How did the Texas Longhorn breed get to Texas?

Texas Longhorns, but only as a breed name, originated in Texas, they were named as such in the mid 1800's. The cattle from this breed have ancestry from the Spanish long-horned cattle that came with Christopher Columbus when he and many others landed in what was termed the "New World." These cattle, upon becoming feral from escaping from the Spanish settlements, adapted to the land in and around what is now known as Texas (as well as Arizona, New Mexico, California and other Southwestern states) and became very abundant in their populations, until men from back East rounded them up and herded them north to be turned into beef.

Other American breeds stemmed from these Spanish cattle, including Corriente and Florida Cracker/Pineywoods.
