Federalism, one of the most important and innovative concepts in the US Constitution, refers to the constitutional division of power between the federal government and individual state governments. The US Constitution is underpinned by the tensions between the federal government and the states, with the former having gradually accrued more power since the country's founding. Federalism was a response to the weak federal government under the Articles of Confederation, which gave most of the power to the states. The Constitutional Convention of 1787, which debated the structure and limitations of federalism, resulted in the US Constitution and the federal democratic republic system of government in place today. The Constitution's federal system created a unique solution to sharing power between the states and the national government, with the Tenth Amendment explicitly recognising the powers of state governments.

The evolution of federalism since the Constitution was ratified in 1788
Federalism in the United States has evolved significantly since the Constitution was ratified in 1788. The Constitution, which replaced the Articles of Confederation, established a federal system of government with a division of powers between the federal government and the individual state governments. This system aimed to balance centralised and decentralised governance, ensuring a powerful central government while preserving the liberty of the governed.
In the early years of the Constitution, federalism took the form of dual federalism, with a clear division of powers between the federal and state governments. However, this balance shifted over time, with the national government gradually gaining more power. The Fourteenth Amendment, enacted after the Civil War, placed new constraints on state governments, with the federal government now able to prevent states from violating the privileges and immunities of their citizens. The period between 1819 and the 1860s further demonstrated the national government's growing role, often provoking resistance from the states seeking to protect their interests.
The evolution of federalism in the United States has also been characterised by shifts in intergovernmental relations and the expansion of federal regulations. The Necessary and Proper Clause of the Constitution grants Congress the power to make laws necessary for executing its enumerated powers, with broad interpretations allowing for increased federal authority. The Commerce Clause, empowering Congress to regulate commerce among the states, has been a subject of debate, with varying interpretations influencing the balance of power between the federal and state governments.
The Supreme Court has played a significant role in defining the relative powers of the federal and state governments. Landmark cases such as McCulloch v. Maryland (1819) and Gibbons v. Ogden (1824) helped establish the principle of national supremacy and settled power struggles between the states and the national government. The Court's interpretations and rulings on federalism-related issues continue to shape the evolution of federalism in the United States.
Federalism in the United States has evolved through different historical phases, adapting to the nation's political, social, and economic changes. The basic structural characteristics of the system, however, have endured, reflecting the country's early political development and the desire to balance centralised and decentralised governance.

The Tenth Amendment and the police power
Federalism in the United States refers to the division of power between the federal government and individual state governments. The US Constitution, ratified in 1788, replaced the Articles of Confederation, which was essentially a treaty among sovereign states. The Constitution established a federal democratic republic system of government, with a powerful central government while preserving the liberty of the governed.
The Tenth Amendment, which states that "the powers not delegated to the United States by the Constitution, nor prohibited by it to the states, are reserved to the states respectively, or to the people", is central to federalism. This amendment explicitly outlines the states' broad regulatory power and general police power to create and enforce laws within their borders.
Police power is exercised by the legislative and executive branches of state governments through the enactment and enforcement of laws and regulations. States have the authority to compel obedience to these laws through various measures, provided they do not infringe upon the rights protected by the US Constitution or their own state constitutions. The police power is derived from English and European common law traditions and is justified by two Latin principles: "sic utere tuo ut alienum non laedas" ("use that which is yours so as not to injure others") and "salus populi suprema lex esto" ("the welfare of the people shall be the supreme law").
The police power of states has been expanded and clarified through various court cases, including Commonwealth v. Alger in 1851 and Jacobson v. Massachusetts in 1905. The broad regulatory power of states, derived from the Tenth Amendment, has been recognised in modern jurisprudence, such as in the 2019 California Supreme Court case T-Mobile, LLC v. City and County of San Francisco.
The Fourteenth Amendment, enacted after the Civil War, placed new federal constraints on state governments, forbidding them from violating the fundamental rights of their citizens. This amendment further shaped the dynamic between federal and state powers, with Section 5 granting Congress the power to enforce these constraints.

