The County Is Named for a Man Who Didn't Brand His Cattle
The Texas legislature created Maverick County in 1856. It was carved out of Kinney County. The county was named for Samuel A. Maverick, a San Antonio landowner and politician. He was known for not branding his cattle.
That habit gave English a new word. Today 'maverick' means an independent person who does not follow the crowd.
The county was not officially organized until September 4, 1871. Eagle Pass became the county seat. The county covers 1,287 square miles of the Rio Grande plain. The land ranges from flat to gently rolling. Common plants include mesquite, live oak, and prickly pear cactus.
