The second World War greatly reshaped ideas about national identity in America, especially for first-generation immigrants, second-generation immigrants, and African-Americans. During the war - and in the midst of the war effort - immigrants and African-Americans were welcomed into the armed services and, also, in areas of production where support was needed. Many Americans, during this time, were able to somewhat relax or surrender their prejudices. Also, for immigrants and African-Americans, they often felt they were part of American industry and service for the first time.

1) Checks and Balances- This idea is implemented in the Constitution to ensure that no one branch of the federal government gains too much power. For example, the legislative branch(Congress) can approve a bill that will then be sent to the executive branch (President). If the president does not like the bill or thinks that it violates the rights of citizens, he/she can veto the bill. Vetoing the bill stops the bill from becoming a law. This check on power ensures that Congress makes laws that do not violate the rights of citizens.
2) Anti-Federalists do not want to ratify the Constitution unless it includes a Bill of Rights. The Anti-Federalists are worried that the Constitution gives too much power to the federal government. Having a strong central government caused problems when the US was still part of Great Britain. This is why the Anti-federalists are fearful of this type of system.
3) Federalists want a new constitution passed because it will fix America's weak political structure. Before the US Constitution is implemented, the constitution being used is known as the Articles of Confederation. This constitution has an extremely weak central government, allowing for disunity among the states.
Sharecropping, agricultural depression, the widespread infestation of the boll weevil, and flooding also provided motives for African Americans to move into the Northern Cities. The lack of social opportunities from Jim Crow laws also motivated African Americans to migrate Northward.
