Austin’s educational foundations were laid in the late 19th century. In September 1881, the city held its first public school classes, and Tillotson Collegiate and Normal Institute (now part of Huston–Tillotson University) opened the same year. The University of Texas at Austin held its first formal classes in 1883, though instruction had already begun in the original wooden state capitol.

The 1880s brought new prominence to Austin as the Texas State Capitol was completed in 1888, claiming the title of the world’s seventh-largest building. During this period, the city expanded its boundaries to more than triple its original size. Early infrastructure projects included the construction of the first granite dam on the Colorado River to power streetcars and the iconic “moon towers,” though the dam was destroyed by flooding in 1900.

Civic development continued through the 1920s and 1930s with the implementation of the 1928 Austin city plan, funded in part by the Public Works Administration. The establishment of the Lower Colorado River Authority (LCRA) enabled the creation of the Highland Lakes system, including the replacement of the granite dam with a hollow concrete dam forming Lake Austin and the Mansfield Dam upstream creating Lake Travis for flood control.

Despite economic growth, Austin experienced a three-way system of racial segregation between Anglos, African Americans, and Mexicans, with housing deed restrictions and segregated public services reinforcing inequality through the first half of the 20th century.

Austin initially missed out on the Texas Oil Boom’s prosperity, causing its rank among Texas cities to drop from fourth to tenth between 1880 and 1920. After recovery from the Great Depression, the city emerged as a major metropolitan center, establishing a foundation for modern growth. By 1970, Austin was 14.5% Hispanic, 11.9% Black, and 73.4% non-Hispanic white.

The late 20th century marked Austin’s rise as a national cultural and technology hub. The city became a center for high-tech industries, including semiconductors and software, while the University of Texas grew in prominence. Simultaneously, Austin’s music scene flourished with artists like Willie Nelson, Stevie Ray Vaughan, and Asleep at the Wheel, alongside legendary venues such as the Armadillo World Headquarters. Iconic events and programs such as Austin City Limits, the Austin City Limits Festival, and the South by Southwest (SXSW) festival cemented Austin’s reputation as the “Live Music Capital of the World.”
