Rise of the cowboy

As English-speaking traders and settlers expanded westward, English and Spanish traditions, language and culture merged to some degree. Before the Mexican-American War in 1848, New England merchants who traveled by ship to California encountered both hacendados and vaqueros, trading manufactured goods for the hides and tallow produced from vast cattle ranches. 

American traders along what later became known as the Santa Fe Trail had similar contacts with vaquero life. Starting with these early encounters, the lifestyle and language of the vaquero began a transformation which merged with English cultural traditions and produced what became known in American culture as the "cowboy".

The arrival of English-speaking settlers in Texas began in 1821, while California did not see a large influx of settlers from the United States until after the Mexican-American War. However, in slightly different ways, both areas contributed to the evolution of the iconic American cowboy. Particularly with the arrival of railroads, and an increased demand for beef in the wake of the American Civil War, older traditions combined with the need to drive cattle from the ranches where they were raised to the nearest railheads, often hundreds of miles away.

By the 1880s, the expansion of the cattle industry resulted in a need for additional open range. Thus many ranchers expanded into the northwest, where there were still large tracts of unsettled grassland. Texas cattle were herded north, into the Rocky Mountain west and the Dakotas.

The cowboy adapted much of his gear to the colder conditions, and westward movement of the industry also led to intermingling of regional traditions from California to Texas, often with the cowboy taking the most useful elements of each.
