Mount Vernon Conference The Mount Vernon Conference was a 1785 meeting at Mount Vernon between delegates from Virginia (state) and Maryland convened to resolve navigational and commercial disputes on the Potomac River and Chesapeake Bay. The conference produced a compact that affirmed riparian rights, established inspection and quarantine regulations, and recommended broader interstate cooperation that influenced the Annapolis Convention and ultimately the Philadelphia Convention. The meeting brought together planter-politicians, jurists, and merchants whose local accord had national repercussions for the Articles of Confederation and the framing of the United States Constitution.

Background

Disputes over navigation, tolls, and jurisdiction along the Potomac River and tributaries intensified after the American Revolutionary War as states asserted competing claims stemming from colonial charters and colonial-era surveys. Merchants operating in the Chesapeake Bay and shippers using the Bay of Chesapeake faced differing regulations between Virginia (state) and Maryland, while land speculators tied to the Ohio Company of Virginia and interests in the Northwest Territory (United States) sought reliable interstate transit. Prominent figures such as George Washington—owner of the Mount Vernon estate—and commissioners from state legislatures recognized that unresolved tensions under the Articles of Confederation hindered commerce and posed hazards to revenue collected through navigation charges by local authorities.

Participants and Preparations

Delegates included commissioners appointed by the legislatures of Virginia (state) and Maryland, with notable participants drawing on experience in colonial assemblies, the Continental Congress, and state legislatures. Commissioners represented landed interests, shipping merchants, and legal authorities familiar with disputes previously arbitrated in colonial-era bodies like the House of Burgesses and later contested in state courts influenced by jurists associated with the Virginia Supreme Court of Appeals. Preparations involved surveying disputes referenced in colonial charters, mapping by surveyors trained under techniques linked to the work of Mason–Dixon line surveyors, and consulting precedents from compacts such as the Articles of Confederation and interstate negotiations previously attempted among the New England Confederation and other colonial alliances.

Proceedings and Agreements

Meeting at the Mount Vernon estate, commissioners negotiated a compact addressing navigation rights, harbor dues, quarantine measures, and administration of fisheries and ferry rights on the Potomac River and tributaries entering the Chesapeake Bay. Deliberations referenced legal principles found in colonial charters and decisions resonant with jurisprudence influenced by legal minds from the College of William & Mary and advocates who had sat in the Continental Congress. The final agreement established reciprocal privileges for citizens of both states, protocols for inspection of vessels, and joint management of improvements like canals and river clearing—measures aimed at facilitating trade between ports such as Alexandria, Virginia, Annapolis, Maryland, and Baltimore, Maryland. Commissioners resolved to forward their compact to the respective state legislatures and recommended reciprocity among other states, explicitly urging a broader convention to address deficiencies in the Articles of Confederation.

Significance and Aftermath

The Mount Vernon compact was ratified by the legislatures of Virginia (state) and Maryland and served as a practical model for interstate cooperation that contrasted with the limitations of the Articles of Confederation. Its success directly inspired delegates to call the Annapolis Convention (1786), where representatives from several states convened to propose a general revision of interstate commerce regulation; delegates from the Annapolis meeting subsequently endorsed calling the Philadelphia Convention (1787). The conference therefore occupies a causal link in the chain of events that culminated in the drafting of the United States Constitution, influencing debates over the federal regulation of commerce, navigation, and infrastructure.

Historical Legacy and Interpretations

Historians have treated the Mount Vernon Conference as an early example of pragmatic interstate federalism and as evidence of leading figures like George Washington exercising influential leadership outside formal office to mediate disputes. Scholarly interpretations vary: some emphasize the compact as a catalyst for constitutional reform alongside episodes such as Shays' Rebellion and the deficits revealed by the Articles of Confederation, while others situate it within regional efforts to coordinate commerce exemplified by later infrastructural projects such as canal-building tied to interests like the Chesapeake and Ohio Canal. Legal historians trace continuities between the conference's emphasis on riparian rights and later jurisprudence adjudicated by bodies including the Supreme Court of the United States after the adoption of the United States Constitution. The Mount Vernon Conference remains cited in studies of early American federalism, interstate compacts, and the pre-constitutional politics that shaped the emerging United States of America.
