The Story
# First Ohio Company Settlers Arrive at the Confluence
The American Revolution was fought not only for independence from Britain but also for the promise of what lay beyond the Appalachian Mountains. For the soldiers who endured years of hardship in the Continental Army, often receiving little or no pay for their service, the vast lands of the Ohio Country represented both compensation owed and a future earned. It was this promise that drove Brigadier General Rufus Putnam, a skilled military engineer who had served under George Washington, to organize one of the most ambitious settlement ventures in American history through the Ohio Company of Associates. Founded in 1786 by Putnam and other New England veterans, the company negotiated the purchase of approximately 1.5 million acres along the Ohio River from the federal government, which had gained control of the territory through the Treaty of Paris in 1783. The Northwest Ordinance of 1787, which established a framework for governing these western lands and eventually admitting new states to the union, provided the legal architecture that made organized settlement possible. With land secured and a government structure in place, Putnam assembled a party of pioneers to make the dangerous journey westward.
On April 7, 1788, the first group of Ohio Company settlers — forty-eight men, most of them veterans of the Revolutionary War — arrived at the confluence of the Ohio and Muskingum Rivers in what is now southeastern Ohio. They had departed from Pittsburgh aboard a large flatboat they christened the *Mayflower*, a deliberate and symbolic reference to the Pilgrim vessel that had carried English settlers to Plymouth in 1620. By choosing this name, Putnam and his companions cast themselves as founders of a new civilization, extending the arc of American settlement from the Atlantic coast into the heart of the continent. Among the settlers was Israel Putnam, who shared in the company's vision of building a structured and orderly community in the wilderness. Awaiting their arrival was Brigadier General Josiah Harmar, whose federal troops had been stationed at the confluence to provide military protection and to receive the incoming pioneers.
The settlers wasted no time in establishing their community. They named their settlement Marietta in honor of Marie Antoinette, the Queen of France, a gesture of profound gratitude for the French alliance that had proven decisive in securing American independence. Without French military support, financial aid, and naval power — most critically at the Battle of Yorktown in 1781 — the outcome of the Revolution might have been very different, and the naming of Marietta stood as a lasting acknowledgment of that debt. Later that year, General Arthur St. Clair, a Continental Army veteran who had fought at Trenton, Princeton, and Brandywine, arrived at Marietta to assume his role as the first governor of the Northwest Territory. His presence transformed the settlement from a frontier outpost into the official seat of government for a territory that encompassed the future states of Ohio, Indiana, Illinois, Michigan, and Wisconsin. Marietta thus held the distinction of being both the first permanent American settlement in the Northwest Territory and its political capital.
The founding of Marietta was not merely a footnote to the Revolution; it was among its most consequential outcomes. The war had been fought to secure self-governance and opportunity, and the settlement at the confluence represented the physical realization of those ideals. Pioneers like Persis Rice Putnam, who would later join the community as one of its early female settlers, helped transform a military encampment into a lasting home, enduring the considerable dangers of frontier life, including conflict with Indigenous nations who had their own deep claims to the land. The arrival of those forty-eight men on the *Mayflower* in April 1788 set in motion the westward expansion of the young republic, proving that the Revolution's consequences would extend far beyond the battlefields of the East. Marietta became a model for ordered settlement under federal law, a place where the sacrifices of war were converted into the foundations of a new American society.
People Involved
Brigadier General Rufus Putnam
Continental Army Engineer
Massachusetts engineer officer who served as the Continental Army's chief engineer and designed the fortifications at Boston and West Point. Founded the Ohio Company of Associates with Manasseh Cutler, led the first settlers to Marietta in April 1788, and designed Campus Martius. Served as Surveyor General of the United States under Washington.
General Arthur St. Clair
Continental Army General
Pennsylvania-born Continental Army general who served as President of the Continental Congress before becoming the first Governor of the Northwest Territory in 1788. He established his territorial government at Marietta, creating the legal and administrative institutions the Northwest Ordinance required. His 1791 military defeat by a confederacy of Native nations was the worst American military defeat by Native forces in the nation's history.
Israel Putnam
Ohio Company Settler
Nephew of Revolutionary War General Israel "Old Put" Putnam who settled in Marietta with the original Ohio Company group. He served as a ranger and scout during the frontier war years, operating between Campus Martius and the outer settlements. His connection to his famous uncle linked Marietta symbolically to the Revolutionary War generation that had founded it.
Persis Rice Putnam
Pioneer Settler
Wife of Rufus Putnam and one of the women who helped establish domestic and community life at Marietta. The Putnam household at Campus Martius became a center of the settlement's social life. Women of the founding generation managed homes, gardens, and children through years of frontier isolation and periodic warfare, making the survival of the community possible.
