The United States uses federalism, a system in which power is divided between the national government and the state governments. This division matters because it affects laws about taxes, schools, courts, elections, public safety, and daily life. Some powers belong mainly to the federal government, some belong mainly to the states, and some are shared by both.
Understanding these categories helps students see why different levels of government can act on the same issue.

Vocabulary
- Federalism
- Federalism is a system of government in which power is divided between a national government and state or regional governments.
- Concurrent Powers
- Concurrent powers are powers that both the federal government and state governments can legally exercise.
- Reserved Powers
- Reserved powers are powers kept by the states or the people because the Constitution does not give them to the federal government.
- 10th Amendment
- The 10th Amendment states that powers not delegated to the federal government are reserved to the states or to the people.
- Supremacy Clause
- The Supremacy Clause says that the Constitution and valid federal laws are the highest law of the land.
Common Mistakes to Avoid
- Calling all shared actions federal powers is wrong because concurrent powers can be used by both federal and state governments.
- Assuming reserved powers are listed one by one in the Constitution is wrong because the 10th Amendment protects powers not delegated to the federal government.
- Thinking state law always wins inside a state is wrong because valid federal law can override conflicting state law under the Supremacy Clause.
- Confusing reserved powers with denied powers is wrong because reserved powers may be used by states, while denied powers are powers governments are not allowed to use.
