The resolution commemorates the 175th anniversary of McLennan County, Texas, which was established on January 22, 1850, and named after pioneer Neil McLennan. The county, located in East Central Texas, spans 1,031 square miles and has a rich history that includes the presence of Native American tribes such as the Tonkawas, Wichita, Caddo, and Delaware before the arrival of Anglo settlers. The county's government was organized in August 1850, with Waco designated as the county seat. Significant developments in the late 19th century, including the construction of the Waco Suspension Bridge and the arrival of railroads, transformed Waco into a major trade center, with cotton as the leading industry.

As of 2023, McLennan County has a population of approximately 273,400 residents, with Waco being its largest city and home to various attractions, including the Texas Ranger Hall of Fame and Museum and Baylor University. The resolution expresses pride in the county's history and acknowledges the ongoing contributions of its communities to Texas's narrative. It extends best wishes for the future to the residents of McLennan County and calls for an official copy of the resolution to be prepared as a token of esteem from the Texas House of Representatives.
