Cattle drives were a major economic activity in the 19th and early 20th century American West, particularly between 1850s and 1910s. In this period, 27 million cattle were driven from Texas to railheads in Kansas, for shipment to stockyards in Louisiana and points east. The long distances covered, the need for periodic rests by riders and animals, and the establishment of railheads led to the development of "cow towns" across the frontier.
Due to the extensive treatment of cattle drives in fiction and film, the horse has become the worldwide iconic image of the American West, where cattle drives still occur.

Movement of cattle
Cattle drives represented a compromise between the desire to get cattle to market as quickly as possible and the need to maintain the animals at a marketable weight. While cattle could be driven as far as in a single day, they would lose so much weight that they would be hard to sell when they reached the end of the trail. Usually they were taken shorter distances each day, allowed periods to rest and graze both at midday and at night. On average, a herd could maintain a healthy weight moving about per day. Such a pace meant that it would take as long as two months to travel from a home ranch to a railhead. The Chisholm Trail, or example, was long.

On average, a single herd of cattle on a long drive (for example, Texas to Kansas railheads) numbered about 3,000 head. To herd the cattle, a crew of at least 10 cowboys was needed, with three horses per cowboy. Cowboys worked in shifts to watch the cattle 24 hours a day, herding them in the proper direction in the daytime and watching them at night to prevent stampedes and deter theft. The crew also included a cook, who drove a chuck wagon, usually pulled by oxen, and a horse wrangler to take charge of the remuda (spare horses). The wrangler on a cattle drive was often a very young cowboy or one of lower social status, but the cook was a particularly well-respected member of the crew, as not only was he in charge of the food, he also was in charge of medical supplies and had a working knowledge of practical medicine.

Origins
Long-distance cattle driving was traditional in Mexico, California, and Texas, and horse herds were sometimes similarly driven. The Spaniards had established the ranching industry in the New World and had begun driving herds northward from Mexico beginning in the 1540s. Small Spanish settlements in Texas derived much of their revenue from horses and cattle driven into Louisiana, though such trade was usually illegal. Most cattle driving routes in the United States were shorter. For example, early 19th-century Pennsylvania cattle drovers travelled to Philadelphia on the Conestoga Road and Lancaster Pike, which ended near the present site of 30th Street Station. Relatively long-distance herding of hogs was also common. In 1815 Timothy Flint "encountered a drove of more than 1,000 cattle and swine" being driven from the interior of Ohio to Philadelphia.
As early as 1836, ranchers in Texas began to drive cattle along a "Beef Trail" to New Orleans. In the 1840s, cattle drives expanded northward into Missouri. The towns of Sedalia, Baxter Springs, Springfield, and St. Louis became principal markets. The Shawnee Trail, also known as the Texas Road or Texas trail, played a significant role in Texas as early as the 1840s. But by 1853, as 3,000 cattle were trailed through western Missouri, local farmers blocked their passage and forced herds to turn back because the Longhorns carried ticks that carried Texas fever. Texas cattle were immune to this disease; but the ticks that they left behind infected the local cattle. By 1855 farmers in western and central Missouri formed vigilance committees, stopped some of the herds, killed any Texas cattle that entered their counties, and a law, effective in December of that year, was passed, banning diseased cattle from being brought into or through the state. Therefore, drovers took their herds up through the eastern edge of Kansas; but there, too, they met opposition from farmers, who induced their territorial legislature to pass a protective law in 1859.
