The first successful experimental farm in the United States was established in Indiana in 1862. Known as the Purdue University Agricultural Experiment Station, it paved the way for modern agricultural practices.

Ohio County, Indiana is located on the southeastern border of the state, nestled along the banks of the Ohio River. The county was officially established on March 1, 1844, making it one of the later counties to be formed in the state. Prior to its establishment, the land that would become Ohio County was largely wild and untamed, inhabited by Native American tribes such as the Miami and Delaware.

The early settlement of Ohio County was marked by pioneers who ventured westward, seeking fertile land for farming and opportunities for trade along the river. These settlers faced numerous challenges, including harsh winters and occasional flooding. However, they persevered and started establishing small farming communities, churches, and schools.

One of the key events in the history of Ohio County was the construction of the Ohio & Mississippi Railroad in the mid-19th century. This railway connected Cincinnati to St. Louis, passing through Rising Sun, the county seat of Ohio County. The rail line brought improved transportation access to the area, fueling economic growth and attracting new businesses.

Over the years, Ohio County has continued to evolve and adapt to changing times. Agriculture has remained an integral part of the county's economy, with farmers cultivating crops such as corn, soybeans, and tobacco. The county has also seen industrial development, particularly in pharmaceuticals and manufacturing. Today, Ohio County is known for its scenic beauty, historic architecture, and vibrant riverfront community.
