As the capital of Texas, Austin has a long and colorful history. The first residents were nomadic Native Americans who camped here as long ago as 9000 BC because of the area's beauty, the clear Colorado River, and the wildlife. These are the very same things that attract people to Austin today. Originally called Waterloo, Austin has grown from a tiny town on the edge of the western frontier in 1839 into the capital city it is today. The University of Texas lent prestige, the state government erected buildings, the railroads came to town, and Congress Avenue—the main street of Texas—filled with thriving businesses.