The benefits of federalism
Federalism, enshrined in the US Constitution, refers to the division of power between the federal government and individual state governments. This division of power has several benefits:
Political Participation
Federalism encourages political participation by creating two levels of government capable of taking action. If a policy goal fails to secure support at one level, it can be brought before elected representatives at another level. This encourages individuals, groups, and social movements to actively participate and help shape public policy.
Policy Innovation
The US Constitution's federalist structure empowers states to act as "laboratories of democracy", according to Supreme Court Justice Louis Brandeis. States can harness their constitutional authority to innovate policies that might eventually be adopted at the national level. For example, many New Deal breakthroughs, such as child labor laws, drew inspiration from state-level policies.
Diversity of Opinion
Federalism accommodates diverse viewpoints across the country. It allows for the representation of varying regional, cultural, and ideological perspectives in policymaking. This diversity of opinion helps to prevent a singular ideology or perspective from dominating the entire nation.
Checks and Balances
Federalism enables separate governments to check each other's power. As Alexander Hamilton wrote in The Federalist No. 28, "Power being almost always the rival of power... if their rights are invaded by either [state or federal government], they can make use of the other as the instrument of redress." This system of checks and balances helps maintain a balance of power and protect citizens' rights.
Unity and Regional Self-Governance
Federalism can also help prevent national dissolution by allowing regions a degree of self-governance. For example, Belgium may have avoided partition by granting Flanders extensive self-governance, and Sardinia likely avoided a violent separatist movement by securing significant autonomy within Italy. Federalism can thus be a tool for preserving national unity while accommodating regional diversity.

The Anti-Federalist critique
Anti-Federalism was a political movement in the late 18th century that opposed the creation of a stronger US federal government and the ratification of the 1787 Constitution. Led by Patrick Henry of Virginia, Anti-Federalists believed that the Constitution would lead to a loss of individual liberties, an erosion of state sovereignty, and the potential rise of tyranny. They advocated for a more decentralised form of government with greater protections for individual rights and stronger state representation.
Anti-Federalists were concerned that the national government would become too powerful and threaten states' and individuals' rights. They believed that the Constitution, as written, would be oppressive and consolidate too much power in Congress, at the expense of the states. They saw the unitary executive as resembling a monarchy and feared that it would eventually produce courts of intrigue in the nation's capital.
Furthermore, Anti-Federalists believed that a large central government would not serve the interests of small towns and rural areas, unlike the urban interests that most Federalist delegates aligned with. They argued that the liberties of the people were best protected when power resided in state governments rather than a federal one. Anti-Federalists also believed that the federal government's powers to tax, as provided by the Constitution, could be used to exploit citizens and weaken the power of the states.
The Anti-Federalists mobilised against the Constitution in state legislatures across the country, particularly in Massachusetts, Virginia, and New York, where ratification was made contingent on a Bill of Rights. Their arguments influenced the formation of the Bill of Rights, and the Federalists agreed to consider amendments to be added to the new Constitution. James Madison, a Federalist and the primary architect of the Constitution, introduced draft proposals that became the first ten amendments, including the Tenth Amendment, which reinforced the reservation of powers to the states or the people.

The Necessary and Proper Clause
Federalism in the US Constitution refers to the division of power between the federal government and individual state governments. The US Constitution, ratified in 1788, replaced the Articles of Confederation, which was essentially a treaty among sovereign states. The Constitution was created to form a powerful central government while preserving the liberty of the governed.
The landmark Supreme Court case McCulloch v. Maryland (1819) interpreted the Necessary and Proper Clause as granting implied powers to Congress in addition to its enumerated powers. The Court ruled that Congress had the implied power to establish a bank, as it was a suitable instrument to aid in Congress's power to tax and spend. This case set a precedent for a broad interpretation of "necessary," with the Court siding with Hamilton's view that legislation reasonably related to express powers was constitutional.
