Federalism is the backbone of American government, dividing power between national and state levels. This system balances central authority with local autonomy, promoting both unity and diversity across the nation.

The concept has evolved from early "dual federalism" to modern "cooperative federalism." This shift reflects changing interpretations of constitutional powers and the dynamic relationship between federal and state governments over time.

Federalism in the U.S. System

Definition and Core Principles

• Serves as a check on centralized power
• Provides multiple access points for citizen participation in governance

• Dual federalism ("layer cake federalism") describes early interpretation
  • Distinct and separate powers for federal and state governments
• Cooperative federalism ("marble cake federalism") emerged in 20th century
  • Emphasizes collaboration and overlapping responsibilities between federal and state governments
