Final answer:
The main differences between the views concerning the ratification of the Constitution lay between the Federalists, who favored a stronger national government, and the Anti-federalists, who wanted to preserve state powers and demanded a Bill of Rights.
Step-by-step explanation:
The differences between the views on the ratification of the Constitution are primarily between the Federalists, who supported a stronger national government, and the Anti-federalists, who believed the Constitution granted too much power to the national government at the expense of the states. Leading Federalists like James Wilson advocated for ratification because they saw the strengthening of the national government as essential for the survival and growth of the union, envisioning it would encourage commerce and business activity. Anti-federalists such as Patrick Henry opposed these centralized powers, advocating for state rights, and were concerned about the potential for tyranny in the new government structures. The need for a Bill of Rights was a pivotal issue that nearly derailed ratification, leading to guarantees that the rights would be added through amendments to garner support from larger states.
