Where did the culture of cattle rancher and cowboy originate ?

The culture of cattle rancher and cowboy originated in the American Southwest, particularly in Texas, during the 19th century. The first cowboys were Mexican vaqueros, or horsemen, who had been working with cattle since the 16th century. They taught American settlers the skills needed to care for and drive cattle. The American cowboy culture developed from the combination of these Mexican traditions and the American settlers' own innovations.
