Terrestrial locomotion is the method of movement of an organism on land. Organisms employ many different methods of movement for a variety of reasons.

Terrestrial locomotion is of great interest to the study of evolution, which determines that aquatic organisms adapted to terrestrial environments. Animal locomotion on land experiences buoyancy and friction to a lesser extent, and gravity to a greater extent.

Horses can use various gaits (patterns of leg movement) during locomotion across solid ground, either naturally or as a result of specialized training by humans.

Gait is the pattern of movement of the limbs of animals, including humans, during locomotion over a solid substrate. Most animals use a variety of gaits, selecting gait based on speed, terrain, the need to maneuver, and energetic efficiency. Different animal species may use different gaits due to differences in anatomy that prevent use of certain gaits, or simply due to evolved innate preferences as a result of habitat differences. While various gaits are given specific names, the complexity of biological systems and interacting with the environment make these distinctions "fuzzy" at best. Gaits are typically classified according to footfall patterns, but recent studies often prefer definitions based on mechanics. The term typically does not refer to limb-based propulsion through fluid mediums such as water or air, but rather to propulsion across a solid substrate by generating reactive forces against it (which can apply to walking while underwater as well as on land).

Due to the rapidity of animal movement, simple direct observation is rarely sufficient to give any insight into the pattern of limb movement. In spite of early attempts to classify gaits based on footprints or the sound of footfalls, it was not until Eadweard Muybridge and Étienne-Jules Marey began taking rapid series of photographs that proper scientific examination of gaits could begin.

Hunting of the American bison, also commonly known as the American buffalo, was an activity fundamental to the economy and society of the Plains Indians peoples who inhabited the vast grasslands on the Interior Plains of North America, before the animal's near-extinction in the late 19th century following United States expansion into the West. Bison hunting was an important spiritual practice and source of material for these groups, especially after the European introduction of the horse in the 16th through 19th centuries enabled new hunting techniques. The species' dramatic decline was the result of habitat loss due to the expansion of ranching and farming in western North America, industrial-scale hunting practiced by settler hunters increased Indigenous hunting pressure due to settler demand for bison hides and meat, and cases of a deliberate policy by settler governments to destroy the food source of the Indigenous peoples.

Chronophotography is a photographic technique from the Victorian era which captures a number of phases of movements. The best known chronophotography works were mostly intended for the scientific study of locomotion, to discover practical information for animal handlers and/or as reference material for artists. Although many results were not intended to be exhibited as moving pictures, there is much overlap with the more or less simultaneous quest to register and exhibit photographic motion pictures.

The Horse in Motion is a series of cabinet cards by Eadweard Muybridge, including six cards that each show a series of six to twelve "automatic electro-photographs" depicting successive phases in the movement of a horse, shot in June 1878. An additional card reprinted the single image of the horse "Occident" trotting at high speed, which had already been published in 1877.

The series became the first example of chronophotography, an early method to photographically record the passing of time, mainly used to document the different phases of locomotion for scientific study. It formed a very influential step in the development of motion pictures. One of the cards (often retitled Sallie Gardner at a Gallop) has even been hailed as "the world's first bit of cinema". Muybridge did project moving images from his photographs with his Zoopraxiscope, from 1880 to 1895, but these were painted on discs and his technology was no more advanced than earlier efforts by others (for instance those by Franz von Uchatius in 1853).

Chapman & Hall is an imprint owned by CRC Press, originally founded as a British publishing house in London in the first half of the 19th century by Edward Chapman and William Hall. Chapman & Hall were publishers for Charles Dickens (from 1840 until 1844 and again from 1858 until 1870), Thomas Carlyle, William Thackeray, Elizabeth Barrett Browning, Anthony Trollope, Eadweard Muybridge and Evelyn Waugh, and his brother Alec Waugh.

The Modoc War, or the Modoc Campaign (also known as the Lava Beds War), was an armed conflict between the Native American Modoc people and the United States Army in northeastern California and southeastern Oregon from 1872 to 1873. Eadweard Muybridge photographed the early part of the US Army's campaign.

Kintpuash, also known as Captain Jack, led 52 warriors in a band of more than 150 Modoc people who left the Klamath Reservation. Occupying defensive positions throughout the lava beds south of Tule Lake (in present-day Lava Beds National Monument), those few warriors resisted for months the more numerous United States Army forces sent against them, which were reinforced with artillery. In April 1873 at a peace commission meeting, Captain Jack and others killed General Edward Canby and Rev. Eleazer Thomas, and wounded two others, mistakenly believing this would encourage the Americans to leave. The Modoc fled back to the lava beds. After U.S. forces were reinforced, some Modoc warriors surrendered and Captain Jack and the last of his band were captured. Jack and five warriors were tried for the murders of the two peace commissioners. Jack and three warriors were executed and two others sentenced to life in prison.
