Trinity County, Texas, was established on August 11, 1850, and named after the Trinity River that flows through the region. The native Karankawa, Caddo, and Atakapa tribes inhabited the area for thousands of years before European settlers arrived. In the early 19th century, Stephen F. Austin's colonists began to settle in the Trinity River Valley, establishing communities such as Trinity, Pennington, and Groveton, which served as trading posts for fur trappers and pioneers.

During the Civil War, Trinity County, like other parts of Texas, was predominantly pro-Confederate. The county contributed soldiers to the Confederate Army and faced several Union invasions. After the war, Trinity County faced economic challenges due to the loss of slavery and the devastation of crops and infrastructure. However, the discovery of lumber and the expansion of railroads in the late 19th century revitalized the local economy.

The timber industry became a major economic force in Trinity County during the late 1800s and early 1900s. Several sawmills were built, attracting workers and leading to the emergence of towns like Apple Springs and Pennington. Logging became a vital industry, with timber being transported via the railroads to markets across Texas and beyond. However, unsustainable logging practices eventually led to a decline in the industry, and today, forestry remains an important aspect of the county's economy.

In recent years, Trinity County has embraced its natural resources, including its pristine rivers, lakes, and forests, to develop tourism and recreational opportunities. Outdoor activities like fishing, hunting, boating, and hiking attract visitors from across the state. The county's rich history, marked by its Native American heritage, the Civil War era, and the lumber industry, is preserved in museums and historic sites, providing a glimpse into Trinity County's past.
