History
Falls City was established as a rural community in Karnes County during the late 19th century, growing as settlers moved into South Texas to take advantage of the fertile ranchland and agricultural opportunities the region offered. The area's economy was historically driven by cattle ranching and farming, and the community developed around the social and commercial needs of surrounding rural families. In more recent decades, the discovery and production of oil and gas in the Eagle Ford Shale formation beneath Karnes County brought renewed economic activity to the region, shaping the modern identity of communities like Falls City.
