Featured Topic: Separation of Powers

The separation of powers is a fundamental principle of American government, dividing authority among three branches to prevent any single entity from becoming too powerful.

▼

The legislative branch, consisting of the House of Representatives and the Senate, is responsible for making laws. Key powers include:

  • Passing legislation
  • Declaring war
  • Regulating commerce
  • Impeachment power
  • Confirming executive appointments

The House has 435 members apportioned by state population, while the Senate has 100 members (2 per state).

Executive Branch (President)

▼

The executive branch, led by the President, is responsible for implementing and enforcing laws. Key powers include:

  • Serving as Commander-in-Chief
  • Appointing federal officials
  • Negotiating treaties
  • Vetoing legislation
  • Issuing executive orders

The President serves a four-year term and can be elected to a maximum of two terms.

Judicial Branch (Supreme Court)

▼

The judicial branch, headed by the Supreme Court, interprets laws and determines their constitutionality. Key powers include:

  • Judicial review
  • Interpreting federal laws
  • Resolving disputes between states
  • Protecting constitutional rights
  • Serving as the final court of appeals

The Supreme Court consists of nine justices who are appointed for life by the President and confirmed by the Senate.
