Understanding Federalism: Definitions and Debates

Few terms in political science are used as confidently and defined as inconsistently as federalism. Politicians invoke it to defend state autonomy, scholars argue over whether a given country even qualifies as federal, and constitutional courts reach for it to settle disputes between the centre and the regions. Yet beneath the everyday usage lies a genuine debate: what does federalism actually mean, and is the term even useful for understanding how power is shared across different levels of government? This post unpacks the leading definitions, the conceptual disagreements among scholars, and why the label continues to matter for diverse societies like ours.

What federalism actually means

At its simplest, federalism describes a system of governance in which authority is divided between a central government and constituent units such as states or provinces, with each level having a sphere of action guaranteed by a constitution rather than granted at the pleasure of the other. The defining quality is that this division is constitutionally entrenched. Neither level can unilaterally abolish the other, and both derive their authority directly from the constitution.

The most influential shorthand comes from political scientist Daniel J. Elazar, who summed up federalism as a combination of self-rule plus shared rule. Self-rule refers to the capacity of regional governments to make decisions independently within their own domains. Shared rule refers to their ability to participate in and influence decisions taken at the centre, often through representation in a second chamber of the legislature. A federal arrangement, in this view, is one that institutionally guarantees both at the same time.

Elazar pushed the idea further than a simple structural formula. He described federalism as involving a contractual linkage of a presumably permanent character that provides for power sharing, works around the question of sovereignty, and supplements rather than replaces pre-existing organic ties between communities. The word “covenant” runs through his work: federalism, for him, is partly a moral and political relationship, not merely an administrative blueprint.

Why the “self-rule plus shared rule” formula caught on

The phrase endures because it captures the dual purpose of federal systems in a few words. A purely centralised state offers unity but crushes regional distinctiveness. A loose alliance of sovereign states preserves diversity but struggles to act as one. Federalism attempts to hold both together. As Elazar noted, of the more than 160 sovereign states in existence when he wrote, the majority were multiethnic, and dozens used federal principles in some form to accommodate demands for self-rule or shared rule within their borders. The formula travels well precisely because it is not tied to any one constitution.

It is worth noting that even “shared rule” is contested. Scholars have identified at least three readings: the powers of the central government itself, the participation of regional units in central decisions, and horizontal cooperation between units without involving the centre. Switzerland, for instance, has hundreds of treaties between its cantons that regulate common standards without the federal level being involved. So even the cleanest definition contains internal ambiguity.

Debating the term: three concepts, not one

This brings us to the heart of the controversy. Much of the confusion around federalism stems from using a single word for several distinct things. The Canadian scholar Ronald L. Watts, one of the foremost authorities on comparative federal systems, argued that we should carefully separate three terms that are often used interchangeably.

Federalism, federal political systems, and federations

According to Watts, federalism is best understood not as a description of how a government is built but as a normative principle. It refers to the advocacy of multi-tiered government that combines elements of shared rule and regional self-rule, resting on the value of combining unity and diversity by accommodating distinct identities within a larger political union.

By contrast, a federal political system is a descriptive term covering a broad genus of arrangements with two or more levels of government, which includes unions, federations, confederations, federacies, and associated states. A federation is one particular species within that genus, marked by features such as two constitutionally established orders of government, a written constitution not unilaterally amendable, an umpire (usually a court) to rule on disputes, and institutions to facilitate intergovernmental collaboration. Watts pointed out that there were roughly twenty-five functioning federations in the world, containing over forty percent of the global population.

This distinction is not academic hair-splitting. It tells us that a country can embody federal principles to varying degrees without being a textbook federation, and that the same constitutional words can operate very differently in practice.

Form versus operational reality

Watts added a crucial caveat that directly concerns our own system. He warned against confusing constitutional form with operational reality. In many systems, political practice has transformed how the constitution actually works. He cited Canada and India as examples where the original constitution was quasi-federal, containing some central overriding powers more typical of unitary states. In Canada these powers fell into disuse; in India they have been used but moderated, so that the lived reality moved closer to that of a full-fledged federation. The lesson is that you cannot assess a federal system by reading the text alone.

The Indian puzzle: is the term even the right one?

Nowhere is the debate over the term more alive than in the Indian context. The Constitution famously avoids the word “federation” altogether. Article 1 declares that India “shall be a Union of States,” and the records of the Constituent Assembly show this was a deliberate choice of vocabulary. The drafters wanted to signal that the union was not a contract among pre-existing sovereign states that could choose to leave, but a permanent arrangement.

