What Is Federalism? How Power Is Divided Between Governments

What Is Federalism?

Federalism is a system of government in which power is constitutionally divided between a central (national or federal) government and regional governments (states, provinces, Länder, cantons, etc.), with each level having its own sphere of authority. Unlike a unitary state where the central government holds supreme power, or a confederation where regional governments retain supreme power, a federal system creates a genuine division of sovereignty between levels.

Federalism emerged as a compromise between two political extremes: the complete consolidation of power in a central authority (risking tyranny) and the fragmentation of sovereignty into fully independent states (risking disunity). The United States Constitution of 1789 created one of the earliest modern federal systems, drawing on earlier models including the Swiss Confederation (1291) and the Dutch Republic (1579). Today, approximately 25 countries — including the United States, Germany, Canada, Australia, India, Brazil, and Switzerland — operate under federal systems, collectively governing over 40% of the world's population.

Federal vs. Unitary vs. Confederal Systems

Evolution of American Federalism

American federalism has evolved through several distinct phases over more than two centuries:

• Dual Federalism ("layer cake" federalism, 1789–1930s): National and state governments operated as distinct sovereigns in separate spheres with minimal overlap. The 10th Amendment reserved non-delegated powers to states. Federal government focused on national defense, foreign policy, and interstate commerce; states handled most domestic affairs.
• Cooperative Federalism ("marble cake" federalism, 1930s–1960s): The New Deal and Great Society programs created intergovernmental cooperation, with federal grants funding state-administered programs. Federal and state governments shared responsibility for overlapping policy areas including welfare, transportation, and education.
• Competitive Federalism (New Federalism, 1970s–present): Beginning with Nixon and accelerating under Reagan, federal policy began emphasizing block grants (consolidated flexible grants replacing categorical grants) and returning power to states. Debate about the proper federal-state balance continues as a central feature of American politics.

Division of Powers: U.S. Model

The U.S. Constitution allocates powers in several categories:

• Enumerated (delegated) powers: Powers explicitly granted to the federal government (Article I, Section 8): collecting taxes, regulating interstate commerce, declaring war, coining money, establishing post offices, granting patents and copyrights
• Implied powers: Powers not explicitly stated but necessary and proper to carry out enumerated powers (Necessary and Proper Clause, Article I Section 8)
• Concurrent powers: Powers shared by both federal and state governments: taxation, spending, creating courts, building roads
• Reserved powers (10th Amendment): Powers not delegated to the federal government nor prohibited to states are reserved to states or the people. In practice, states have traditionally controlled education, criminal law, family law, land use, and most police powers.
• Prohibited powers: Actions forbidden to either federal or state government (e.g., states cannot coin money, enter treaties, or impair contract obligations)

Comparative Federalism: Germany and Australia

Federal systems vary considerably in how power is distributed and how the levels interact:

• German federalism (Basic Law, 1949): Germany's 16 Länder (states) have extensive administrative responsibilities but somewhat limited exclusive legislative powers. The national government (Bund) dominates legislation in most areas, while states primarily implement federal laws. The Bundesrat (Federal Council) represents state governments at the national level and must approve legislation affecting state interests. German federalism is often called "administrative federalism" because states implement most federal programs.
• Australian federalism (Constitution, 1901): Australia's six states retain significant powers, particularly in education, health, and criminal justice. The Commonwealth (federal government) has been steadily increasing its effective power through control of taxation (vertical fiscal imbalance: the Commonwealth collects most taxes but states spend most services). The High Court has generally expanded Commonwealth power over time.

Fiscal Federalism

Fiscal federalism studies how taxing and spending responsibilities are allocated across governmental levels. Key concepts include:

• Vertical fiscal imbalance: When one level of government (typically national) collects more revenue than it spends, while another level spends more than it collects, requiring transfers between levels
• Grants-in-aid: Transfers of funds from federal to state/local governments. Categorical grants must be used for specific purposes with conditions; block grants provide more flexibility within broad program areas
• Fiscal competition: States and localities compete for residents and businesses by offering favorable tax treatment and regulatory environments — the economic case for federalism as a "laboratory of democracy"

Federalism's defenders argue it provides laboratories for policy innovation (states can experiment before policies are adopted nationally), brings government closer to people, and protects against tyranny by diffusing power. Critics argue it creates inequality (residents of poor states receive inferior services), enables states to block progressive national policies, and creates inefficiency through duplicative government structures.
