The first permanent U.S. settlement in the Northwest Territory

In short: Before Ohio was a state, it was the Northwest Territory—a vast expanse of land with complex history. In 1788, pioneers established Marietta as the region's first official foothold. Named for a French queen but built by New Englanders, this city sits atop a prehistoric landscape that predates modern America by millennia.

Marietta was founded on April 7, 1788, by 48 men from the Ohio Company of Associates. These settlers were primarily "Yankees"—descendants of Puritan English colonists from New England. They chose the confluence of the Muskingum and Ohio Rivers because a survey by geographer Thomas Hutchins labeled it the best part of the western country. The settlement was named in honor of Marie Antoinette, reflecting the era's gratitude for French aid during the American Revolution.

The site holds deep historical layers. Long before European arrival, the Hopewell culture inhabited the area between 100 BC and AD 500. They constructed the Marietta Earthworks, a complex featuring platform mounds for ceremonies and elite residences, as well as large conical burial mounds. While early settlers preserved some of these monuments—such as the Great Mound (Conus)—for their own cemetery, other features like the Sacra Via path were destroyed during 19th-century development.

The city's history is also marked by conflict and industrial growth. Following the Revolutionary War, the U.S. government used land warrants to pay veterans, leading to increased tensions with Indigenous tribes. Despite a 1789 treaty intended to settle trade and boundaries, settlers pushed into tribal lands, eventually leading to their defeat in the mid-1790s. By the 1800s, Marietta became an industrial hub, producing everything from oceangoing vessels and steamboats to iron rails for the burgeoning railroad industry.

Marietta also served as a center for social progress and education. It was home to numerous abolitionists; in 1802, state delegate Ephraim Cutler helped sway the vote to make Ohio free of slavery. The city's first church, chartered in 1799, remains the longest continuously worshiping congregation west of the Alleghenies. Additionally, Marietta College served as a station on the Underground Railroad, providing a literal path to freedom for enslaved people seeking escape from the South.
