What caused the cattle drives?

Cattle drives were primarily caused by the demand for beef in the eastern United States following the Civil War, as cities grew and populations increased. The availability of vast open ranges in the West allowed ranchers to raise large herds of cattle, which needed to be transported to railheads for shipment to markets. Additionally, the expansion of the railroads made it feasible to move cattle over long distances, further fueling the cattle drive phenomenon. Economic opportunities for cowboys and ranchers also played a significant role in the rise of these drives during the late 19th century.
