The two major weaknesses of the national government under the Articles of Confederation were its lack of taxation power and its lack of authority over interstate and foreign commerce. Congress could request money from the states but could not compel payment, and it could not regulate trade among the states or with other nations. Each weakness created problems because the national government could not fund its debts or defense, and the states pursued conflicting trade policies that fragmented the economy. Those failures, visible in the 1780s, drove the 1787 Constitutional Convention.
The requisition mechanism and why it failed
The Articles of Confederation, ratified in March 1781, created a "league of friendship" among thirteen sovereign states. Congress had no independent revenue stream. Its only fiscal tool was the requisition: a formal request that states contribute a quota to the national treasury, apportioned roughly by real property value.
The mechanism had no enforcement step. No national tax collector existed, no court could compel a delinquent state, and Congress could not levy tariffs, duties, or excises. States paid when they chose to, and many chose not to.
The consequences compounded. Congress borrowed heavily during the Revolutionary War, and loan certificates circulated as promises of future payment. Without revenue, those promises lost credibility. Officers of the Continental Army went unpaid, and in 1783 a group of them pressured Congress directly. By the mid-1780s the national government was functionally insolvent. A government that cannot collect money cannot borrow cheaply, pay soldiers, or honor treaties that require funding.
The requisition problem in quantified context
The numbers are stark. In March 1781, Congress requisitioned USD 10 million from the states for the year. Total payments received fell far short of that figure, and arrears accumulated for years. By the end of 1782, collections remained a fraction of what was owed.
The debt picture was worse. Robert Morris, the Superintendent of Finance from 1781 to 1784, estimated the national debt at roughly USD 40 million, including foreign loans from France and the Netherlands and domestic obligations to soldiers and suppliers. Without tax power, Morris resigned in 1784, and the treasury department effectively wound down.
Amending the Articles required unanimous consent of all thirteen state legislatures. Congress proposed an impost, a 5 percent duty on imported goods, in 1781 and again in 1783. Both times, one state legislature blocked ratification, killing the measure. That unanimity threshold meant any single state could veto national revenue.
Why commerce fragmentation strangled the economy
The commerce weakness was structural, not accidental. Under the Articles, Congress could coin money and regulate its value, but it could not regulate interstate commerce or foreign commerce. Each state ran its own trade policy.
The result was a patchwork. States imposed tariffs and duties on goods crossing their borders, including goods from neighboring states. New York taxed imports that passed through its port, collecting revenue at the expense of Connecticut and New Jersey merchants. States issued their own paper money and legal-tender laws, and a debt contract in one state might be settled in depreciated currency in another.
Foreign policy suffered too. Congress could negotiate treaties, but it could not enforce commercial terms because it could not regulate trade. Britain restricted American shipping to the British West Indies after the war, and the national government had no retaliatory trade power to negotiate with. Spain closed the Mississippi River to American navigation in 1784, and western settlers could not rely on national authority to reopen it. A single national trade policy was impossible when thirteen states each guarded their own ports.
Concrete numbers illustrate the stakes. American exports to Britain fell sharply after independence as British navigation laws excluded American ships from imperial trade routes. State tariff schedules differed in rates and covered goods, so merchants faced unpredictable costs at every border crossing. The economy contracted in the mid-1780s, and debt-heavy farmers in western Massachusetts revolted in 1786 in Shays' Rebellion, an event that made the national government's weakness visible to elites.
Edge cases and contradictions
The Articles were not simply a failure of will. They reflected a deliberate revolutionary suspicion of centralized power, and some founders saw state sovereignty as a feature, not a bug.
Rhode Island's refusal to approve the impost is the classic example. A small state with a major port, Rhode Island benefited from import duties it collected itself. Its legislature blocked national revenue repeatedly. The same logic applied to New York, which profited from taxing goods bound for neighboring states.
Another counterintuitive detail: the Articles government did achieve some notable successes. The Land Ordinance of 1785 created a systematic survey and sale system for western territory, and the Northwest Ordinance of 1787 established governance rules and prohibited slavery in the territory north of the Ohio River. Those achievements show a functioning Congress in areas where it had clear authority — territory and surveying — and total paralysis where it did not. The failure was specific to revenue and commerce, not universal.
