At the start of the 20th century, the United States Department of Agriculture began to establish breeding farms for research, to preserve American horse breeds, and to develop horses for military and agricultural purposes. However, after the end of World War I, the increased use of mechanized transportation resulted in a decline in the horse populations, with a 1926 report noting horse prices were the lowest they had been in 60 years. Horse numbers rebounded in the 1960s, as horses came to be used for recreational purposes.

With the invention of the automobile, the tractor and other internal combustion vehicles, the need for driving horses diminished, beginning with the end of World War I and to an even greater degree after World War II. However, interest in driving competition for horses continued, with the title: Horses in the United States text: the most horses in the world, with the U.S. having the second-highest number. There were an estimated of 20 million horses in March 1915 in the United States. A USDA census in 1959 showed the horse population had dropped to 4.5 million. Numbers began to rebound somewhat, and by 1968 there were about 7 million horses, mostly used for riding. In 2005, there were about 9 million horses. There are about 82,000 feral horses in the western United States under the supervision of the Bureau of Land Management.

Despite the financial and marketing upheavals during the 1970s and 1980s, the decades led to technological innovations and/or widespread use of such improvements as disc brakes, fuel injection, electronic engine control units, and electronic ignition. Front-wheel drive became the standard drive system by the late 1980s. By the mid-1980s, oil prices had fallen sharply, helping lead to the revitalization of the American auto industry. Under the leadership of Lee Iacocca, Chrysler Corporation mounted a comeback after its flirtation with bankruptcy in 1979.

Later, some horses became strayed, lost or stolen, and proliferated into large herds of feral horses that became known as mustangs. Modern domesticated horses that retain Colonial Spanish type include the Spanish Mustang, Choctaw horse, Florida Cracker horse, and the Marsh Tacky. European settlers brought a variety of horses to the Americas. The first imports were smaller animals suited to the size restrictions imposed by ships. Starting in the mid-19th century, larger draft horses began to
