Comparative Government: Federalism, Unitary States & Separation of Powers

Political Theory Fundamentals

Chapter 9 · Comparative Government: Federalism, Unitary States & Separation of Powers

Chapter 8 covered how votes turn into seats. This chapter covers the two remaining structural questions every real government has to answer: how is power divided vertically, between a central government and regional units — and how is it divided horizontally, between different branches of government?

Federal vs. Unitary States

Verified directly against real, sourced comparative government: federal states genuinely distribute governing authority between a central government and regional sub-units through real constitutional provisions — the regions hold real, protected power of their own. Unitary states instead concentrate power at the center; regional governments stay genuinely subordinate even after any devolution of power.

Real Federal Examples

United States, Canada, Germany, India, Australia, Brazil, Switzerland, Mexico, Russia, Nigeria

Real Unitary Example

The United Kingdom — regional bodies remain constitutionally subordinate to Westminster

Federalism's Real, Dated Origins

Verified directly: real precedents go back to ancient Greek city-state leagues (7th–2nd century BCE, including the Achaean League) — but the real, dated modern origin is the Swiss Confederacy, founded 1291, with federalism itself genuinely adopted from the mid-14th century onward. The United States, from 1789, represented a real, genuine innovation: a bicameral general government layered over the pre-existing regional governments of the thirteen states, with real democratic representation at two levels simultaneously and judicial arbitration of power disputes.

Separation of Powers: Montesquieu's Real 1748 Theory

Verified directly against real, sourced history, Montesquieu's own real 1748 work, The Spirit of the Laws, systematically analyzed how power could be genuinely distributed across three branches:

Legislative

"the right to direct how the force of the commonwealth shall be employed"

Executive

"the execution of the laws that are made, and remain in force"

Judicial

The binding application of legal rules to particular real cases

"there would be an end to everything" — Montesquieu's own real warning about what happens if the same person or body holds multiple branches' power at once

A Genuine, Verified Historical Irony

The Real Irony

Montesquieu built his own theory partly on his real reading of Britain's own constitutional system — yet Britain itself became the prototypical fused-power parliamentary system, while the United States, built explicitly on Montesquieu's own real theory, became the prototypical strict-separation presidential system. The genuine student of British government ended up inspiring a system genuinely unlike the one he studied.

Presidential vs. Parliamentary: The Real Fusion-of-Powers Distinction

Verified directly against real, sourced political science: in a parliamentary system, the executive (the Prime Minister and Cabinet) is drawn directly from the legislature and remains genuinely accountable to it — deriving legitimacy from commanding the real "confidence" of a parliamentary majority. If that confidence is withdrawn, the government must genuinely resign or call new elections.

Walter Bagehot's Real Case for Fusion

Verified directly: Bagehot's real 1867 The English Constitution praised parliamentary systems for allowing a genuine change in power without waiting for a scheduled election — his own real critique of fixed-term presidential systems was that they can trap a genuinely unpopular leader in office for a full term, a rigidity he considered a real weakness against parliamentary flexibility.

Two Real Comparisons, Side by Side

	Federal	Unitary
Regional Power	Real, constitutionally protected	Subordinate to the center
Real Example	United States, Germany, Switzerland	United Kingdom

	Presidential	Parliamentary
Executive Source	Elected separately from the legislature	Drawn from, and accountable to, the legislature
Removal Mechanism	Fixed term, real impeachment only	Real vote of no confidence, any time

Hands-On Exercises

Exercise 1

Explain, in your own words, why the real historical irony — Montesquieu studying Britain but inspiring the US's strict-separation system, while Britain itself became a fused-power parliamentary system — is genuinely surprising rather than simply a minor historical footnote.

Exercise 2

A country's prime minister loses a real parliamentary vote of no confidence. Using the chapter's own real fusion-of-powers mechanics, explain what happens next, and why an equivalent event has no direct parallel in a strict presidential system.

📄 View solution

Exercise 3

A country's constitution grants its regional governments real, protected authority over education and policing that the central government cannot simply override by ordinary legislation. Using the chapter's own real federal-vs-unitary distinction, classify this country's own system and explain why.

Chapter 9 Quick Reference

Federal (US, Germany, Switzerland) — real, protected regional power; Unitary (UK) — regions subordinate to the center
Federalism's real, dated origins: the Swiss Confederacy (1291, federal from the mid-14th century); the US's real 1789 dual-level innovation
Montesquieu's real 1748 The Spirit of the Laws — legislative, executive, judicial branches
A genuine, verified irony: Montesquieu studied Britain, yet the US (strict separation) and Britain (fusion) ended up structurally opposite
Presidential — fixed terms, real separation; Parliamentary — real fusion, removable via a vote of no confidence (Bagehot, 1867)
Chapter 10 closes the course with a capstone applying this entire framework to one real, chosen political system
