Weaknesses inherent in the Articles of Confederation became apparent before the Revolution out of which that instrument was born had been concluded. Even before the thirteenth State (Maryland) conditionally joined the "firm league of friendship" on March 1, 1781, the need for a revenue amendment was widely conceded. Congress under the Articles lacked authority to levy taxes. She could only request the States to contribute their fair share to the common treasury, but the requested amounts were not forthcoming. To remedy this defect, Congress applied to the States for power to lay duties and secure the public debts. Twelve States agreed to such an amendment, but Rhode Island refused her consent, thereby defeating the proposal.

Thus was emphasized a second weakness in the Articles of Confederation, namely, the _liberum veto_ which each State possessed whenever amendments to that instrument were proposed. Not only did all amendments have to be ratified by each of the 13 States, but all important legislation needed the approval of 9 States. With several delegations often absent, one or two States were able to defeat legislative proposals of major importance.

Other imperfections in the Articles of Confederation also proved embarrassing. Congress could, for example, negotiate treaties with foreign powers, but all treaties had to be ratified by the several States. Even when a treaty was approved, Congress lacked authority to secure obedience to its stipulations. Congress could not act directly upon the States or upon individuals. Under such circumstances foreign nations doubted the value of a treaty with the new republic.

Furthermore, Congress had no authority to regulate foreign or interstate commerce. Legislation in this field, subject to unimportant exceptions, was left to the individual States. Disputes between States with common interests in the navigation of certain rivers and bays were inevitable. Discriminatory regulations were followed by reprisals.

Virginia, recognizing the need for an agreement with Maryland respecting the navigation and jurisdiction of the Potomac River, appointed in June 1784, four commissioners to "frame such liberal and equitable regulations concerning the said river as may be mutually advantageous to the two States." Maryland in January 1785 responded to the Virginia resolution by appointing a like number of commissioners[e] "for the purpose of settling the navigation and jurisdiction over that part of the bay of Chesapeake which lies within the limits of Virginia, and over the rivers Potomac and Pocomoke" with full power on behalf of Maryland "to adjudge and settle the jurisdiction to be exercised by the said States, respectively, over the waters and navigations of the same."[f]
