Comparing Unitary and Federal Systems of Governance

Quick fact

In a unitary system, the central government holds ultimate sovereignty and can create or abolish subnational units, while in a federal system, regional governments are constitutionally protected and share sovereignty with the national government.

Why this is interesting