This led K.C. Wheare, the Oxford scholar who supervised Watts’s doctoral work, to label the Indian Constitution quasi-federal. He famously described it as a unitary state with subsidiary federal features rather than a federal state with subsidiary unitary features. His reasoning pointed to provisions that tilt heavily toward the centre, especially during emergencies.

A clash of labels

Wheare’s verdict was far from the last word, and the proliferation of competing labels itself illustrates the difficulty of pinning the term down. Granville Austin rejected the unitary reading and called the Indian system an example of cooperative federalism, pointing to mechanisms such as the Inter-State Council, Zonal Councils, the All India Services, and the Finance Commission that bind the centre and states together. Morris Jones described it as “bargaining federalism,” while Ivor Jennings called it a federation with a strong centralising tendency. B.R. Ambedkar, defending the design in the Constituent Assembly, argued it could be both unitary and federal according to the requirements of time and circumstances.

Some scholars have pushed back on Wheare’s framing for being ethnocentric. The criticism is that by treating the United States as the model of “true” federalism, any system that differs gets relegated to “quasi” status. If each federation is treated as unique and shaped by its own circumstances, then India’s strong centre is not a deviation from federalism but simply a different, equally valid expression of it. After all, a country facing strong secessionist pressures has good reason to build in a powerful centre.

How the courts have read it

India’s Supreme Court has wrestled with these labels too. In its emergency-era jurisprudence it leaned on the language of cooperative federalism, and in later cases concerning the National Capital Territory of Delhi and the goods and services tax it spoke of collaborative or cooperative federalism to call for greater coordination between the Union and the states. The Court has also affirmed that federalism forms part of the Constitution’s basic structure. These are not idle word choices: the term a court selects shapes how it interprets the balance of power in concrete disputes.

Is the term “federalism” actually useful?

Given all this disagreement, a fair question arises: does the concept do any real analytical work, or is it so elastic that it explains nothing? This scepticism has serious academic backing. The American political scientist William H. Riker, a towering figure in the study of federal systems, was deeply doubtful about the term’s explanatory value.

Riker’s challenge

Riker argued that federations are not born from high ideals about liberty or the common good but from a hard-headed federal bargain. In his account, central politicians offer the deal to expand the territory under their control, while regional politicians accept it to meet a common military threat or opportunity. Most provocatively, in a 1969 essay he asked whether federalism even exists and whether it matters, suggesting that in terms of actual policy outcomes and how people are governed, federalism has very little impact. For Riker, what mattered far more than constitutional structure was the organisation of political parties.

Later scholars have qualified Riker’s claims. The insistence that an external military threat is necessary for federal success does not fit cases like the European Union or Australia, where economic and cultural factors mattered. His reading of India’s origins, attributing it to central-regional bargaining, has been challenged by those who stress the hegemony of a centralist Congress Party instead. Even so, his core demand stands as a healthy corrective: do not assume the label “federal” tells you how a country is really run.

Why the concept still earns its place

Despite the critiques, most comparative scholars conclude that federalism remains indispensable, provided we use it with care. Watts drew several lessons from his lifetime of comparative study. Federal systems, he argued, provide a practical way of combining the benefits of both unity and diversity through representative institutions. At the same time, he cautioned that federalism is not a cure-all, that its success depends on respect for constitutional norms and a spirit of tolerance and compromise, and that well-designed federal institutions can help multi-ethnic and multi-national societies hold together.

The utility of the term, then, is conditional. As a slogan it explains little. As a precise analytical category, separating the normative principle from the descriptive system from the specific institutional form, it lets us compare countries as different as Switzerland, Canada, Nigeria, and India on common ground while respecting what makes each distinctive.

Bringing the threads together

The debate over the term federalism is really a debate about how much precision we owe a powerful idea. Elazar gave us the memorable formula of self-rule plus shared rule and reminded us that federalism is partly a relationship built on trust, not just an architecture. Watts gave us the disciplined vocabulary to tell a normative ideal apart from a working system and from a particular constitutional model. Wheare, Austin, and their successors showed how fiercely the labels are contested when applied to a real country, while Riker forced the field to test its claims rather than assume them.

For a society as plural as ours, the stakes are not merely terminological. Whether we describe the system as quasi-federal, cooperative, or simply federal shapes how disputes between the centre and the states are argued, how courts rule, and how much room regional identities have to breathe within a single union. The word we choose carries a theory of power inside it.

What do you think? If the same constitution can be called “quasi-federal” by one scholar and “cooperative federalism” by another, does the label reveal more about the system or about the scholar’s own benchmark? And in a union designed to be permanent yet diverse, how should we judge whether the balance between self-rule and shared rule is working well?
