The area now known as Williamson County has attracted humans for over 13,000 years. The Tonkawa Indians called the area takachue pouetsu, which means "land of good water." In 1848, the Texas Legislature carved a county out of a southwestern portion of the Milam District. They named it after Robert McAlpin Williamson, a judge, lawmaker, and Battle of San Jacinto veteran who was widely known as "Three-legged Willie." Just as the Native Americans before them, settlers were drawn to the area for its abundant water and fertile soil, and the population quickly grew. While agriculture has been a driving force behind the local economy for decades, the county has witnessed a shift from the small farmer and rancher to the larger agribusiness. In addition, Williamson County is a center for education and the high-tech industry and is home to institutions and companies including Southwestern University, the Round Rock Higher Education Center, and Dell.