Weakness comparison at a glance
| Feature | Under the Articles | Under the Constitution (1789) |
|---|---|---|
| Tax authority | Requisitions to states only; no enforcement | Congress levies taxes and duties directly |
| Commerce power | None over interstate or foreign trade | Regulates interstate and foreign commerce |
| Currency | Congress coins money; states issue their own | National currency standard; states barred from coining |
| Amendment threshold | Unanimous consent of thirteen states | Two-thirds of Congress and three-fourths of states |
| Enforcement of law | No national courts of general jurisdiction | Federal judiciary with appellate authority |
| Military funding | State quotas and requisitions | Congressional power to raise and support armies |
The table compresses a four-decade shift. The Constitution did not just add powers; it moved the enforcement point from state legislatures to the national government.
Timeline of the failure cascade
| Date | Event | Fiscal or commercial impact |
|---|---|---|
| March 1781 | Articles ratified | Requisition system becomes the only revenue mechanism |
| 1781 | First impost of 5 percent proposed | Blocked by a single state; no national duty |
| 1782 | Collections of 1781 requisition tallied | Payments fall far short of the USD 10 million quota |
| 1783 | Second impost proposed | Blocked again; national revenue remains elusive |
| 1784 | Robert Morris resigns as Superintendent of Finance | Treasury operations shrink; debt unpaid |
| 1784 | Spain closes Mississippi to American navigation | Western trade strangled; no national leverage |
| 1786 | Shays' Rebellion in Massachusetts | Demonstrates inability to fund or enforce order |
| 1787 | Constitutional Convention convenes | Framers design taxation and commerce powers |
Misconceptions about the Articles
A common misconception is that the Articles created no national government at all. They did create a Congress with diplomatic, military, and territorial authority, and it functioned in those domains.
Another misconception is that the failures were purely political failures of leadership. The weaknesses were structural. Even a brilliant Congress could not collect a requisition it had no power to enforce, and it could not negotiate a trade treaty it could not implement. The framers of the Constitution diagnosed the mechanism, not the personnel.
A third misconception conflates the two weaknesses. Taxation and commerce failed through different channels. Tax failure was a compliance problem: states simply did not pay. Commerce failure was a coordination problem: states actively competed. The fixes differed too. The Constitution gave Congress direct taxing power and a commerce clause that preempted state trade barriers.
A professional caveat: historians debate how severe the 1780s economic crisis actually was. Some scholarship suggests the depression was uneven across regions and that the Articles government worked better than nationalist rhetoric claimed. The structural weaknesses remain undisputed, but the degree of crisis is contested.
Practical signals for spotting a weak central authority
If you are studying constitutional design or evaluating a decentralized system, these are the red flags that map onto the Articles failure:
Warnings: Revenue depends on voluntary contributions from member units, with no enforcement mechanism. Warnings: Member units impose tariffs or barriers on each other's goods, fragmenting a single market. Warnings: Amendment requires unanimity, giving any single unit veto power over collective action. Warnings: The center can sign agreements but cannot implement or fund them. Warnings: Currency issuance is decentralized, with competing legal-tender laws. Warnings: Defense funding depends on quotas that members honor inconsistently.
Each warning describes a specific channel through which authority leaks from the center to the periphery. The Articles had all six.
Practical actions for evaluating or designing a system
Start by tracing the revenue chain. Ask whether the center can collect money directly or must request it, and identify who can block the request. Trace the commerce chain next: can the center override local trade barriers, and does a single market exist in practice? Check the amendment threshold and ask which single actor can veto change. Then test enforcement: can the center fund its obligations and honor its agreements? For each of the six warnings above, assign a concrete threshold, such as a share of revenue that must be voluntary, and reconcile those thresholds explicitly rather than treating them as independent. Finally, distinguish mechanism from personnel: a well-run weak system is still weak.
Limitations and what this explanation leaves out
This explainer focuses on the two weaknesses named in the question, so it understates other Articles problems, including the absence of a national judiciary, the lack of a chief executive, and the difficulty of raising an army. Those failings interacted with the fiscal and commercial weaknesses, and the Constitution addressed all of them together. No single defect caused the 1787 Convention. The fiscal and commercial flaws were the most visible, and they supplied the political momentum. Historians continue to debate how much of the crisis was structural versus contingent, and the evidence supports the structural reading for these two mechanisms specifically.
