Explain the problem of dual sovereignty of the federal and state governments and how it was resolved

Also known as Dual Federalism, Dual Sovereignty is a system of political arrangement in which the state and federal governments have power divided between them in a way which does not interfere with each other. The federal government powers such as regulating the military forces, laying and collecting taxes, and coining money etc. while the state government exercises powers such as conducting elections and making banking, health, and criminal laws etc.

President Roosevelt, surrounding the Great Depression,  introduced a number of new policies like the New Deal policies which not only regulated commerce and economy, but policies like the Interstate Commerce Act in the Commerce clause gave Congress the authority to regulate commerce between state. This ensured that the state and federal governments would be working together more which eventually led to cooperative federalism in the United States.
