In its first government after the American Revolution, why did the United States establish a weak national government?

1 The states were jealous of one another.
2The delegates could not agree upon a plan of government.
3 The states had experienced problems under a strong monarchy.
4The delegates had more allegiance to their states than to a new nation.

All of the given options played a role in the United States establishing a weak national government in its first government after the American Revolution. However, option 4 is the most accurate reason. The delegates at the time had a stronger allegiance to their individual states rather than to a new nation. This loyalty to their respective states made it challenging for them to agree upon a plan of government that would give substantial power to a central or national authority. As a result, they opted for a weaker national government that would ensure the states retained a significant degree of power and autonomy.
