Origins of Adams County

Early Native American Presence

Long before European settlers arrived, Adams County was inhabited by various Native American tribes. Archaeological evidence points to a vibrant prehistoric culture in the region, particularly the Adena and Hopewell tribes, who built numerous earthworks, mounds, and ceremonial structures. These indigenous cultures thrived between 1000 BCE and 500 CE, creating significant sites that can still be explored today, such as the Serpent Mound. These mounds, made from earth and stone, are believed to hold spiritual and astronomical significance, marking Adams County as an important site for Native American history.

The Founding of Adams County

Established on July 10, 1797, Adams County was one of the first counties created in Ohio. Named for President John Adams, the county was formed as settlers began moving westward from the original thirteen colonies. As the Northwest Territory opened for settlement, many Scotch-Irish, German, and English pioneers began establishing farms and communities in the area, leading to a growing demand for organized local governance. Early towns, such as West Union, emerged as hubs for these pioneers, and the county quickly established itself as an important agricultural region.

Early Settlements and Development

One of the earliest settlements in Adams County was Manchester, founded in 1791 by Nathaniel Massie, a Revolutionary War veteran and land surveyor. Manchester became an important trading post and river port along the Ohio River, drawing settlers with its fertile lands and access to water routes. As the population grew, West Union was established and chosen as the county seat in 1804 due to its central location. The construction of early roads and improved river access facilitated trade and agriculture, with corn, wheat, and livestock becoming essential to the economy.


Key Historical Events in Adams County

The War of 1812

Adams County played a significant role in the War of 1812, primarily due to its strategic location along the Ohio River. During the war, the county served as a key staging ground for American troops moving north to defend the Ohio Valley against British and Native American forces. Many residents of Adams County enlisted in the war effort, and their contributions helped secure the region and protect settlers from raids by Native American tribes allied with the British.

The Underground Railroad

In the decades before the Civil War, Adams County became a critical stop on the Underground Railroad, a network of secret routes and safe houses used by enslaved African Americans to escape to free states and Canada. The county’s location along the Ohio River provided a natural route for escapees, who were often assisted by local abolitionists. The town of West Union was known for its anti-slavery sentiment, and many residents risked their lives to help escaped slaves cross into free territory. Several homes and sites in Adams County, including the John T. Wilson Homestead, are believed to have served as safe houses during this period.

The Civil War Era

When the Civil War erupted in 1861, many residents of Adams County joined the Union Army, with the majority siding with the abolitionist cause. Adams County regiments participated in several significant battles, including the Battle of Shiloh and the Siege of Vicksburg. The county continued to support the Union war effort by providing soldiers, food supplies, and other resources. After the war, many veterans returned to Adams County and resumed farming, but the war’s effects were felt in the community for years to come.

Industrial Development in the 20th Century

As the United States industrialized in the late 19th and early 20th centuries, Adams County also experienced economic changes. The county, known for its rich natural resources, began to develop industries related to agriculture, such as canning and food processing, as well as small-scale manufacturing. Though Adams County never developed large urban centers, its industries contributed to the economy, creating jobs and maintaining the agricultural traditions of the region. The county’s small factories and local businesses helped sustain the economy, while the advent of railroads further facilitated trade and transportation of goods.
