Final answer:
The Constitution of 1787 centralized power in a strong national government as opposed to the Articles of Confederation, which favored state sovereignty and a weaker federal government.
Step-by-step explanation:
Compared with the Articles of Confederation, the Constitution of 1787 centralized power in a strong national government. Under the Articles, the federal government was quite weak relative to the states. However, the U.S. Constitution introduced a new framework that created a government that was both national and federal. This new structure increased the power of the central government while also recognizing the individual states as enduring entities.
