The Treaty of Paris of 1783 is presented in the essays as a measure of national credibility and a fragile instrument of union: its obligations expose the Confederation’s inability to secure compliance, while the settlement of western lands associated with it offers a practical reason for the states to remain together. The treaty therefore carries two linked meanings—an international commitment whose breach invites danger, and a compact whose benefits depend on continued federal cooperation.

A test of national credibility

The essays treat treaty observance as a matter of public safety, not merely diplomatic form. Under a single national government, treaties and the law of nations would, they argue, be interpreted consistently and executed in one manner. Separate state courts and judges, shaped by different local laws and interests, might instead reach conflicting decisions on the same questions. A central authority would also be less exposed to the immediate local advantage that might tempt a state’s governing party to abandon good faith; national institutions could prevent or punish violations that a state government, even if willing, lacked the power to stop.

The peace treaty with Britain gives this reasoning particular force. The essays point to the country’s failure to honor its own commitments as a reason it could not remonstrate with dignity when Britain continued to hold valuable territories and important posts that, under express treaty stipulations, should already have been surrendered. The treaty thus makes the Confederation’s weakness visible in both directions: the United States could not reliably perform its obligations, and it could not compel the other party to perform its own.

Western lands and the Union’s settlement

The treaty also forms part of the argument over western territory. The essays describe competing state claims to lands that had been ungranted at the Revolution, often called crown lands. Some states claimed the lands because they lay within their former colonial boundaries; others argued that the rights of the British Crown had passed to the Union. That latter claim was especially associated with the western territory that had been under British jurisdiction, whether through possession or the submission of Indigenous proprietors, until its relinquishment in the peace treaty. The essays characterize the acquisition as secured for the Confederacy through agreement with a foreign power.

Congress had sought to quiet the dispute by persuading states to cede claims to the United States for the benefit of the whole. Continued union, the essays contend, offered a clear prospect of settling the controversy amicably. Dissolution could reverse that progress: states that had ceded land as a federal compromise might seek to reclaim it once the purpose of the grant disappeared, while other states would claim a share on the ground that the territory had been acquired or secured through the Confederacy’s joint efforts. Even if all accepted a common right to the lands, they could still disagree over how to divide them, since different rules of apportionment would serve opposing interests.

Disunion, conflict, and the treaty’s warning

The treaty’s troubled aftermath belongs to a wider warning against expecting peace among neighboring states after separation. The essays recall that the country had already suffered from lax administration, disputes, and declining national credit; they argue that disunion would expose the states to conflicts over territory and to temptations to violate agreements for immediate local gain. In this account, a general government insulated from any one state’s circumstances is better placed to preserve good faith and prevent local disputes from becoming causes of war.

The treaty’s significance is consequently double-edged. It records a peace made with a foreign power, but its provisions also reveal how little a government can guarantee when it cannot secure its own obligations, protect national rights, or maintain a settlement among its members. The essays use that contrast to make the case for union: without common authority, both international credibility and the domestic compromises that sustain it remain vulnerable.
