Obion County, Tennessee, has a rich history that dates back to the prehistoric Native American inhabitants of the region. The first known tribes to settle in the area were the Chickasaw and Cherokee. European exploration and settlement began in the late 18th century when hunters and traders arrived from Virginia and North Carolina. However, the area remained largely rural and sparsely populated until the early 19th century.

The county was officially established in 1823, named after the Obion River, which flows through it. The county seat, Union City, was founded in 1854 and quickly became a thriving center for trade, commerce, and transportation. The arrival of the railroad in the late 19th century further stimulated economic growth in the area, allowing for the expansion of agriculture, industry, and commerce.

During the Civil War, Obion County was divided in its loyalties. Many residents supported the Confederacy, while others remained loyal to the Union. The county experienced several skirmishes and battles, including the Battle of Troy in March 1862. Following the war, the agricultural economy was heavily impacted, but the county recovered and saw a surge in industrial development in the early 20th century.

Today, Obion County is largely rural, with agriculture remaining a significant part of the local economy. The county is known for its rich farmland and is a major producer of cotton, soybeans, and corn. Industrial and manufacturing sectors have also grown, contributing to the county's economic diversity.
