1.4.1–1.4.3 What / internal / external — Supreme authority; internal (rule at home) and external (independence + recognition). Can be pooled by choice (the EU).
  2. 1.4.4 Challenges — Globalization, supranational bodies, humanitarian intervention, huge companies, secession movements, violent non-state actors.
  3. 1.4.5–1.4.6 Intervention & R2P — Humanitarian intervention and R2P reframe sovereignty as a responsibility, not just a right.

⚖️ The debates that come up

  • Globalization limits states
  • But states still hold power
  • Judge: constrained, not abolished

  • Pooled sovereignty (EU)
  • Critics: a loss (Brexit)
  • Judge: a contested bargain

  • R2P: sovereignty as responsibility
  • But override is abusable
  • Judge: override only in extremes

Important: Saying sovereignty has 'ended' (or is untouched). Examiners reward a nuanced judgement — sovereignty is <strong>constrained but not abolished</strong>; distinguish internal from external sovereignty; and note it can be <strong>pooled by choice</strong> (EU) as well as squeezed by pressure.
Answer in your head first, then tap to reveal.

What is sovereignty? A state's supreme authority over its own territory and people — the highest power, with no one above it inside its borders.

What is the difference between internal and external sovereignty? Internal = supreme authority at home (making and enforcing laws); external = independence from outside control plus recognition as a sovereign equal by other states.

What challenges sovereignty? Globalization and interdependence, supranational bodies (EU/UN), humanitarian intervention, huge companies, secession movements and violent non-state actors.

What is pooled sovereignty? When states give up a little external sovereignty and combine it (as in the EU) to gain more influence together — supporters see it as useful, critics (Brexit) as a loss.

How does R2P change sovereignty? It reframes sovereignty as a responsibility, not just a right: a state that fails to protect its people, or attacks them, forfeits the shield of sovereignty.

Exam tips

  • Sovereignty = supreme authority; internal + external sides.
  • Judge: constrained but NOT abolished.
  • Pooled by choice (EU) vs squeezed by pressure.
  • R2P: sovereignty as a responsibility, not just a right.
