Texas random facts
Webb County, located in southern Texas along the Mexico border, has a rich and vibrant history dating back thousands of years. The region was originally inhabited by various Indigenous groups, including the Coahuiltecan and Cabeza de Vaca tribes. In 1705, the Spanish government established what is now known as the city of Laredo, making it one of the oldest European settlements in present-day Texas.

During the 19th century, Webb County played a crucial role in the struggle for Mexican independence and the subsequent development of the Texas Republic. In 1836, during the Texas Revolution, Mexican troops led by General José de Urrea were defeated by the Texian forces at the Battle of San Patricio, which took place near present-day San Patricio, a community within Webb County.

Following the Texas Revolution, Laredo became an important trading center, connecting the United States and Mexico. The city's location along the Rio Grande made it a key point for trade and transportation, leading to its rapid growth. In 1848, the Treaty of Guadalupe Hidalgo ended the Mexican-American War, and Laredo became part of the United States.

The late 19th and early 20th centuries brought significant changes to Webb County. The arrival of the railroad in the 1880s further stimulated economic growth, as it provided an efficient means of importing goods and exporting local agricultural products. This led to the expansion of ranching and agriculture industries in the region. Additionally, the discovery of oil and gas reserves in the early 20th century brought further prosperity and development to the county.

Today, Webb County continues to thrive as a bustling border city and a hub of trade between the United States and Mexico. With a rich cultural heritage and a vibrant economy, the county serves as an important intersection of history, commerce, and diversity in Texas.
