A Weak National Government

The Articles of Confederation were conceived at the beginning of the Revolutionary War and ratified at its climax, so it's unsurprising that the former colonies were determined to never again fall under the thumb of a despot. Their solution was to reserve almost all power for the states. "Each state retains its sovereignty, freedom, and independence, and every power, jurisdiction, and right, which is not by this Confederation expressly delegated to the United States, in Congress assembled," the Articles proclaimed. The national government would have no executive or judicial branches. Any changes to the Articles required every state's assent, which made effecting any needed alterations nearly impossible.

From 1781 to 1787, the United States was governed by the Articles of Confederation. Under this system of government, the national legislature was granted very little power, with almost all sovereignty reserved for the individual states. The results were chaotic; there were breakdowns in commerce and security. In 1786, as the Articles' failure became increasingly clear, George Washington lamented, "What a triumph for the advocates of despotism to find that we are incapable of governing ourselves." These deficiencies led directly to the federal system encapsulated in the Constitution
